Uberheim 08-8 Owner's Manual Introduction
l INTRODUCTION
CONGRATULATIONS! ! !
And welcome to the 0B-8. You have Just purchased a state-of-the-art
electronic music device. The 08-8 is easy to use, yet contains many
features that allow for Very precise sound synthesis.
A refinement and evolution of Oberheim's 0B-X and 08-Xa, the OB-8
contains more features and better performance, with fewer parts, which means
more reliability,
The most important functions on the 0B-8 are available simply by
pressing the desired button Or turning the proper knob; yet there are many -
other less used functions that can be accessed indirectly, allowing control
Over many functions without the need for more knobs and buttons.
The 08-8 interfaces with the Oberheim DSX Digital Polyphonic Sequencer,
which adds greatly to the 0B-8's capability by recording and playing notes
as well as patch changes.
As with any piece of equipment, the more that you know about it, the
better you will be able to use it. So read this instruction manual
often, to familiarize yourself with the capability of this instrument.
And experiment! You won't discover all of the 0B-8's capability unless
you do.
Good luck!
Page 1
Uberheim 08-8 Owner's Manual Setting Up
2, SETTING UP
1) First, make sure the 115/230 Voltage switch on the rear panel is
set for the local AC power;
2) Apply power and plug into your sound system;
4) Select a programmed sound by pressing a GROUP (A thru D, or any
combination) and a PROGRAM (1 thru 8);
5) Set the MASTER VOLUME control to an appropriate level.
6) Play!
2.1. Master Volume
You can adjust the output volume of the OB-8 with the MASTER
VOLUME control in the upper left hand corner. This control
simultaneously controls both the stereo outputs and the mono
output.
2.2. Master Tune
The MASTER TUNE control allows the instrument to be fine-tuned to
other instruments. When this control is within the "dead-zone"
near the top center, the instrument is tuned to standard A-440
pitch.
2.3. Auto Tunin
The AUTO button activates the Autotune program. This program
tunes the initial frequency and volts/octave (tracking) of the
oscillators one at a time, and the PROGRAM lights will flash one
after the other, to indicate which voice is currently being tuned.
u 3) Press "AUTO" to tune all of the oscillators;
| While the Autotune program is running, the outputs and all
controls are disabled. The Autotune program also calibrates the
— pitch bend lever for zero bend and the vibrato lever for zero
vibrato. It is important that the levers be left alone during
Autotune, so that the Autotune program can set the zero points
accurately.
If a particular voice cannot be tuned by the Auto-tune program,
the PROGRAM light representing that voice will flash for two
seconds, and the computer will automatically disable the out-of-
tune voice.
2.4. Pan Pots
— The 08-8 comes from the factory with Voices 1-4 panned all the way
to the left and Voices 5-8 panned all the way to the right. Each
of the voices can be panned anywhere in the stereo outputs by
setting the pan pots located on the right side of the unit.

SETTE QQ
Fig. 3-1: Programmer Controls
There are two types of programs stored in the 0OB-8's memory:
PATCH PROGRAMS that store sounds.
SPLIT/DOUBLE PROGRAMS that store combinations of Patch
Programs.
The 08-8 comes from the factory pre-programmed with 104 Patch
Programs, 12 Split Programs, and 12 Double Programs. These
include a great variety of sounds which will quickly acquaint you
with the capabilities of your instrument. The 0B-8 Programmed
Patches book details these factory programs
5.1. Recalling Patch Programs
The Patch Programs on the 08-8 are divided into 15 GROUPS of 8
PROGRAMS each. The 15 GROUPS are selected by pressing the four
GROUP buttons ("A", "B", "C", 4 npn) individually OR in any
combination ("AB", "AC", "ВС", "ABC", "ABCD", etc.). The PROGRAM
within the selected GROUP is then selected by pressing one of the
eight PROGRAM buttons.
3.2. Modifying Patch Programs
Any sound recalled by the programmer can be modified (edited) by
changing the controls on the front panel.
The controls add to, or subtract from, the settings stored in the
computer program. For example, the release time of the LOUDNESS
ENVELOPE can be made longer than programmed simply by turning up
the RELEASE control on the LOUDNESS ENVELOPE. This feature allows
quick yet smooth modifications of existing programs. If it is
desired to further increase or decrease a control setting, and the
control is already at its maximum or minimum position, simply
rotate the control all the way in the opposite direction and then
make your desired setting.
Modifying the program does not change the program stored in the
0B-8's memory, and the original, unmodified sound program can be
recalled by pressing the appropriate PROGRAM button again.
For more information, see the sections titled "SOUND PROGRAMMING
CONTROLS" and "PAGE 2 CONTROLS",
Page 3
Oberheim 0B-8 Owner's Manual Using The Programmer
5.3. Creating New Sounds | |
The 08-8 can be used to create completely new sounds, rather than
alter existing sounds as described above, by using the MANUAL
MODE. ‚In MANUAL, the sound of the instrument will reflect the
actual physical settings of the controls.
NOTE: The MANUAL MODE cannot be used while in SPLIT or DOUBLE
modes, and the 2ND PAGE of controls have no effect (except for
VOICE ENABLES -- see "PAGE 2")
3.4, Writing Programs |
New, modified, or even existing programs can be written into the
0B-8's memory. This is done with the following procedure:
1) Press and hold WRITE until the WRITE light comes on;
2) Select a GROUP (A thru D, or any combination)
3) Select a PROGRAM (1 thru 8).
The write operation actually occurs when the PROGRAM switch is
pressed, with the WRITE light on.
NOTE: Before any programs can be written, the MEMORY PROTECT
SWITCH on the rear panel must be OFF.
5.5. Moving Programs
It is possible to move a program from one program memory location
to another. To do this, simply select the program you wish to
move, and then write into the desired new program location, as
described above.

5.2. Modulation
MODULATION This lever controls the amount of modulation from the LFO to
LEVER the assigned Oscillators. Pulling this control towards the
front of the unit will add modulation. If the DEPTH control
is on, this lever will add more modulation to the amount set
by the DEPTH control.
Reversing It is possible to reverse the direction of the modulation
The Lever lever. To do so, hold down the LOWER and OSC 2 ONLY buttons
above and below the pitch bend lever while you turn the power
on. To return the pitch bend to normal operation, repeat the
procedure. When it leaves the factory the 08-8 is set for
the regular direction (the right one!).
RATE This controls the rate of the LFO. The rate can be adjusted
from about .06 Hz to 50 Hz.
Waveform The various waveforms of the LFO are shown in the following
Selection table: | |
DESIRED RATE KNOB WHILE BEND LEVER
WAVEF ORM SHOULD BE: IS:
TRIANGLE Pushed Down Straight
SQUARE Pulled Up Straight
UP SAWTOOTH Pulled Up UP (towards the front of

DOWN SAWTOOTH Pulled Up DOWN (towards the rear of
the unit)
NOISE Pushed Down UP (towards the front of
the unit)
SAMPLE /HOLD Pushed Down DOWN (towards the rear of
the unit)
Table 5-1: Performance LFO Modulation Waveforms
DEPTH This control allows you to control the depth of the LFO
without using the MODULATION LEVER. Turning the knob |
determines the modulation depth, and pulling up on the knob
puts this control into effect.
The amount of depth set by this control is added to the depth
controlled by the MODULATION LEVER or the external MODULATION
PEDAL.

Pitch Bend
This lever is used to bend the pitches of notes being played.
Pulling it towards the front of the unit causes the pitch to
go up, and pushing it towards the rear causes the pltch to go
down. Its range is determined by the AMOUNT switch.
It is possible to reverse the direction of the pitch bend
lever. To do so, hold down the UPPER and AMOUNT buttons
above and below the pitch bend lever while you turn the power
on. To return the pitch bend to normal operation, repeat the
procedure. When it leaves the factory the 0B-8 is set for
the regular direction (the right one!).
This switch determines the range of the PITCH BEND LEVER.
When this switch is off, the PITCH BEND LEVER has a range of
Up or down one whole step (e.g. "C" could move up to a "D" or
down to a "Bb").
When the AMOUNT switch is on, the PITCH BEND LEVER can be
programmed to bend an amount between a quarter-tone and an
octave up or down. To program the amount of pitch bend,
press and hold the AMOUNT button, and while holding it, press
any key in the lowest octave of the keyboard. The interval
between the lowest C and the key pressed becomes the maximum
range of the bend lever. For example, holding the AMOUNT
button and pressing the lowest Eb on the keyboard (Eb0) will
program a maximum bend range of a minor third up or down.
The amount of pitch bend with the AMOUNT light on will remain
at this same programmed value until changed, even if the
power is turned off.
When this switch is on, the PITCH BEND lever bends only
Oscillator 2 of each voice. When this switch is off, the
BEND LEVER bends both Oscillators.
Bending anly Oscillator 2 has an interesting, timbral effect
on programs in which Oscillator 2 is in SYNC.
These buttons are used to assign all of the functions of the
MODULATION and PITCH BEND controls, to either half of the
keyboard when in the SPLIT or DOUBLE mode. The LOWER and
UPPER switches have separate functions for the ARPEGGIATOR,
so that the arpeggiator and modulation can be assigned to
Upper or Lower independently.
The LOWER and UPPER switches will both come on when not in
the SPLIT or DOUBLE modes, and will revert to their previous
settings upon re-entering Split or Double.
The Pitch Bend lever will also bend the filter cutoff
frequency if KBD TRACK (in the filter section) is turned on.

This button turns the arpeggiator on and off. The ARPEGGIATE
button operates while either arpegglator or modulation is
displayed (whether the MODE switch is on or off).
When this button is on, notes played on the keyboard will
arpeggiate.
When this button is on, held notes or a held chord will
arpeggiate. The operations for holding and transposing an

5.4.1. Transposing The Arpeggiator
The 00-68's arpeggiator can transpose arpeggiating notes by up
to five programmable intervals. The six buttons at the front
of the MODULATION PANEL become the six transpose buttons
(five plus no transposition) only while the MODE button is
pressed. Thus, the Modulation Panel actually contains three
pages of controls: Modulation (MODE button off), Arpgeggiator
(MODE button on) and Arpeggiator Transpositions (MODE button
held down).

This button is used to produce a sustained note or chord.
To use, press the HOLD button and simultaneously play one or
more notes, and then release the HOLD button. The note or
notes played will now be sustained indefinitely. You can
play notes one at a time or all at once, while holding down
the HOLD button. To cancel the hold function, press HOLD a
second time, but be sure not to hold down any keys.
The HOLD button and the HOLD FOOTSWITCH operate the same and
can be used interchangeably.
HOLD may be used in Split and Double to sustain different
sounds at once, and with the Arpeggiator to arpeggiate a
sequence of notes without having to hold them down. (see
"ARPEGGIATOR")

CHORD The HOLD and CHORD buttons can be used together to play
Chord Hold chords with one key. First, select the desired notes by
using the HOLD function as described above. Then, press the
CHORD switch. The held chord will cease sounding. By
playing low C (CO) on the keyboard, the held chord will be
reproduced as previously played. Playing notes above CO will
transpose the chord up by a corresponding interval. If the G
above lowest C (GO) is played, the chord will sound
transposed up a Fifth; if the C two octaves above the lowest
C (C2) is played, the chord will sound transposed up by two
octaves. The actual note being played will not sound.
Transpose The transposing effect can be limited to a part of the
Limit keyboard. Press the CHORD button, and while holding it press
Chord Latch
a key on the keyboard. This key becomes the Transpose Limit.
A held chord will not be transposed above this key. Above
the Transpose Limit, the remaining voices will play normally.
The Transpose Limit remains stored in memory until changed.
NOTE: The Transpose Limit can only be changed while a chord is
being held.
The chord will always be transposed by the lowest note on the
keyboard below the Transpose Limit, even in split. However,
individual notes can be played above the note transposing the
chord as well as above the Transpose Limit. To exit the
CHORD mode, simply press the HOLD switch.
A held chord can be latched so it will remain gated on.
Press and hold the CHORD button, and then press the HOLD
button (be sure to release the HOLD button before releasing
the CHORD button). A held chord will now stay on (be latched
on). Te turn off the chord latch, repeat the above
procedure.
The arpeggiator will continually cycle through a latched
chord, and will not restart when the transposition is
changed.
The chord latch is off when the 08-8 is first turned on.

2.6. Foot Switches
The Foot Switch inputs are designed for use with the Model S-0BX Foot
Switch. The S-0BX contains a momentary, normally open switch.
SUSTAIN Pressing the Sustain Switch Causes the RELEASE on all
Envelope Generators to be set to the amount programmed in
each Patch (on PAGE 2). The PEDAL SUSTAIN time has the same
range as the front panel RELEASE TIME of the envelope
generators. In SPLIT or DOUBLE, the two patches will each
die out according to their own programmed PEDAL SUSTAIN time.

5.7. Foot Pedals
The Pedal inputs are designed for use with the Model P-0BX Foot Pedal.
They are also designed to respond to Control Voltages, from the DSX
Sequencer or other sources.
VOLUME The Volume Pedal varies the volume of the 08-8 from zero to
the MASTER VOLUME setting on the front panel.
The VOLUME jack also can be used as a Control Voltage output
that will vary depending upon the setting of the MASTER
VOLUME control on the front panel.
VIBRATO The Vibrato Pedal functions like the Vibrato Lever on the
MODULATION PANEL. It allows the user to add vibrato from the
LFO in the MODULATION PANEL to whatever oscillators are
assigned to it.
FILTER This pedal controls the FILTER FREQUENCY of all voices. The
range of the pedal is from a slightly lower frequency than
when the pedal is not connected, to a significantly higher
frequency.

6. SOUND PROGRAMMING CONTROLS
The controls described on the next few pages are used control the sound
of the 08-8. It is the settings of these controls that is actually stored
in the 0B-8's program memory.
Any sound recalled by the programmer can be modified (edited) by
changing these Sound Programming Controls. The controls add to, or subtract
from, the settings stored in the computer program. For example, the release
time of the LOUDNESS ENVELOPE can be made longer than programmed simply by
turning up the RELEASE control on the LOUDNESS ENVELOPE. This feature
allows quick yet smooth modifications of existing programs.
When selecting a program, the front panel settings do not affect the
sound of the instrument. For instance, if a sound had originally been
programmed with a FILTER FREQUENCY setting at 12 o'clock, but later the
program is recalled with the FILTER FREQUENCY control set at 9 o'clock, the
program sound will be the same as if the FILTER FREQUENCY control was set at
12 o'clock. If it is desired to further increase or decrease a control
setting, and the control is already at its maximum or minimum position,
simply rotate the control all the way in the opposite direction and then
make your desired setting.

6.2. Filter
The Voltage Controlled Low Pass Filter (VCF) are used to control the
brightness of the sound, filtering out the higher frequencies (the "buzz")
in a very controllable manner. The Filter is arguably the most important
component in a synthesizer, because it is the primary control of the timbre,
or tone color of the sound. Because of this, the filter on each voice of
the 08-8 can be set to two modes: 2-Pole and a 4-Pole. In the 08-8, the
Filter Section also selects the sound sources (Oscillators and Noise) that
are used in the patch.

Fig. 6-3: Filter Controls
FREQUENCY This control sets the initial cut-off frequency of the
Filter.
RESONANCE This control determines the amount of resonance ("Q" or
"emphasis") of the Filter. The RESONANCE emphasizes the cut-
off frequency of the Filter. As the RESONANCE is increased,
the overall volume of the sound will increase in the 2-POLE
mode and decrease in the 4-POLE mode.
MODULATION This control determines the amount of Filter Envelope which
modulates the Filter. Modulation of the Filter by the
Envelope is a critical element in the synthesis of brass
sounds as well as creating percussion in organ sounds, to
name just a few uses. The MODULATION control also determines
how much Filter Envelope will modulate 05С 2 when the F-ENV
switch is on. The LFO can also modulate the Filter. See
"MODULATION SECTION"
0SC 1 When this switch is on, Oscillator 1 is routed into the
ON Filter. |
OSC 2 When either of these switches are on, Oscillator 2 is routed
HALF/FULL into the Filter. The FULL switch selects the full output of
the oscillator and the HALF switch selects a signal level
approximately 5 db below full output.
NOISE When this switch is on the Noise Generator is routed into the
ON Filter.
Раде 25
Oberheim 0B-8 Owner's Manual Sound Programming Controls
4-POLE Turning this switch on selects the 4-POLE filter mode. when
this switch is off the 2-POLE filter mode is selected. The
effect of this switch is to change the sharpness of the
filtering effect. The 4-POLE mode has a 24db/octave slope
(sharper), which results in a more full sound. The 2-POLE
mode has a 12db/octave slope (more gradual), which results in
a brighter sound.
KBD This switch adds the control voltage from the keyboard to
TRACK control the Filter Frequency. When on, the Filter in each
voice will track the keyboard, and "open up" as higher notes
are played. The TRANSPOSE and MASTER TUNE controls will also
control the Filter when TRACK is switched on.
When KBD TRACK is on, the pitch bend lever also controls the
Filter Frequency. In SPLIT or DOUBLE the filter will only
track the bend lever if it is assigned to it with the UPPER
and LOWER buttons in the bend box.
6.3. Envelopes
The Envelope Generators control the timing of the sound. It is the
Envelopes that make a long sound long, and a short sound short. For
example, the difference between a cresting ocean wave, and an explosion.
There are two envelopes on each voice of the 08-8; one that controls the
Filter (VCF) for timbral control, and one that controls the Amplifier (VCA)
for volume control.

counter-clockwise. |
The Decay section of the envelope comes into operation as

This control sets the level the Filter Envelope goes to
following its initial decay, as set by the DECAY control.
The Envelope will stay at the Sustain Level as long as the
key on the keyboard is held down.
Unce the key is released, the Envelope moves to the Release
section, and completes its cycle. The RELEASE control sets
the time the Filter takes to go from the Sustain level, to
the off level. If the SUSTAIN control is set to minimum, the
Release section will have no effect on the sound if the key
is pressed and held down. If the key is pressed and
immediately let go (in less time than the combined Attack and
Decay time), then the Release Section will still have an
effect.
The Release of Envelope can be cut short by pressing the
WRITE button.
When the F-ENV switch is on, the Filter Envelope modulates
USC 2 as well as the FILTER. The pitch of OSC 2 will
directly correspond to the shape of this Envelope. The ATTACK
determines how fast OSC 2's pitch will rise, the DECAY
determines how fast OSC 2 will decrease in pitch to the level
set by the SUSTAIN control, and. the RELEASE determines how
fast OSC 2 will decrease in pitch after a note has been
released. The MODULATION control in the Filter Section will
control the range of the effect of the Filter Envelope an
both the Filter as well as Oscillator 2.

This control determines the rate of portamento or "glide" of
each voice as that voice's pitch is changed. Note that the
portamento of the 08-8 is polyphonic, so each voice will
glide from note to note independently of all other notes.
Portamento also functions in UNISON mode. There are several
Portamento Modes. For more information, see "PORTAMENTO
MODES".
When switched on, causes all voices to be sounded by one key
depression. In UNISON, the 08-8 keyboard operates with low
note rule, which means that the lowest note played on the
keyboard will always have priority. When in SPLIT, the
UNISON mode is independent for the two halves of the
keyboard, so if the upper half is in UNISON, then only the
lowest note of the upper half of the keyboard will affect it.
This control allows Oscillator 2 to be tuned either flat or
sharp relative to Oscillator 1. Turning the control to the
left makes Oscillator 2 go flat and to the right makes it go
sharp. The LED above the OSC 2 DETUNE control turns on when
the Oscillator 2 is detuned from Oscillator 1.

you were to listen to an LFO directly, you would not hear anything; however
by controlling the frequency or pulse width of an oscillator or filter, the
effect of an LFO becomes apparent.
The 08-8 contains three LFOs: two are controlled from the Modulation

TRIG POINT
Any of the waveforms of the front panel LFU can be selected
as the Triggered LFO Waveform by selecting KBD TRIG as the
waveform on page 1 and then selecting the desired waveform on
page 2. For example, if KBD TRIG is selected on page 1 and
UP SAWTOOTH is selected on page 2, the result will be an UP
SAWTOOTH that is reset every time a new key is pressed.

7.3. LFO Envelopes
Besides the FILTER ENVELOPE and VOLUME ENVELOPE, there are two simple
envelope generators for the LFO, one for DEPTH 1 (OSC 1 FRQ, OSC 2 FRQ, and
FILTER FRQ) and another for DEPTH 2 (OSC 1 PW, OSC 2 PW, and VOL MOD). The
[ЕО envelope generators enable changes in modulation depth as a note plays,
just as the FILTER ENVELOPE and VOLUME ENVELOPE enable changes in the filter
and volume levels as note plays.

These controls set the time delay of the LFO's enveloape
generators. The delay ranges from a minimum of zero to a
max imum of 3.5 seconds. The delay is reset each time a new
note is played. MOD 1 affects OSC 1 FRQ, OSC 2 FRQ, and
FILTER FRQ, and MOD 2 affects OSC 1 PW, OSC 2 PW, and VOL
MOD.
These controls set the attack time of the LFO's envelope
generators. The attack time ranges from a minimum of zero to
a maximum of 3.5 seconds. The attack time is reset each time
a new note is played. MOD 1 affects OSC 1 FRQ, OSC 2 FRQ,
and FILTER FRQ, and MOD 2 affects OSC 1 PW, OSC 2 PW, and VOL
MOD.

These switches invert the LFO envelope generators. INVERT 1
affects OSC 1 FRQ, OSC 2 FRQ, and FILTER FRQ, and INVERT 2
affects OSC 1 PW, OSC 2 PW, and VOL MOD.
With INVERT off, the LFO will start each note at zero
modulation and increase to the depth set by the appropriate
DEPTH control in the time set by the DELAY and ATTACK
controls.
With INVERT on, the LFO will start each note at the
modulation depth set by the DEPTH control and decrease to
zero modulation in the time set by the DELAY and ATTACK
controls.
This adds 1/4 of the keyboard to the rate of the LFO. The
LFO speed will double every four octaves on the keyboard
(e.g.-CO to C4).
This switch acts something like the F-ENV switch on page |.
Pressing this switch enables the LFO 2 envelope to control
the rate of the LFO. The LFO 2 DEPTH controls the amount of
modulation. DELAY 2, ATTACK 2, and INVERT 2 will all affect
the rate of the LFO when this switch is on.

When the MATCH switch is on, all voices will portamento at
“exactly the same rate. When the MATCH switch is off, the
voices will portamento at slightly different rates.
This switch quantizes the sliding portamento into semitone
steps.
THIS MODE CAN BE TURNED ON ONLY WHILE IN UNISON MODE. when
legato portamento is on, notes will slide only when played
legato, e.g. without releasing the key while going from one
note to another. When notes are played detached, no
portamento will occur. This feature enables portamento to be
used expressively while soloing. Legato Portamento can be
used in conjunction with any of the other portamento modes,
but only in unison. Turning off UNISON will automatically
turn this mode off.
This switch makes the glide time between notes independent of
the interval between the notes, e.g. it will take the same
time to glide from CO to C£0 as it would from CO to C6. The
range of the glide time is smaller than with the regular
portamento mode. Note that BEND PORTAMENTO and EQUAL TIME
PORTAMENTO cannot be on at the same time.
This mode is essentially identical to the equal time
portamento but the "shape" of the glide is exponential
instead of linear. This means that the pitch will glide
slower and slower as it gets closer to the destination note.
This kind of portamento was used on the Oberheim Modular 2,4
& 8 voice synthesizers. Note that EXPONENTIAL PORTAMENTO
cannot be on at the same time as either EQUAL TIME or BEND
PORTAMENTO.

the gliss is controlled by the PORTAMENTO control on either
page.
Press and hold the PORTAMENTO BEND control, and play a note
on the keyboard. The C two octaves from the bottom of the
keyboard (C2) equals zero bend, and each key away from C2 (up
or down) equals a quarter-tone, e.g. pressing D3 will set
notes to gliss from a perfect fifth above.
Held Chords being transposed will not portamento if the
PORTAMENTO BEND is on. Notes being Arpeggiated operate in
the opposite manner: they will portamento only if the
PORTAMENTO BEND is on. So, when using portamento with Held
Chords that are being transposed and Arpeggiated, you have a
choice: With the PORTAMENTO BEND on, each arpeggiated note
will portamento; with the PORTAMENTO BEND off, only the chord

Oberheim 08-8 Owner's Manual Cassette Interface
8, CASSETTE INTERFACE
The 08-8 is equipped with a Cassette Interface which enables programs
contained in the program memory to be stored externally on an audio
cassette. All that 1s required to use the Cassette Interface feature is an
audio cassette recorder with reasonable frequency response and a pair of
mini-plug to mini-plug audio connecting cables.
NOTE: The cassette player must have an earphone or ext. speaker output
(a LINE OUT will not work).
NOTE: The 08-8 Cassette Interface is not compatible with other Oberheim
synthesizers.
8.1. Tape Recorder Hookup
Connect the Earphone or Speaker output of your cassette recorder
(a Line output will not work) to the jack labeled "TO OUTPUT" on
the rear of the 0B-8. Connect the "TO LINE INPUT" jack on the
rear panel of the 08-8 to the Line or Aux input of your cassette
recorder. If the recorder does not have one, connect the "TO MIC
INPUT" jack on the rear panel to the Mic input of your cassette
recorder.
NOTE: To reduce hum, the "TO LINE INPUT" and "TO MIC INPUT" jacks have
no ground connection. For this reason, it is necessary to connect
both the Input and the Output cables when recording data onto the
cassette recorder.
8.2. Cassette Interface Controls
CASSETTE This switch on the rear panel enables the cassette interface.
ENABLE When the Cassette Interface is enabled, the CASSETTE LIGHT on
the front panel lights up and all normal functions on the
instrument are disabled.
RECORD RECORD shares a switch with the WRITE button. Pressing
RECORD allows you to record your programs onto tape.
PLAY PLAY shares a switch with the UPPER button. Pressing PLAY
allows you to play your programs from the tape into the 08-8.
CHECK CHECK shares a switch with the MANUAL button. Pressing CHECK
allows you to check your program recordings without writing
them into the OB-8.
HOLD This button cancels any Cassette operation at any time.

8.3. Recording Programs Onto Tape
1) Enable the Cassette Interface with the switch on the rear
| panel.
2) Press the RECORD switch on the tape recorder. You should now
hear a steady tone through the main outputs of the 08-8. The
MASTER VOLUME control will adjust the volume of the tone
heard in the 0B-8's outputs, but will not affect the level of
the Cassette Interface Output.
3) Press the RECORD switch on the 0B-8. ‘After the RECORD switch
is pressed, ten seconds of the steady "leader" tone will be
sent out followed by sixteen seconds of the actual memory
information. During these twenty-six seconds, the light on
the RECORD switch will be on. The GROUP lights (A, B, C, D)
come on in sequential order ("А", "В", "АВ", "С", "AC", etc.)
Indicating that information transfer is taking place.
The RECORD function can be cancelled by pressing the HOLD button.
| 8.4. Playing Programs From Tape Into The OB-8
1) enable the Cassette Interface with the switch on the rear
| panel.
2) Press PLAY on the tape recorder. You will be able to monitor
| the tape through the main outputs of the 08-8. The MASTER
VOLUME will control the volume for monitoring the tape.
on the 08-8. At least three seconds of the "leader" tone
must come between pressing PLAY and the rough sound of the
memory information. The light on the PLAY switch will be lit
| from the time the switch is pressed until the first of the
memory information is recognized. At that point, the GROUP
lights (A, B, C, D) come on in sequential order ("A", "В"
"АВ", "С", "AC", "ABC", etc.) indicating which group is being
transferred. The Splits and Doubles are transferred last.
3) As soon as the "leader" tone is heard, press the PLAY switch
If the MEMORY PROTECT switch on the Rear Panel of the 0B-8 is
set to PROTECT, the PLAY light will not operate.
4) If an error is detected, the PLAY light will flash.
The PLAY function can be cancelled by pressing the HOLD button.
NOTE: If a cassette of patches from an 08-8 with A7 or previous
software is loaded into an 08-8 with A8 software, it is possible
that some of the new features of the A8 software (portamento
and LFO invert functions) will be turned on in some of the
programs. To eliminate them, simply edit them out of each patch
and re-write it into memory. For more information, see the
SOFTWARE REVISIONS section of this manual.

Possible Causes of Tape Transfer Errors
A)
B)
C)
D)
There is a dropout on the tape.
The playback volume is too high or too low. Some trial and
error may be required. Generally the best level is as high
as possible before distorion occurs (approximately 3/4 of the
way up). If the playback volume is too low, the 0B-8 will
not acknowledge the data at all.
The tone control may be set improperly. It is important that
the tone control(s) be set so that neither the high nor the
low frequencies are attenuated.
The Batteries in the cassette machine are too weak.
The Cassette Interface is designed to work with portable cassette
recorders having an "Earphone", "Speaker", or "Monitor" output.
The Interface is not designed to work with tape recorders having
only a line output. Our experience is that monophonic recorders
work more reliably that stereo units. One cassette recorder that
we have found to work well with the cassette interface on all of
Oberheim's products is the Superscope C-200LP. |

Software Revisions / Calibrations
Since its release in January 1983, the software in the 08-8 has been
upgraded through several software revisions. These revisions have
added new features and improved performance to existing features.
All 0B-8s can be updated with new software by any authorized Oberheim
The latest computer software (as of August 1983) is labeled A8. For a
quick check to see which software is in your 0B-8, enter PAGE 2 by
pressing the CHORD/PAGE 2 button twice, and hold it down on the second
push. While holding, press the SYNC button. While holding both of
these buttons down, the software version will be displayed in the
Programmer Section. If you currently have version A8 software, the
NOTE: If a cassette of patches from an 0B-8 with previous software is

service Center.
10.1. Displaying The Software Revision
GROUP A and the PROGRAM 8 lights will light up.
ll. SOFTWARE CALIBRATIONS
The 0B-8 has a number of calibrations that are stored in its computer
memory. Most of these are envelope time calibrations that are set at
the factory so that the envelope generators in the OB-8 will be matched
from voice to voice and between the upper and lower voices. These
calibrations are unique to each 08-8 and are stored on tape
automatically each time you save your programs. This feature is on all
UB-8s having software version A6 or above. Under normal operation of
the 0B-8, these calibrations should never be altered, but the following
provisions for setting them can be very useful if the unusual situation
arises in which the 0B-8 is not functioning properly.

Tape Storage of Calibrations
The calibrations of your particular 0B-8 stored in computer memory are
recorded on tape automatically each time you save your programs. If
for some reason your 0B-8 gets out of calibration (due to memory drop),
the calibrations on tape can be loaded back into the 08-8 in much the
Same manner as patch programs are loaded into the OB-8 from tape:
1) Enable the Cassette Interface with the switch on the rear
panel.
2) Press PLAY on the tape recorder. You will be able to monitor
the tape through the main outputs of the 08-8. The MASTER
VOLUME will control the volume for monitoring the tape.
3) Hold down all six buttons in the FILTER section (OSC 1 ON,
USC 2 HALF, OSC 2 FULL, NOISE, 4 POLE, and TRACK).
4) As soon as the "leader" tone is heard, press the PLAY switch
on the 08-8, At least three seconds of the "leader" tone
must come between pressing PLAY and the rough sound of the
memory information. The light on the PLAY switch will be 11+
from the time the switch is pressed until the first of the
memory information is recognized. At that point, the GROUP
lights (A, B, C, D) come on in sequential order.
If the MEMORY PROTECT switch on the Rear Panel of the 08-8 is
set to PROTECT, the PLAY light will not operate.
4) If an error is detected, the PLAY light will flash.
The PLAY function can be cancelled by pressing the HOLD button.
The calibrations should only be loaded in if the OB-8 has lost its
programs, or the envelope generators do not seem to be operating
properly. It is important that these calibrations are loaded in only
from a tape made from the same 0B-8, otherwise the wrong calibrations
will be loaded in.
Checking a data tape will also check the calibrations on that tape (See
CASSETTE INTERFACE).

Master Reset
If for some reason (memory drop, for example), the OB-8 seems to be
functioning improperly (i.e. four voices out of tune with the other
four, envelope generators are unmatched, transpose won't work), it is
possible to reset the computer inside the 08-8.
To reset the 08-8's computer, press all 8 PROGRAM buttons and the SPLIT
button at the same time (use your elbow), WHILE MEMORY PROTECT IS OFF.
The reason this a difficult procedure is so that it cannot be done
accidentally, since all the envelope calibrations will be reset to
Zero.
When this reset is done, the envelopes should be matched closely enough
for normal operation, but to match them more accurately, the
calibrations must be loaded in from tape.
NOTE: These functions have been provided as a last resort when there
seems to be no other way to correct a problem of envelope matching or
transpositions not functioning. Since the consequences of these
operations are not user repairable, contact your authorized service
center or Oberheim Customer Service to determine whether or not these
actions should be taken to solve a particular problem.
Reset of All Performance Controls
If this same reset procedure is done with ONLY WITH MEMORY PROTECT ON,
all of the 08-8 functions EXCEPT the envelape calibrations will be
reset. This can be useful when it is desired to reset the arpeggiator
transpositions, bend amount, bend direction, split transpositions, etc.
without affecting any of the calibrations.

NEW PAGE 2 FEATURES
The latest version of the Oberheim 08-8 has eight exciting
new features not listed in the current Owner's Manual. All
of these features are retrofitable to any previously
manufactured 0B-8 at your local Oberheim Service Center.
The new computer software is labeled AB. For a quick check
to see which software is in your 0B-8, enter PAGE 2 by
pressing the CHORD/PAGE 2 button twice, and hold it down on
the second push. While holding, press the SYNC button.
While holding both of these buttons down, the software
version will be displayed in the Programmer Section. If you
currently have version A8 software, the GROUP A and the
PROGRAM 8 lights will light up.
NOTE: If a cassette of patches from an 08-8 with old
software is loaded into an 08-8 with A8 software, it is
possible that some of the new features will be turned on in
some of the programs. To eliminate them, simply edit them
out of each patch and re-write it into memory.
The software version A8 contains the following new features:
1)-- LEGATO PORTAMENTO
2)-- EQUAL TIME LINEAR PORTAMENTO
3)-- EXPONENTIAL PORTAMENTO
4)-- INVERT LFO FREQUENCY MODULATION ON VCO 1
5)-- INVERT LFO PULSE WIDTH MODULATION ON VCO 1
6)-- VEF TRACKING OF THE BEND LEVER
7)-- REVERSABLE BEND LEVER
8)-- REVERSABLE MODULATION LEVER
1) LEGATO PORTAMENTO
This mode is turned on from PAGE 2 with the OSC 1 FULL switch
and is stored in the patch. THIS MODE CAN BE TURNED ON ONLY
WHILE IN UNISON MODE. Turning off UNISON will automatically
turn this mode off. When legato portamento is on, the
portamento (any kind) will be active only when the keyboard
is played legato, e.g. without releasing the key while going
from one note to another.
2) EQUAL TIME LINEAR PORTAMENTO
This mode is turned on from PAGE 2 with the OSC 2 HALF switch
and is stored in the patch. BEND PORTAMENTO (the UNISON
button on PAGE 2) AND EQUAL TIME PORTAMENTO CANNOT BE ON AT
THE SAME TIME. When this mode is active, the glide time
between any note is independant of the interval between the
notes, e.g. it will take the same time to glide from CO to Cl
as it would from CO to C6. The glide time is controlled by
the portamento rate knob. The range of the glide time is
smaller than with the regular portamento mode.
3) EXPONENTIAL PORTAMENTO
This mode is turned on from PAGE 2 with the OSC 2 FULL switch
and is stored in the patch. BEND PORTAMENTO AND EXPONENTIAL
PORTAMENTO CANNOT BE ON AT THE SAME TIME. EQUAL TIME LINEAR
PORTAMENTO AND EXPONENTIAL PORTAMENTO CANNOT BE ON AT THE
SAME TIME. This mode is essentially identical to the equal
time portamento but the "shape" of the glide is exponential
instead of linear. This means that the pitch will glide
slower and slower as it gets closer to the destination note.
This kind of portamento was used on the Oberheim Modular 2,4
& 8 voice synthesizers.
4) INVERT LFO FREQUENCY MODULATION ON VCO 1
This mode is turned on from PAGE 2 with the SYNC switch and
is stored in the patch. With this mode on, the LFO
modulation of VCO l's frequency is out of phase by 180 .
degrees (phase opposition) with respect to the LFO frequency
modulation on VCO 2 and the VCF.
5) INVERT LFO PULSE WIDTH MODULATION ON VCO 1
This mode is turned on from PAGE 2 with the F-ENV switch and
is stored in the patch. With this mode on, the LFO
modulation of VCO 1's pulse width is out of phase by 180
‘degrees (phase opposition) with respect to the LFO pulse
width modulation on VCO 2 and the VOLUME MOD.
6) VCF TRACKED BY THE PITCH BEND LEVER
When VCF TRACK is on, the pitch bend lever controls the VCF
frequency. In SPLIT or DOUBLE the VCF will only track the
bend lever if it is assigned to it with the UPPER and LOWER
buttons in the bend box.
7) REVERSABLE PITCH BEND LEVER
It is now possible to reverse the direction of the pitch bend
lever. To do so, hold down the UPPER and AMOUNT buttons
above and below the pitch bend lever while you turn the power
on. To return the pitch bend to normal operation, repeat the
procedure. This setting is not stored with the patch but
will remain in its current mode even when the power is turned
off. When it leaves the factory the 0B-8 is set for the
regular direction (the right one!).
8) REEVERSABLE MODULATION LEVER
5
Same as for the pitch lever but you must use LOWER and OSC 2
ONLY (above and below the modulation lever) while you turn on
the power.
As with any piece of equipment, the more you know about it,
the better you will be able to use it. So experiment! You
won't discover all of the capabilities of your new PACE 2
controllers unless you do.

There are also a few features of the 08-8 that have existed
in earlier software versions, but have not been explained in
the owner's manual. The following features are on all 0B-8s
having software version A6 or above. Under normal operation
of the 0B-8, these features would never be used, but they can
be very useful if the unusual situation arises in which the
08-8 is not functioning properly.
1) TAPE STORAGE OF CALIBRATIONS
The 08-8 has a number of calibrations that are stored in its
computer memory. Most of these are envelope time
calibrations that are set at the factory so that the envelope
generators in the 0B-8 will be matched from voice to voice
and between the upper and lower voices. These calibrations
are unique to each 08-8 and are stored on tape automatically
each time you save your programs. If for some reason your
0B-8 gets out of calibration (due to memory drop), the
calibrations on tape can be loaded back into the 08-8 by
holding down all six buttons in the FILTER section (OSC 1 ON,
OSC 2 HALF, OSC 2 FULL, NOISE, 4 POLE, and TRACK), then
pressing PLAY and then playing in the tape (MEMORY PROTECT
must be off in order to play in a cassette). The
calibrations should only be loaded in if the 08-8 has lost
its programs, or the envelope generators do not seem to be
operating properly. It is important that these calibrations
are loaded in only from a tape made from the same UB-6,
otherwise the wrong calibrations will be loaded in.
2) MASTER RESET
If for some reason (memory drop, for example), the 08-8 seems
to be functioning improperly (i.e. four voices out of tune
with the other four, envelope generators are unmatched,
transpose won't work), it is possible to reset the computer
inside the 08-8 by pressing all 8 PROGRAM buttons and the
SPLIT button at the same time (use your elbow), WHILE MEMORY
PROTECT IS OFF. The reason we made this a difficult
procedure is so that it cannot be done accidentally, since
all the envelope calibrations will be reset to zero. To then
reload the envelope calibrations, follow the procedure listed
above. When this reset is done, the envelopes should be
matched closely enough for normal operation, but to match
them more accurately, the calibrations must be loaded in from
tape. If the reset 1s done with memory protect on, all of
the 08-8 functions EXCEPT the envelope calibrations will be
reset. This can be useful when it is desired to reset the
arpeggiator transpositions, bend amount, bend direction,
split transpositions, etc. without affecting any of the
calibrations.
NOTE: These functions have been provided as a last resort
when there seems to be no other way to correct a problem of
envelope matching or transpositions not functioning. Since
the consequences of these operations are not user
repairable, contact your authorized service center or
Oberheim Customer Service to determine whether or not these
actions should be taken to solve a particular problem.

MIDI
USING THE 08-8 MIDI INTERFACE
MIDI is an acronym for Musical Instrument Digital Interface. It
is a serial computer interface which enables synthesizers and
computers to communicate. MIDI was designed to be a universal
computer interface through which synthesizers and computers could
communicate regardless of manufacturer. Any synthesizer or
computer having a MIDI interface will connect to an 08-8.
MIDI CONNECTORS
MIDI CONNECTORS are located on the rear panel of the 08-8 or, on
the left end bell of an 0B-8 with a MID! retrofit. The MIDI IN
connector receives MIDI information. The MIDI OUT connector
transmits MIDI information from the synthesizer. Keyboard
information, patch changes, and bend lever/modulation lever
changes generated on an 08-89 will be sent to the MIDI OUT
connector. The MIDI THRU connector is used to pass MIDI
information which wes generated by another synthesizer/ computer.
Information played on an 08-8 is not available at it's own MIDI
THRU connector.
BASIC CONNECTION
The simplest application is to connect 2 08-8's together. The
Master 08-68 will be referred to as Synthesizer A and will, for the
following demcnstrations, be the controller. The second 03-8 will
be referred to as Synthesizer B or the Slave, end will He
controlled by the Master 0B-8. We will use this configuration to
explain MIDI operation and associated controls.
NOTE: WHEN CONNECTING COMPUTER BASED PRODUCTS TOGETHER, MAKE SURE
POWER IS OFF ON BOTH UNITS.
Using .a cable with 5 pin mele DIN connectors on each eng, cunneci
MIDI QUT on the master 08-8 to MIDI IN on the Slave 08-8. Turn
power on and press auto tune. Notes played on the Master 08-6
will also be played by the Slave OB-8.

MIDI SWITCHES AND FUNCTIONS
All MIDI SWITCHES are located in the PAGE 2 feature of the 08-8.
Enter PAGE 2 by rapidly pressing the PAGE 2 switch twice. The Led
for the PAGE 2 switch will light signifying that you are in PAGE

PROGRAM ENABLE / DISABLE — SWITCH "A" (Page 2)
This switch enables and disables two patch related functions: patch
select, and patch data transfer. When the 08-8 is powered up these
functions are disabled.
SELECTING PATCHES — In PAGE 2 on both 08-8's, press the A switch.
The A Led will light, indicating the ability to transmit/receive
program information. Selecting a patch program in PAGE 1 on the
Master OB-8 will select the same patch program on the Slave 08-8.
(EXCLUDING SPLITS 4 DOUBLES).
PATCH TRANSMIT -- "WRITE/RESET" SWITCH (Page 2)
The program enable switch also allows you to transfer patches
from the Master 08-8 to the Slave 0B-8. (NOTE: Memory ‘Protect
must be off on the Slave 08-8.) In PAGE 1 on the Master 08-8,
select patch D-1. Now, enter Page 2 and press the WRITE button on
the Master 08-8. After a short delay, the WRITE Led will light,
indicating that the program Patch D-1 has been transferred from
the memory of the Master 0B-8 to memory location D-1 in the Slave
08-8. To play this patch on the Slave 08-8, you must return to
PAGE 1 and re-select Patch D-1, or select a different patch on the
Master 0B-8 then select D-1. Now both 08-8's will play Patch D-1.
PITCH BEND AND MODULATION LEVER ENABLE / DISABLE -- "B" SWITCH (Page 2)
When the 08-8 is powered on, the pitch bend and modulation levers
are not sent or received over MIDI (disabled). They must be enabled
on both units each time power is turned on.
In PAGE 2 on both CB-B's, press the B switch. The B Led will
light, indicating the ability to transmit and receive pitch
bend/modulation information. When the Slave 0B-8 receives pitch
bend/modulation information, it uses that information based on the
settings on it's own Performance/Modulation Panel. In other
words, if the slave machine is set to bend a semi-tone, it will
bend at that interval regardless of the bend setting of the master
machine. |

08-8 MIDI Interface Page 3
ON / OFF — "C" SWITCH (Page 2)
The power up or default condition is OMNI MODE on, C Led lit.
When OMNI MODE is on, the 08-8 receives on ALL MIDI channels and
transmits all data on Basic Channel N only.
When OMNI MODE is off, the 0B-8 receives on MIDI Basic Channel N
only. When OMNI MODE is off in the transmitting 08-8, it will
transmit on two MIDI channels. Notes above the split-point are sent
on Basic Channel N. Notes below split-point are sent on the Basic
Channel plus one. Example: When power is turned on the Basic
Channel is always channel 1. After OMNI MODE is turned OFF, the
upper half of keyboard is sent on channel 1, and the lower is sent
on channel 2. If the Basic Channel is changed to channel 5, the
upper will be channel 5 and the lower will be channel 6.

NOTE :
The power up or default MIDI Basic Channel is channel 1. To change
the Basic Channel, PRESS & HOLD the D switch. The D Led the 1 led
will light, indicating that the Basic Channel is channel !. If you
select 5, the 5 led will light, indicating that the Basic Channel is
now channel 5.
Do not attempt to change MIDI channels while notes are playing.
This may cause a note to get "stuck" ON. IF this happens, try the
DSX RE-ENABLE / TURN OFF MIDI NOTES switch (see next section) or
switch in & out of cassette mode or power OFF/ON to reset.
DSX RE-ENABLE / TURN OFF MIDI NOTES -- "TRACK" SWITCH (Page 2)
NOTE:
The hardware design of the 0B-8 does not allow MIDI IN and the DSX
COMPUTER INTERFACE to be used at the same time without possible
MIDI errors. The 0B-8 receives information from the DSX sequencer
thru the 40 pin connector on the rear panel of the 08-8. anv time
MIDI IN information is detected by the 08-8, the DSX interface is
DISABLED and the DSX RE-ENABLE Led will light. While the DSX RE-
ENABLE Led is on, the DSX cannot play the 05-8. Pressing the OSX
RE-ENABLE switch causes the Led to go out and re~enables the
parallel interface.
The Yamaha synthesizers have a MIDI option called "active sense".
They are ALWAYS transmitting MIDI data even if no notes are being
played. Connecting a DX-7 to MIDI IN on an JB-8 will not allow
you to use the DSX. The 0B-8 will continually detect MIDI
information and will keep the parallel interface disabled.

Using the 08-8 MIDI Interface Page 5
USING MIDI WITH THE DSX
The sequencing power of the DSX can be used with ANY synthesizer
having a MIDI interface. With a DSX sequencer playing the Master
08-8, any synthesizer connected to the MIDI OUT connector of the
Master 0B-8 will DOUBLE the notes played by the 08-8. — Also, you
can use the 08-8 to merely pass the DSX information to the MIDI
OUT connector causing any synthesizer with MIDI IN to be
controlled by the DSX.

The 08-8 defaults to OMNI ON upon power up. If the 08-8 is a receiver,
it will receive on all channels. If the 0B8-B is the transmitter, it will
transmit on one channel. (selectable)
The 0B-8 may also be operated in OMNI OFF mode. If the D8-8 is e
receiver, it will now receive ONLY on the selected Basic Channel. If the 08-
8 is used as transmitter, it will now transmit the upper half of the
keyboard on the Basic Channel, and the lower half will be transmitted on the
Basic Channel + l. Pitch bend, progam select, etc. will be transmitted on
both channels. The Channel Split Point is the same as the regular Split
Point. (default is middle С.) THIS MODE IS INDEPENDENT OF SPLIT MODE.
The 08-8 is always in POLY MODE.

08-8 Revision BS Software
Operation Guide
8/15/84
* This revision of 08-8 software (version 85) has been made to improve
the dperation of the 0B-8 with the DSX, as well as to add some new MIDI
Features. - For a complete explanation of the 0B-8's existing features,
please refer to the 0B-8 Owner's Manual and the 0B-8 Revision BJ Software
Operation Guide. To verify the software version number of an 08-8, press
the PAGE 2 button twice and hold it down the second time it is pressed (the
PAGE 2 led should now be lit). While holding down the PAGE 2 button, press т
end hold the SYNC button. While holding both switches down, the PROGRAMMER
leds will display the 08-8's software version number. If the B led in the
GROUP section and the 5 led in the PROGRAM section are now lit, the software
version is-B5. This version has all of the features of version B3, as well
as the following NEW FEATURES: |
1. The Sustain footswitch on the 0B~8 has now been added to the MID!
interface. -This means that when two OB-85 are connected together through
MIDI, the Sustain Footswitch on th MASTER OB-8 (the one using MIDI QUT) will
also control the Sustain on the SLAVE 0B-8 (the one using MIDI IN). This
feeture can also be used by other synthesizers that transmit and recieve
Sustain Footswitch information on MIDI.
2. When an 08-8 with MIDI is connected to a DSX Digital Sequencer, the
MIDI output of tre 0B-3 will send out the notes played by the DSX through
the MIDI output. This allows additional synthesizers with MIDI to play the
same thing that the 08-8 is playing from the DSX. Now with version B5 (and
a DSX with version 3.00 or above), it is possible to have the DSX contral
the 08-8 AND a synthesizer connected to the 0B-8's MIDI OUT INDEPENDENTLY.
By assigning the DSX's CV outputs to the 0B-8 MIDI (see "DSX REVISION 3.00
INSTRUCTIONS"), the DSX will ‘send whatever the DSX's CVs are playing to the
0B-8's MIDI OUT without the OB-8 playing it, The notes that the 08-8 are
playing will NOT be sent to the MIDI OUT, so that the two synthesizers can
play completely independently. This also means that when this feature is
used, and the DSX is not playing anything on the CVs, no notes will be sent
to the 08-8's MIDI OUT regardless of what is being played on the 08-3.
3. The overall speed of operation on the Ü3-8 has been increased to
allow the DSX to communicate with the 0B-8 faster, resulting in increased
accuracy of the timing of notes played by the DSA.
4, The range of vibrato lever has been changed for better
competability.

08-8 MIDI Implementation Version B-5 August 15,1984 Page 6
MODES
The NB-8 defaults to OMNI ON upon power up. If the 0B-8 is a receiver,
it will receive on all channels. If the 08-8 is the transmitter, it will
transmit on one channel. (selectable)
The 08-8 may also be operated in OMNI OFF mode. If the 05-8 is a
receiver, it will now receive ONLY on the selected Basic Channel. If the OB-
8 is used as transmitter, it will now transmit the upper half of the
keyboard on the Basic Channel, and the lower half will be transmitted on the
Basic Channel + 1. Pitch bend, progam select, etc. will be transmitted on
both channels. The Channel Split Point is the same as the regular Split
Point. (default is middle C.) THIS MODE IS INDEPENDENT OF SPLIT MODE.
The 08-8 is always in POLY MODE.
FRONT PANEL SELECTABLE FUNCTIONS (ON PAGE TWO OF FRONT PANEL)
NOTE: Functions must be enabled on source AND destination machines to work.
Switch Function
A Enable/Disable program change and program dump.
Power-On default: disablec.
B Enable/Disable Pitch bend and modulation controls.
Default: disabled.
C OMNI ON/OFF. Toggle OMNI status. Power-On default is OMNI ON
(led is lit.) (see MODES)
D Channel display/select. Press and hold down D button to display
or select the Basic Channel.
WRITE Dump current STORED program to MIDI. NOTE: SWITCH "A", "PROGRAM
ENABLE", MUST BE ENABLED FOR A DUMP TO OCCUR.
TRACK Sequencer Re-Enable / Turn off MIDI Notes.
IMPORTANT: The 08-8 cannot RECEIVE MIDI info and be run by the
DSX sequencer simultaneously (due to hardware design.) So, to
prevent MIDI data errors, the sequencer is DISABLED upon
receiving any data from MIDI IN. This condition is displayed by
the TRACK led on page 2. When you no longer wish to use the UB-
8 as a receiver, end you want to use the DSX, disconnect MIDI IN
and press the TRACK button. The led will go out, the sequencer
will work normally, and any notes turned on by MIDI will be
turned off.
Power-On default: TRACK light off, Sequencer Enabled.
