INTRODUCTION
Congratulations on your purchase of a Yamaha OX21 Digital Sequence Recorder! Your QX21 Digital
Sequence Recorder offers high-performance 2-track digital sequencing in any MIDI-based digital music
system. The QX21 is capable of recording anything you play on any Yamaha DX synthesizer or other
MIDI keyboard — complete with touch response and function parameters such as pitch bend, modulation,
etc. The things you record will be true to life. You can also write in notes in the “step” mode, letting
you create pieces that would be impossible to play live. Overdubbing capability is practically unlimited,
and you can control more than one FM tone generator — say a DX11 Digital Programmable Algorithm
Synthesizer and a TX81Z FM Tone Generator — letting you sequence more than one voice at a time.
Furthermore, a range of useful editing and other control functions lets you modify and enhance your
compositions with ease. And there's a cassette interface so you can save all your hard work on a standard
cassette recorder for later use. |
The QX21 Digital Sequence Recorder can give you virtually unlimited capability for creative, digital
music production.
IMPORTANT
This manual is organized in tutorial form. Therefore, in order to fully understand all aspects of operating
the QX21, we urge you to go through the manual and try out each operation as it is described.

PRECAUTIONS
e Avoid placing the X21 in locations exposed to direct sunlight or high temperatures, excessively high or low
humidity, high dust concentrations, or vibration.
e Be sure to connect the QX21 to an AC power supply that meets the power supply specifications listed on the
rear of the unit.
® if there is any danger of lightning occurring nearby, remove the power plug from the wall socket in advance.
® Be sure to make all connections properly, as described in the “CONNECTIONS” section (next page).
® To avoid damaging your speakers and other playback equipment, turn off the power of all related equipment
before making connections.
® Do not use excessive force in handling control switches and knobs.
e To avoid broken cords and short circuits, be sure to unplug all connectors by grasping the respective plugs -
— NOT the cords.
* Remove the power plug from the AC mains socket.if the unit is not to be used for an extended period of time.
® Remove all plugs and connections if the unit is to be transported, to prevent damage to the cords and jacks.
® Do notuse solvents such as benzene or paint thinner to clean the unit. Do not use insecticides or other pressurized
spray products in proximity to the unit. Wipe off the exterior with soft cloth.
STORAGE OF DATA
e This unit is equipped with a back-up function for recorded data. However,
important data should be saved onto cassette tape before starting a new re-
cording.
EFFECTS ON OTHER ELECTRONIC EQUIPMENT
® Since this unit incorporates digital circuitry, simultaneous use of other equip-
ment such as TVs, radios, etc. in close proximity may cause noise and erroneous
operation. If this occurs, separate the affected units sufficiently to eliminate
the problem. If is also a good idea to use separate line filters on each piece —-
of equipment.

BASIC RECORDING & EDITING PROCEDURES
Real time and step recording with the QX21 are remarkably simple procedures. But before you try recording anything,
make sure that the MIDI OUT from your keyboard is connected to the QX21 MIDI IN terminal, and that the MIDI
OUT from the QX21 is connected to the MIDI IN of your keyboard, as shown in the basic connection diagram
given on page 4. Also, note that with the QX21 YOU WILL ALWAYS RECORD ON TRACK 1.
Assuming that you are just starting and that nothing has been recorded in the QX21,
REAL TIME both TRACK LEDs will be out, as will the RECORD and START LEDs, and job
RECORDING A-1 (REALTIME REC) on the job lists will be selected. Set the TEMPO control
(Job A-1) for the desired tempo—indicated by the flashing dot at the lower right-hand corner
of the digital LED display. Press the RECORD button to activate the record standby
mode. The RECORD LED should now be lit, and the TRACK 1 LED should be
flashing. Now press the START button and the QX21 will give you a two-measure
count in: the metronome will beep 8 times (if 4/4 time, the default time signature, Pa
is selected) and the digital LED display will count from —8 to —1. All you have to
do is start playing on the keyboard from the first measure, using the metronome
as a rhythmic guide (note that the metronome beeps at a higher pitch on the first
beat of each measure). When you're finished, press the STOP/CONTINUE button
to exit the record mode. Note that if you press the STOP/CONTINUE button in the
middle of a measure, the record mode will be exited at the end of that measure.
Now, to hear what you have just recorded, simply press the START button. Tempo
can be adjusted during playback by using the TEMPO control. When playback
finishes the playback mode will be exited and the LED display will read in-
dicating the end of the recording.

The ERASE “job” lets you erase all of track 1, or all track 1 data following a specified
measure. To erase what you have just recorded, first call the ERASE job (job B-4)
by pressing the JOB/STEP SIZE B/D selector 4 times if you start with job A-1 active
(LEDs "B” and "4" will be lit}. The LED display will now alternately read and

now use the —1 and +1 buttons to scroll through the recording (one press moves
one measure in the specified direction, while holding one of the buttons down scrolls
continuously in the specified direction) in order to specify the measure from which
you want to begin the erase operation. To erase the entire track, scroll to measure
1. To erase everything from measure 3 onwards, scroll to measure 3. Press the START
button to actually execute the erase operation. To cancel the ERASE job without
executing the ERASE operation, simply press RESET. If you erase the entire track
the TRACK 1 LED will go out, indicting that there is no more data in the track.
Once ERASE has been executed, the QX21 will automatically return to the stop
mode and job A-1 will be selected.

Overdubbing—recording one track over another—on the QX21 is accomplished by
using two jobs: EXCHANGE and TRACK DOWN. Both functions are described
below. EXCHANGE, however, is used for the first overdub only, while TRACK
DOWN is used for all subsequent overdubs.
Although using the EXCHANGE job is the first step in overdubbing over the first
recorded track, it is also useful in several other situations. Basically, all EXCHANGE
does is to interchange the data on tracks 1 and 2: the data from track 1 is moved
to track 2, while the data on track 2 is moved to track 1. For the purpose of ov-
erdubbing, the EXCHANGE job is called (press JOB/STEP SIZE B/D selector once
from job A-1) after recording the first track on TRACK 1. When the EXCHANGE
job is called the LED display will read [£L]. Execute the EXCHANGE job by pressing
the START button. You can cancel the EXCHANGE job prior to executing by pressing
Using the TRACK
Buttons
™ Track Down (Job B-3)
RESET. The material you recorded on TRACK 1 will naw be on TRACK 2 (the TRACK
2 LED will light), and since TRACK 2 was empty, TRACK 1 will now be empty
and its LED will go out. If you now play the recording by pressing the START button,
you will actually be hearing TRACK 2. Now to overdub the second track, simply
follow the normal real time record process: press RECORD and then PLAY. You
will now be able to record the second track—on TRACK 1—while listening to the
first track which is now on Track 2. Press STOP/CONTINUE when you're finished.
To hear both tracks played together, simply press START.
Since some operations can only be carried out on data on TRACK 1, the EXCHANGE
job is also used to swap tracks in order to perform some operation—ERASE, for
example—on the TRACK 2 data. The normal track positions can then be resumed
by executing EXCHANGE again.

When a track contains data, the corresponding TRACK button can be used to turn
that track on or off. This is handy when both tracks contain data, but you want
to listen to only the material recorded on one track. Pressing the TRACK button
alternates between the ON and OFF modes: LED ON = track ON.
This job is only used when both TRACK 1 and 2 contain data, such as prior to
recording a third overdub. The TRACK DOWN job combines (mixes) the data on
TRACK 1 and TRACK 2, and places the result on TRACK 2. TRACK 1 is left empty.
Now, supposing you have recorded your first two tracks and have data on both
TRACK 1 and TRACK 2, call the TRACK DOWN job by pressing the JOB/STEP
SIZE B/D selector three times (LEDs “B” and “3” will be lit). The LED display
will read EER indicating that the TRACK DOWN job is active. Execute the job by
pressing the START button (or cancel by pressing RESET). The TRACK 1 indicator
will go out, and tracks 1 and 2 will now be combined on TRACK 2. Verify this by
playing TRACK 2. The third overdub can now be recorded on TRACK 1 in the normal
way. Subsequent overdubs are all carried out in the same fashion: using REAL
TIME REC and TRACK DOWN.

= In the step recording mode, notes, chords and rests are input one at a time from
S TEP RECORDING the recording keyboard, the note length of each being determined by the STEP
SIZE setting. Since the data is not entered in real time, this mode is ideal for entering
extremely fast or complex lines which would be impossible to play in real time.
The step recording mode is activated by pressing the STEP button. The TRACK 1
indicator will light, the STEP indicator will flash, and the current measure number
(or end mark) will be displayed on the digital LED display. If TRACK 1 contains
no data you will automatically begin recording from the first measure. If, however,
you will begin recording from a specific measure within or at the end of al-
ready -recorded material, use the —1 and +1 buttons at this point to locate the
measure from which you will begin recording.
The actual length of the each note entered is specified using the JOB/STEP SIZE
selectors and the note markings on the job lists. The available note lengths are:
A-1 = Л 1/16 note.
A-2 = A 1/32 note.
A-3 = J 1/64 note.
A-4 = "A 1/32 note triplet.
A-5 = "A 1/16 note triplet.
A-6 = ‘M 1/8 note triplet.
B-1 = J) 1/8 note.
B-2 = , 1/4 note.

B-5 = JM. 1/16 note with 100% gate time.
; B-6 = 1/8 note with 100% gate time.
NOTE:
Normal note gate time is 80%. The 100% gate time notes are used to create
legato phrasings.

To begin actual recording, press the RECORD button—the RECORD indicator will
> light—and then the START button—the START indicator will light. The QX21 is
| now waiting for you to input the first note. To record, first select the desired note
; length—just as you normally select different jobs—using the JOB/STEP SIZE se-
lectors, play the appropriate note or chord on the keyboard, select the next note
length, play the next note or chord on the keyboard......and so on. The measure
count will be updated as you “fill” each measure with notes, chords and rests.
The dots at the bottom of the LED display indicate which beat of the current measure
is being entered.
| 1st beat 2nd beat 3rd beat 4th beat

All the available note lengths can be entered as rests simply by pressing the REST
button instead of playing a note or chord on the keyboard. The +1 button can be
used at any point during a measure to fill the remainder of the measure with rests
and skip to the beginning of the next measure. If the +1 button is pressed at the
beginning of a measure, a full measure rest will be entered. The —1 button can
be used to return to the beginning of the current measure in order to re-enter the
data for that measure. |
Notes or rests can be tied to the following note or rest, of any length, using the
TIE button. Only notes of the same pitch can be tied together. For example, to tie
a 1/16 note to another 1/16 note, enter the first 1/16 note, then press the T1E button.
This effectively creates an 1/8 note (two tied 1/16 notes). A 1/4 note could be
tied to an 1/8 note by first entering the 1/4 note, selecting the 1/8 note length
on the job lists, then pressing the TIE button. This will give you the equivalent of
a dotted 1/4 note. Naturally, notes can be tied across the measure lines. When
you are finished recording press the STOP/CONTINUE button. Press START to
hear what you have recorded.
*When entering single notes in the step write mode, be sure to enter ONE NOTE
AT A TIME! If you play a second note while the previous note is still held, both
notes will be entered as a chord on the same beat.

SEQUENCING MULTIPLE TONE GENERATORS
Connecting Multiple
Tone Generators
With the QX21 it is possible to sequence more than one tone generator at a time—up
to a total of 16—by setting different MIDI recording channel numbers for each “part”
which is to be played by a different voice. Since the data for all voices is output
from the QX21's single MIDI OUT terminal, the tone generators used must be ;
“daisy-chained” together using their MIDI THROUGH terminals. A practical mui-
ti-voice setup using the Yamaha DX11 synthesizer (as recording keyboard and
one tone generator) and one or more Yamaha TX81Z FM TONE GENERATOR units
is shown in the following system diagram.

MIDI Channel
Number
(Job A-6)
This job sets the MIDI channel number for material recorded in either the real time
or step recording modes. The power-on default mode is that the QX21 records
on the same channel as the MIDI transmit channel of the recording keyboard. To
independently sequence different tone generators, however, the respective parts
must be recorded using specific MIDI channel numbers, and the tone generators
set to receive only on the corresponding channels. For example, in a simple system
using a DX11 and one TZ81Z, when the DX11 receives on channel 1, the TX817
should be set to receive on channel 2. First you might record a bass line with the
QX21 RECORDING MIDI CHANNEL set to 1, and then a piano part with the
RECORDING MIDI CHANNEL set to 2. If your DX11 is then set to play a bass
voice and the TX81Z a piano voice, the respective parts will be played by the ap-
propriate voices when the QX21 is started.
To set the 0X21 RECORDING MIDI CHANNEL, first call job A-6 (you should know
how by now). The LED display will alternately read indicating that the MIDI
job is active, and indicating that the default "ALL CHANNELS” parameter is
selected. The —1 and +1 buttons are then used to select the desired MIDI channel
number: ALL > 1 >23... — 16. Press RESET to return to job A-1 once the
desired MIDI channel has been set.
* Remember that the MIDI channel number set for specific part MUST match the
MIDI channel number of the corresponding tone generator.
NOTE:
Muiti-timbral synthesizers and tone generators such as the DX11 and TX81Z
can act as up to eight independent instruments, each being controlled by a
different MIDI channel. This means that you can playback multi-part com-
positions using just one DX11 or TX81Z. See the owner's manual for your
synthesizer or tone generator.

This job makes it possible to set the OX21 to record at different time signatures.
The number of metronome beats per measure are adjusted accordingly. Call the
BEAT/MEAS job, and the LED display will alternately read indicating that the
BEAT/MEAS job is active, and the currently selected BEAT/MEAS value. The default
is 4 (4/4 time). The —1 and +1 buttons are used to select the desired time signature.
The number shown on the LED display indicates the number of beats per bar. A
number alone indicates 1/4 notes, and a number with a dot at its lower right-hand
corner indicates 1/8 notes. The available values are: 1/4 through 16/4, and 1/8
through 16/8. Press RESET to return to job A-1 once the desired value has been
selected.

This job makes it possible to set the QX21 metronome to operate during record
only (the default value), during record and play, at all times (in case you just need
a metronome), or not at all. Call the METRONOME job, and use the —1 and +1
buttons to select the desired mode. The LED display will alternately read in-
dicating that the METRONOME job is active, and the currently selected mode. The
available modes are:
= OFF
= RECORD
= RECORD & PLAY
= ALWAYS
Press RESET to return to the job A-1 once the desired mode has been selected.
Normally, the QX21 is synchronized to its internal clock signal, the speed of which
is controlled using the TEMPO control. In some applications, however, the QX21
can be synchronized to an external MIDI clock signal received at the MIDI IN
terminal. It might, for example, be useful to synchronize QX21 playback to the clock
signal from a MID! rhythm machine such as the Yamaha RX series Digital Rhythm
Programmers. The selection of internal or external clock contro! is made using the
CLOCK job. Call the CLOCK job and the LED display will alternately read
indicating that the CLOCK job is active, and the currently selected mode.
The desired mode is selected using the —1 and +1 buttons. The modes are:
Press RESET to return to job A-1 once the desired mode has been selected.

NOTE:
1. When the INTERNAL clock mode is selected, note resolution is 1/384
measure. When EXTERNAL is selected, note resolution is 1/96 measure.
2. The OX21 record/playback START and STOP functions can be activated
via the QX21's START and STOP buttons, a footswitch connected to the
QX21's rear-panel footswitch jack, or by an external MIDI START/STOP
signal received at the MIDI IN terminal, whether the QX21 is in the IN-
TERNAL or EXTERNAL clock mode.
3. The 0X21 may be made to record under EXTERNAL clock synchronization.
With the EXTERNAL ctock mode selected and the QX21 set to RECORD,
recording will begin immediately when the externai clock START signal
is received.
The QX21 transmits SONG POSITION POINTER data during playback and re-
cording. This data synchronizes the SONG POSITION (current measure) of an
external Yamaha RX21 or RX21L Digital Rhythm Programmer or other MIDI
equipment which is capable of receiving SONG POSITION POINTER data to that
of the QX21.
For example, QX21 play back or recording can be started from any measure, and
the connected Digital Rhythm Programmer will play back from the corresponding
measure,

UTILITY FUNCTIONS
SP í—rL———Ñ o Lo _
All the QX21's utility functions are contained within job lists C and D, which are not listed on the front panel but
are given on the QX21 top panel. These jobs are accessed by using the JOB/STEP SIZE selectors in conjunction
with the RESET button. For example, to call job C-3, hold the RESET button down while pressing the JOB/STEP
SIZE A/C button twice. To call job D-5, hold the RESET button while pressing the JOB/STEP SIZE button 5 times
(the first press switches from the A/C list to the first job of the B/D list).
This job determines whether the QX21 receives and records after touch data (MIDI
After Touch (Job C-1) status codes $An and $Dn). Call job C-1 by holding RESET and pressing the
JOB/STEP SIZE A/C selector 6 times (in order to scroll back to the first job). The
LED display will alternately read indicating that the AFTERTOUCH job is active,
and the currently selected mode. The —1 and +1 buttons are used to turn the function
ON or OFF. The default mode is OFF.

This function should be turned ON when the QX21 is used in a system in which
the recording keyboard has no internal tone generation system—such as the Yamaha
KX5 or KX76/88 keyboards—and the output of the QX21 1s driving a separate tone
generator such as the TX81Z. This enables the keyboard to “play” the tone generator
directly via the QX21 as shown in the following diagram.

When ON, this job prevents alteration of data residing in the QX21 memory (tracks
1 and 2, and the temporary buffer). The default mode is OFF. Call job C-5 by holding
the RESET button while pressing the JOB/STEP SIZE A/C selector 4 times. The
LED display will alternately read indicating that the MEMORY PROTECT job
IS active, and the currently selected mode. The —1 and +1 buttons turn MEMORY
PROTECT OFF and ON.

Activating this job forces the QX21 to function as a MIDI status monitor rather than
a sequencer. in other words, MIDI data received at the MIDI IN terminal will be
displayed in hexadecimal form on the QX21's LED display. This function is pati-
cularly handy for monitoring MIDI signal status in a MIDI misic system, trouble -
shooting, MIDI system research, etc. The default mode for this job is OFF.
Call job C-6 by holding the RESET button while pressing the JOB/STEP SIZE
A/C selector 5 times. The LED display will alternately read indicating that the
DISPLAY MIDI STATUS job has been called, and the currently selected mode.
Use the —1 and +1 buttons to turn the function OFF and ON.
= Normal QX21 operation.
= MIDI status monitor operation.
20
If ON is selected, press the RESET button to clear the LED display and begin op-
eration as a MIDI status monitor. Job C-6 must be recalled and set to OFF to resume
normal QX21 operation. If OFF is selected, pressing RESET returns to job A-1.
As we discovered in the Quantize section, above, the QX21 has a temporary buffer
Save Temporary memory. Executing this job swaps the contents of TRACK 1 and the temporary
Buffer buffer, recalling the temporary buffer data into TRACK 1, and saving the TRACK
1 data in the temporary buffer. In addition to allowing you to recall the original
(Job D-1) data after a quantize operation, the temporary buffer is also useful in a number of
editing situations. Suppose, for example, that you have a phrase which will occur
more than once during the course of a composition. This phrase can be created
and saved in the temporary buffer using the SAVE TEMPORARY BUFFER job. It
can then be recalled and chained onto or inserted into the data on TRACK 2 as
needed. Call job D-1 by holding the RESET button and pressing the JOB/STEP
SIZE B/D selector once. The LED display will read and the TRACK 1 indicator
will flash. Pressing the START button then actually executes the SAVE TEMPO-
RARY BUFFER job, or RESET to cancel.
This job makes it possible to delete a single MIDI channel from a multi-channel
Delete Channel recording (refer to “SEQUENCING MULTIPLE TONE GENERATORS” section). -
(Job D-2) Since material recorded on other MIDI channels is left intact, this function eliminates
the need to redo an entire recording if only one channel is not satisfactory.
Call job D-2 by holding the RESET button and pressing the JOB/STEP SIZE B/D
selector twice. The LED display will read [cc]. Then use the -1 and +1 buttons
to select the number of the MIDI channel to be deleted (1 ~ 16). Finally, press
the START button to delete the selected channel.
With this job it is possible to correct “off-time” notes entered in the real time record
Quantize (Job D-3) mode by forcing ali notes to fall on the nearest “quantize” unit. The available quantize
values are: 1/4, 1/6, 1/8, 1/12, 1/16 and 1/24 notes.
For example, if a phrase in which the smallest note length is 1/8 notes has been
entered in the real time record mode, and some of the notes are a little off-time—i.e.
the notes do not fall precisely on 1/8th measure increments—the phrase can be
quantized to 1/8 causing all the notes to fall into perfect time.
The QUANTIZE job can be used only on data which is on TRACK 1. First, call job amy,
D-3 by holding the RESET button and pressing the JOB/STEP SIZE B/D selector
3 times. The LED display will alternately read indicating that the QUANTIZE
job is active, and the currently selected value. Use the —1 and +1 buttons to select
the desired value. Pressing the START button then actually executes the QUANTIZE
job, or RESET to cancel. The quantized data is left on TRACK 1. To give you a second
chance just in case quantizing ruins your recording, the data is stored in the QX21's
temporary buffer memory prior to quantizing. The data in the temporary buffer can
be recalled to TRACK 1 using the SAVE TEMPORARY BUFFER job (job D-1)
described above.
NOTE:
The selected quantize value must be equal to or smaller than the smallest note
length contained in the data to be quantized, otherwise random omission of
notes or changes in note length may occur (thus the temporary buffer save
operation!).
21
Cassette Save/
Verify/Load
(Job D-4)
This job incorporates the cassette save, verify and load functions which permit you
to save your QX21 compositions on standard cassette tape and load them whenever
they are needed. To use the cassette interface, make sure that the cassette cable
is properly connected to the QX21's CASSETTE DIN connector and the cassette
recorder’s earphone and microphone connectors (see page 4).
To perform any cassette operation, it is first necessary to call the CASSETTE TAPE
job. Call job D-4 by holding the RESET button and pressing the JOB/STEP SIZE
B/D selector 4 times. The LED display will read indicating that the CASSETTE
TAPE job is active. Any of the three available cassette functions—LOAD, VERIFY
and SAVE—are then activated by pressing the corresponding button:
RECORD/LOAD, STOP/CONTINUE/VERIFY or START/SAVE. The three functions
will be covered separately below.
SAVE
This function saves the contents of the QX21 memory to cassette tape. First call
the CASSETTE TAPE job, start the cassette recorder running in the record mode,
then press the SAVE button. The LED display will read indicating that the SAVE
operation is being performed. The QX21 will beep once for each data block (256
bytes) which is saved. When the data has been saved the QX21 will automatically
revert to job A-1.
VERIFY
This function reads the data on the cassette tape and compares it to the data in
the QX21 memory, “verifying” that the preceding SAVE operation was accomplished
with no data errors. The VERIFY function should always be used to ensure the
integrity of your saved data. First, rewind the cassette tape to the beginning of
the file to be verified (the file you just saved). Call the CASSETTE TAPE job, start
the cassette recorder running in the play mode, then press the VERIFY button.
The LED display will read while the QX21 is searching for the beginning of
the file, to indicate that it is reading the file, and finally either If the data
is OK, or if the cassette data does not match the 0X21 memory data. The
QX21 will beep once for each data block (256 bytes) which is received. If an error
is encountered, try saving the memory contents again.
LOAD
This function lets you load a previously SAVEd file back into the QX21 memory
from a cassette tape. First, rewind the cassette tape to the beginning of the file
to be loaded, call the CASSETTE TAPE job, and press the LOAD button. The LED
display will read while the QX21 is searching for the beginning of the file,
to indicte that it is loading the file, and when the file has been loaded the QX21
will show ot. The 0X21 wili beep once for each data block (256 bytes) which
IS received.
NOTE:
1. if a data error is encountered during Verify or Load, the OX21 will sound
alternate high and low beeps.
2. Yamaha QX7 Digital Sequence Recorder cassette tape data is fully com-
patible with the QX21, and may be loaded and used with the QX21 as
described above.
22
This job specifies the MIDI channel to be used by the QX21 for MID! SYSTEM
Local Device EXCLUSIVE DATA communication, and permits dumping all QX21 track memory
Number data via the MIDI OUT terminal. Call job D-5 by holding the RESET button while
pressing the JOB/STEP SIZE B/D selector 5 times. The LED display will alternately
(Job D-5) read indicating that the LOCAL DEVICE NUMBER job is active, and the
currently selected channel number (normally 1). Use the —1 and +1 buttons to
select the desired MIDI channel number (1 through 16). Press the START button
while in this mode to initiate a bulk dump of the data contained in the currentiy
selected track. The LED display will read while track 1 is being dumped, and
[2] while track 2 is being dumped. Press RESET to return to job A-1.
NOTE:
Since QX7 Digital Sequence Recorder data is fully compatible with the 0X21,
QX7 data may be directly dumped onto the QX21, and vice versa.
This job provides an indication of how much free memory space is available for
Show Free Area further recording. |
(Job D-6) Call job D-6 by holding the RESET button and pressing the JOB/STEP SIZE B/D 4
selector 6 times. The LED display will alternately read and the remaining memory =
space as a number between 0 and 99. “99” indicates that nothing has been recorded
and the entire QX21 memory is available. The smaller the number the less memory
space remains. “0” indicates that the memory is full.
23
ERROR MESSAGES
The QX21 has a number of error messages it will flash at you (along with a warning “beep”) should something
go wrong. They are as followings:
E | MEMORY PROTECT

FCC INFORMATION
While the following statements are provided to comply
with FCC Regulations in the United States, the cor-
rective measures listed below are applicable world-
wide.
This series of Yamaha professional music equipment
uses frequencies that appear in the radio frequency
range and if installed in the immediate proximity of
some types of audio or video devices (within three
meters), interference may occur. This series of Yamaha
combo equipment have been type tested and found
to comply with the specifications set for a class B
computing device in accordance with those specifi-
cations listed in subpart J of part 15 of the FCC rules.
These rules are designed to provide a reasonable
measure of protection against such interference.
However, this does not guarantee that interference
will not occur. If your professional music equipment
should be suspected of causing interference with other
electronic devices, verification can be made by turning
your combo equipment off and on. If the interference
continues when your equipment is off, the equipment
is not the source of interference. If your equipment
does appear to be the source of the interference, you
should try to correct the situation by using one or
more of the following measures:
Relocate either the equipment or the electronic device
thatis being affected by the interference. Utilize power
outlets for the professional music equipment and the
device being affected that are on different branch
(circuit breaker or fuse) circuits, or install AC line “an,
filters.
In the case of radio or TV interference, relocate the
antenna or, if the antenna lead-in is 300 ohm ribbon
lead, change the lead-in to co-axial type cable.
If these corrective measures do not produce satisfac-
tory results, please contact your authorized Yamaha
professional products dealer for suggestions and/or
corrective measures.
if you cannot locate a franchised Yamaha professional
products dealer in your general area contact the pro-
fessional products Service Department, Yamaha Music
Corporation, 6600 Orangethorpe Ave., Buena Park,
CA 90620, U.S.A.
If for any reason, you should need additional infor-
mation relating to radio or TV interference, you may
find a booklet prepared by the Federa! Communi-
cations Commission helpful:
“How to identify and Resolve Radio — TV Interference
Problems”. This booklet is available from the U.S.
