About the Model *00 Drumtraks and this Manual
In the tradition of SCFs fully-programmable performance synthesizers, the Model 400
Drumtraks simplifies the creation of highly complex and convincing rhythmic
arrangements. The design strikes a remarkable balance between ease of use and depth
of functions. In addition to enabling its thirteen digitally-stored percussion sounds to
be recorded, overdubbed and edited with perfect timing, this flexible, multi-track
rhythm sequencer easily programs the variations which keep things rhythmically
interesting: individual instrument volume and tuning, "swing" balance, accents, and
tempo changes. Yet the Drumtraks price is a fraction of the price of the equivalent
real instruments and multi-track recorder.
Each instrument is playable with its own key: Bass, Snare, Rim, Tom 1, Tom 2, Crash
Cymbal, Ride Cymbal, Closed Hi-Hat, Open Hi-Hat, Claps, Tambourine, Cowbell,
Cabasa. The instruments have already been professionally-recorded for studio-quality
sound and a character that records well on tape.
As a digital recording instrument, the Drumtraks can do things which are impossible
with tape. Multi-tracking, mixing, editing, copying, and erasing can be done without
re-recording, splicing, or accumulating noise and distortion through the processes of
"mix-down" and "bouncing" parts between tape tracks. The Drumtraks contains a
programmable mixer with a monophonic output (which can drive stereo headphones).
For control by external mixers or processors, six audio channels (plus the metronome)
are available at the back panel through standard 1/4-inch phone jacks (see Section 9).
The Drumtracks has two primary modes: pattern and song. Basically, songs are made
by chaining patterns together. The memory capacity of 3289 notes can be allocated to
up to 99 different patterns, any of which can be up to 100 measures long in any time
signature. Tempo range is 40 - 250 beats-per-minute. Each overdub of a pattern can be
recorded with a different instrument volume or tuning, in real time (exactly as
played), or auto-corrected to one of eight levels of resolution. Any part of an
instrumental track can be
(appended).
erased.
Patterns
can
be
copied
and
added
together
Up to 99 songs can be defined, which can consist of up to 100 steps. Steps specify how
the song is built by selecting patterns and inserting volume or tempo changes. Songs,
too, can be edited, copied and appended.
The Drumtraks memory is retained even when power is off thanks to a backup battery
with a ten-year life. For permanent storage and reprogramming, the built-in interface
can be used to store the contents of memory on a common cassette.
All functional information is displayed on four eight-segment LEDs. For performance,
two jacks for optional footswitches allow "hands-free" starting and stopping of songs,
pattern or song selection, and pattern repetition.
There are two built-in interface systems. For older sequencers or rhythm units and
sync-to-tape there is a selectable 24, 48 or 96 pulse-per-quarter note clock input, and
a 24- or 48-pulse clock output. For operation with computer-controlled sequencers, the
new MIDI interface is also included. This enables the Drumtraks to synchronize to
SCI?s new Model 610 Six-Trak multi-timbral synthesizer /sequencer, or any other MIDIequipped instrument. (For example, the Drumtraks can be played with full velocity
control from the keyboard of the Prophet-T8.)
CM400A
11/83
The Drumtraks has several levels of operation, allowing you both to learn how to use it
immediately and to later explore its many options. For example, to start recording
your own two-measure patterns, you simply select a pattern number, select record
mode, then press RUN. An internal metronome provides the basic beat. As the pattern
repeats itself (or, "loops") you can overdub any of the percussion instruments.
After becoming familiar with basic operation, you can change the number of measures
in the pattern, the time signature (to any value), accents, error correct and swing
parameters.
This manual begins with basic setup (Section 1), followed by the simplest operation,
pattern playback (Section 2). After showing how to play patterns, the manual covers
how to record and edit your own patterns (Sections 3 and 4). You can then build
(Section 5) and play (Section 6) songs using pre-programmed or custom patterns. Then
try some of the more advanced song functions (Section 7).
To keep instructions as stream-lined as possible, most explanatory material has been
organized under Details (Section 1*). Refer also to the enclosed card which contains
brief instructions and descriptions of all controls and indicators.

The Drumtraks can store 99 songs, numbered 00-98. (Song 99 is always blank, for use
as a "stop" function.) Basically, songs are chains of pattern selections. Each song can
contain 100 steps. Steps are directions which tell the song to switch patterns, volumes,
or tempo. This section covers simple pattern chaining. Other song functions are
covered in Section 7.

Volume range for each instrument is limited to the values 0 through 15. In other words
you canft add two 10-level volume changes to get a volume change of 20.
Volume changes are always effective. That is, if the song ends with an overall
decrease in volume, each loop will get quieter. Conversely, each loop will get louder
(to the maximum value of 15 for each instrument) if it has an overall increase. To
defeat this feature, add a compensating volume change (in the opposite direction) at
the end of the song.

TEMPO CHANGE steps are in the form, e.g., "up 9" or "down 12," meaning
accelerating nine or decelerating twelve tempo values, respectively. For example if
the song is at 105 bpm and is increased by nine tempo steps, the new tempo will be 125
bpm. Likewise, the step, down twelve, would change from 105 to 86 bpm. If the initial
song tempo were changed to 94, the same tempo change steps would produce tempos
of 109 and 78, respectively.

9 USING CHANNEL OUTPUTS
If you have become familiar with the PER INSTRUMENT VOLUME control, you are
aware that the Drumtraks has its own level-mixing facilities. But the internal mixer
does not have pan facilities. In normal use all six audio channels plus the metronome
are summed into a monophonic signal at the AUDIO OUT jack.
For maximum flexibility the output of each audio channel and the metronome are
available through separate back-panel jacks. This allows you to create the desired
stereo image with an external mixer. The mixer output can be used live or to drive a
pair of tape tracks.
The channel outputs are still controlled by the PER INSTRUMENT VOLUME knob. For
maximum signal-to-noise ratio, instrument volumes should be as high as possible. If
using an external mixer you may want to set or program all instrument volumes to
maximum level. The external mixer will also be handy to induce non-programmed
increases and decreases in volume. Equalization can be used to slightly or radically
alter the instrument tone. If available, effects devices such as chorus or delay can be
inserted into any Drumtraks channel or applied to the mixer outputs. For example, the
normal brief decay of most of the instruments can be synthetically lengthened with a
regenerative delay line. Delay lines can also be used for synchro-sonic effects, in
which precisely-timed echoes are rhythmically intermingled with the original material.
While recording, the metronome appears through AUDIO OUT, but not at the
METRONOME OUT jack. During playback, the metronome does not appear through
AUDIO OUT but does appear at METRONOME OUT. As the metronome is dc-coupled,
lt may actually be heard as a "double-click," which should not be used for a click
track. (For an ac-coupled clock signal, see paragraph 10-2.) When multi-tracking, the
metronome beat may be redundant or unnecessary when percussion is present (on other
tracks), but may be extremely useful when the percussion is highly syncopated, is less
dense, or is "sitting out" for a few measures.
The metronome signal is a very wide pulse that can be used to clock triggered
sequencers (such as SCPs Pro-One, or the Prophet-600 Arpeggiator—which can be
advanced through its footswitch jack). Since the metronome appears on the beat note
of the time signature, in 4/4 the sequencer or arpeggiator could play quarter notesBut finer resolution can be obtained by adjusting the time signature and tempo. For
example, to get an eighth-note clock you could use a time signature of 8/8 (or, for
even higher resolution, 16/16 or 32/32.)

While MIDI is preferred for syncing instruments, MIDI cannot interface to many earlier

Program Dump
A Drumtraks program is the set of all pattern and song data. There is an operation
which is used to transfer programs between Drumtraks units.
To load a pattern from the master to the slave, on the slave:
Hold ENTER, press 3.
This causes the slave to send a program dump request to the master. The master will
respond by sending the entire contents of its memory to the slave (erasing the slave's
former program).
11-* Use with Sequencer
The Drumtraks can be connected to the Model 610 Six-Trak, so multi-timbre sequences
record, overdub, and playback with the Drumtraks in synchronization.
The SCI Model 64 contains one set of MIDI connectors for use with a MIDI synthesizer.
Rather than with MIDI, the Drumtraks interfaces to the Model 64 by way of the 24- or
48-PPQN clock interface. Since the Drumtraks contains its own extensive memory and
editing facilities, the MIDI sequencer is not needed.
However, super-sequencers will inevitably appear that will link all MIDI instruments
into one programmable system. In addition to the MIDI functions discussed above, the
following applies to operation in future MIDI syterns:
Mode
When power is switched on, the Drumtraks is set to Omni On mode. In this mode, it
will ignore any channel designations, playing all received key events in the range of
keyboard numbers to which it is sensitive (see Figure 11-2 for key numbers).
If the master sequencer sends an Omni Mode Off command to the Drumtraks, the
Drumtraks will then listen for key events only on the MIDI channel to which it is set.
Channel
When it leaves the factory, the Drumtraks basic channel is set to Channel 15.
To display the channel number:
Hold both ENTER and 0.
To change the channel number:
While holding ENTER and 0, select channel (1-16) with INC/DEC.
If the channel number is changed it will remain changed even if power is switched off.
MIDI Clock
When a slave Drumtraks receives a start command over MIDI, it automatically
switches itself to receives MIDI clocks. This switching can also be done manually:
Hold both TEMPO switches.
Press ENTER.
Press DEC three times, to move the decimal point all the way Left.
To switch back to internal clock mode, press ENTER again. (The decimal point
will go off.)

14 DETAILS
Accent In conjunction with an instrument key, the ACCENT switch is of course used to
emphasize a part. While emphasis can also be programmed using PER INSTRUMENT
VOLUME, this uses much more memory than does the ACCENT switch.
Append To create a new pattern by adding one pattern to the end of another.
Copy To record an existing pattern or song under a second number.
Pattern copying can be a very handy tool. For example, you can have a set of basic
patterns which can be copied to form the basis of more varied overdubs. As opposed to
making a song of twelve identical patterns, you can easily generate twelve variations
of one basic pattern.
CLK IN/OUT A pre-MIDI interface system for sequencers and rhythm units. The
Drumtraks has a switchable 24, 48, or 96 pulse per-quarter-note (PPQN) input and a 24
or 48 PPQN output (see paragraph 10-1). Other units may (or may not) operate from 16
to 96 clocks per quarter note.
CLOCK OUT is used to interface with the Model 64 Sequencer, as shown in Figure
10-2.
Erase tostrument A feature which can be used to delete all or part of an instrument
from a pattern (regardless of tuning). To erase selectively, hit the instrument key on
(or just slightly before) the undesired note. To completely erase an instrument, hold its
key throughout the pattern loop.
In RECORD MODE, this feature can be used to "thin out" a pattern which is being
recorded (on tape). (If tape recording from AUDIO OUT with the Drumtraks in
RECORD MODE, you would probably turn METRONOME VOLUME all the way down.)
Error Correct This feature allows you to create perfectly-timed patterns. Error
correct ranges from 1/2 to 1/96, in ten values: 1/2, 1/4, 1/6 (quarter triplet), 1/8, 1/12
(eighth triplet), 1/16, 1/24 (sixteenth triplet), 1/32, 1/48, 1/96.
For example, error correct is set by default to 1/16. This means that as you record or
overdub parts, the Drumtraks will only allow notes to fall exactly on sixteenth-note
beats.
With a value of 1/2, all "real-time" parts would be corrected to one of two places in
the (4/4) measure. At the other extreme, a value of 1/96 would provide 96 recording
points in the measure, which is virtually the same as "real-time." INC raises value,
DEC lowers it.
While editing or overdubbing it is often useful to adjust the error-correct value to the
way the instrument is used. For example, usually one overdubs percussion parts from

Step An instruction which builds a song. A song can have up to 100 steps.
Swing Swing is a playback function only. However, the swing value is recorded with the
pattern so that each time the pattern is selected, it will always play with the
previously-selected swing value.
On playback of patterns with a beat value of a quarter note (3/4, 4/4, 5/4, etc.), by
varying the swing value you can change the syncopation of the eighth notes.
represents a change in emphasis off of the precise eighth-note beat.
Swing
The Drumtraks swing value is set by default to 50%, This means that the two eighth
notes which make a quarter note have equal time. In other words they play exactly as
written. Swing can be adjusted to 54, 58, 62, 66, or 70%. By changing the swing value,
for example, to 66%, the first eighth note would be lengthened from 1/2 to 2/3 of a
quarter note and the second would be shortened from 1/2 to 1/3 of the same duration.
In a song, selecting patterns with different swing values helps break up the monotony
of perfect rhythm. (In this way it is the opposite of Error Correct.) Note that in a
song, to change the swing of a pattern, you would actually first copy the pattern,
change the swing of the copy, then in the song, select the original pattern then the
copy.
Tempo Number of beats-per-minute (bpm). The Drumtraks ranges 40-250, with the
values shown in the chart on page 7-9.
The maximum value for a single tempo change step is plus or minus 15. Therefore for
tempo changes greater than this, simply put two or more successive tempo change
steps into the song.
Although usually irrelevant to most drum machine work, it is sometimes handy to have
at hand the classical names for tempo ranges:

The 400 always powers-up with Omni Mode On: the Basic Channel is set to 15 (N =
1110) at the factory.
The channel can be changed from the front panel by:
1. Hold both ENTER and 0. This will display the current channel number.
2. Select n$w channel number, if desired, using INC/DEC (1 through 16).
The channel is ignored with Omni Mode On and checked with Omni Mode Off. The
Mode Change commands must be sent to the correct channel in either mode.
The channel number is non-volatile, that is, if the channel number is changed it will
remain changed even if power is switched off.
