INTRODUCTION
Congratulations on your purchase of a Yamaha QX7 Digital Sequence Recorder! Your
QX7 Digital Sequence Recorder offers high-performance 2-track digital sequencing in
any MIDI-based digital music system. The QX7 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. What you play
will be reproduced exactly. 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 DX7 Digital
Programmable Algorithm Synthesizer and a TX7 FM expander — letting you sequence
more than one voice at a time. Further, a range of useful editing and other control functions
let 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 QX7 Digital Seguence Recorder can give you virtually unlimited capability for cre-
ative, digital music production.
IMPORTANT | D
This manual is organized in tutorial form. Therefore, in order to fully understand all aspects
of operating the QX7, we urge you to go through the manual and try out each operation
as it is described.

BASIC RECORDING & EDITING PROCEDURES
Real time and step recording with the QX7 are remarkably simple procedures. But before you try recording anything,
make sure that the MIDI OUT from your keyboard is connected to the QX7 MID! IN terminal, and that the MIDI
OUT from the QX7 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 QX7 YOU WILL ALWAYS RECORD ON TRACK 1.
— Assuming that you are just starting and that nothing has been recorded in the QX7,
Real Time Recording both TRACK LEDs will be out, as will the RECORD and START LEDs, and job
| ( Job A-1 ) A-1 (REALTIME REC) on the job lists will be selected. Set the TEMPO control
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 QX7 will give you a two-measure
count in: the metronome will beep 8 times (if 4/4 time, the default time signature, р
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.
NOTE:
The default time signature for real time and step recording is 4/4. Other time
sighature can be selected using the Beats/Measure job described in the
METRONOME/-TIMING CONTROL FUNCTIONS section on page 13.
— — — The ERASE “job” lets you erase all of track 1, or all track 1 data following a specified €
Erase (Job B-4) 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
the number of the currently selected measure or the end marking [JC]. You can
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, scroil 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 QX7 will automatically return to the stop
mode and job A-1 will be selected.

Recorded material can be automatically repeated from 1 to 99 times by setting the
REPEAT Job (job A-4). First, call the REPEAT ¡ob by pressing the JOB/STEP
SIZE A/C selector 3 times (LEDs “A” and “4” will be lit). The LED display will
now alternately display [-], indicating that the REPEAT job has been called, and
indicating that REPEAT is OFF. Press the +1 button once to turn REPEAT
ON ([an]) for endless repeat. Subsequent presses on the +1 button select 2, 3,
4....99 repeats. The —1 button can be used to scroll backwards through the REPEAT
numbers, and turn REPEAT OFF if desired. Of course, the +1 and -1 buttons may
be held to scroll quickly through the REPEAT numbers. Once the desired number
of repeats has been set you can return to job A-1 using the JOB/STEP SIZE A/C
selector, or simply by pressing the RESET button.
Overdubbing—recording one track over another—on the QX7 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. Basicaliy, 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 EC. Execute the EXCHANGE job by pressing
the START button. You can cancel the EXCHANGE job prior to executing by
pressing RESET. The material you recorded on TRACK 1 will now 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 or the other. Pressing the TRACK
button alternates between the ON and OFF modes: LED ON = track ON.
This job is oniy 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 LEQ display will read
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.
Insert (Job B-5)
Delete Measure
(Job B-6)
Chain (Job B-2)
Step Recording
This job allows material recorded on TRACK 1 to be inserted anywhere in TRACK
2. Suppose that you have recorded and overdubbed eight measures of music, and
that TRACK DOWN has been used so that all data now resides on TRACK 2. You
can now add a few bars between measures 4 and 5 of the TRACK 2 data in the
following way:
Record the material to be inserted on TRACK 1, then call the INSERT job by pressing
the JOB/STEP SIZE B/D selector 5 times (LEDs “B” and “5” will be lit). The LED
display will now alternately read indicating that the INSERT job is active, and
the currently selected measure number. Use the —1 and +1 buttons to scroll to
the measure immediately following the insert point (.e. the new material will be
inserted prior to the seiected measure). Press START to execute the insert, or RESET
to cancel. The insert material recorded on TRACK 1 is not erased when the INSERT
job is executed.
This job makes it possible to delete any specified measure on TRACK 1. Simply
call the DELETE job by pressing the JOB/STEP SIZE B/D selector 6 times from
the stop mode (LEDs "B” and “6” on the job list will be lit). The LED display will
now alternately read indicating that the DELETE job is active, and the currently
selected measure number. Select the TRACK 1 measure to be deleted using the
—1 and +1 buttons, then execute the DELETE by pressing START (or cancel by
pressing RESET).
The CHAIN job appends the data on TRACK 1 onto the end of TRACK 2. Cail the
CHAIN job by pressing the JOB/STEP SIZE B/D selector twice from job A-1 (LEDs
“B” and “2” will be lit). The LED display will read indicating that the CHAIN
job, is active. Press the START button to execute the CHAIN job, or press RESET
to cancel. The data on TRACK 1 is not erased.
In the step recording mode, notes, chords and rests are input one at a time from
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 fight, 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 alread-
y-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 = 1/16 note.
A-2 = 1/32 note.
A-3 = 1/64 note.
A-4 = 1/16 note.
A-5 = 1/8 note tripiet.
A-6 = 1/4 note tripiet.
B-1 = 1/8 note. .
B-2 = 1/4 note.
B-3 = 1/2 note.
B-4 = 1/16 note with 100% gate time.
B-5 = 1/8 note with 100% gate time.
B-6 = 1/4 note with 100% gate time. -

STOPISTART
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 QX7 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.
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 wiil be entered. The —1 button
can be used 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 TIE 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.
A footswitch such as the Yamaha FC4 or FC5 plugged into the rear-panel FOOT
SW jack can be used to activate the OX7's record/play START and STOP functions.
If the footswitch is pressed while the QX7 is in the normal stop mode, playback
will begin. Press the footswitch a second time to stop playback. if the QX7 is in
the record standby mode (RECORD indicator ON), however, pressing the footswitch
will begin recording. Press the footswitch a second time to stop recording.

Tone Generators which is to be played by a different voice. Since the data for all voices is output
from the QX7's single MIDI OUT terminal, the tone generators used must be
“daisy-chained” together using their MIDI THROUGH terminals. A practical

A Multiple Tone Generator System
— This job sets the MIDI channel number for material recorded in either the real time
MIDI Channel or step recording modes. The power-on default mode is that the. QX7 records оп
Number all channels so that any material recorded will sequence a tone generator set to
receive on any channel. To independently sequence different tone generators,
(Job A-6) 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 exampie, in a simple system using a DX7 and one TX7 FM expander, the DX7
11
- receives only on channel 1, so the TX7 should be set to receive on channel 2. First
you might record a bass line with the QX7 RECORDING MIDI CHANNEL set to
1, and then a piano part with the RECORDING MIDE CHANNEL set to 2. if your
DX7 is then set to play a bass voice and the TX7 a piano voice, the respective parts
will be played by the appropriate voices when the QX7 is STARTed.
To set the QX7 RECORDING MIDI CHANNEL, first call job A-6 (you should know
how by now). The LED display will alternately read lc A] indicating that the MIDI
job is active, and [5] 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 — 2 = 3..... > 16. Press RESET to return to job A-1 one 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.

Press RESET to return to the job À-1 once the desired mode has been selected.
Normally, the QX7 is synchronized to its internal clock signal, the speed of which
is controlled using the TEMPO control. In some applications, however, the QX7
can be synchronized to an external MIDI clock signal received at the MIDI IN
terminal. It might, for example, be useful to synchronize QX7 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 control is made using the
CLOCK job. Cail 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:
INTERNAL CLOCK
EXTERNAL CLOCK
Press RESET to return to job A-1 once the desired mode has been selected.

When the INTERNAL clock mode is selected, note resolution is 1/384
measure. When EXTERNAL is selected, note resolution is 1/96 measure.
The QX7 record/playback START and STOP functions can be activated
via the QX7's START and STOP buttons, a footswitch connected to the
QX7’s rear-panel footswitch jack, or by an external MIDI START/STOP
signal received at the MIDI IN terminal, whether the QX7 is in the IN-
TERNAL or EXTERNAL clock mode.

UTILITY FUNCTIONS
All the QX7's utility functions are contained within job lists C and D, which are not listed on the front panel but
are given on the QX7 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

This function should be turned ON when the OX7 is used in a system in which
the recording keyboard has no internal tone generation system—such as the Yamaha
KX1 or KX5 performance keyboards-—and the output of the OX7 is driving a separate
voice generator such as the TX7. This enables the keyboard to “play” the tone
generator directiy via the QX7 as shown in the following diagram.

‘ Quantize (Job D-1 )
+
With this job it is possible to correct “off-time” notes entered in the real time record
mode by forcing all 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
16

Buffer
(Job D-2)

Verify/Load
(Job D-3)
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 io | |
D-1 by holding the RESET button and pressing the JOB/STEP SIZE B/D selector :
once. The LED display will alternately read [95] t| 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 QX7’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- 2) described below.
NOTE:
The selected quantize value must be equal to or smailer 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!).
As we discovered in the Quantize section, above, the QX7 has a temporary buffer ;
memory. Executing this job swaps the contents of TRACK 1 and the temporary :
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 recal! the original |
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. |t
can then be recalled and chained onto or inserted into the data on TRACK 2 as
needed. Call job D-2 by holding the RESET button and pressing the JOB/STEP
SIZE B/D selector twice. The LED display wili 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 incorporates the cassette save, verify and load functions which permit you
to save your QX7 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 OX7'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 cali the CASSETTE TAPE
job. Call job D-3 by holding the RESET button and pressing the JOB/STEP SIZE
B/D selector 3 times. The LED display will read [£ P| 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 QX7 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. When the data has been saved the QX7 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 QX7 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 QX7 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 QX7 memory data. If an error
is encountered, try saving the memory contents again.
LOAD
This function lets you load a previously SAVEd file back into the QX7 memory from
à 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 OX7 is searching for the beginning of the file, to indicte
that it is loading the file, and when the file has been loaded the OX7 will automatically
return to job A-1.
When ON, this job prevents alteration of data residing in the QX7 memory (tracks
1 and 2, and the temporary buffer). The default mode is OFF. Call job D-4 by
holding the RESET button while pressing the JOB/STEP SIZE B/D 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.

Press RESET to return to job A-1 after selection. If you attempt to RECORD, TRACK
DOWN, CHAIN, EXCHANGE, ERASE, or perform any other memory-altering
function while MEMORY PROTECT is ON, the QX7 will respond with (“memory
protected display) and issue a warning “beep”.
This job specifies the MIDI channel to be used by the QX7 for MIDI SYSTEM
EXCLUSIVE DATA communication, and permits dumping all QX7 track memory
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
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 currently
selected track. The LED display will read while track 1 is being dumped, and
while track 2 is being dumped. Press RESET to return to job A-1.
Activating this job forces the QX7 to function as a MIDI status monitor rather than
a sequencer. In other words, MIDI data received at the MID! IN terminal will be
displayed in hexadecimal form on the QX7's LED display. This function is paticularly
handy for monitoring MIDI signal status in a MIDI misic system, troubleshooting,
MIDI system research, etc. The default mode for this job is OFF.
Call job D-6 by holding the RESET button while pressing the JOB/STEP SIZE
B/D selector 6 times. The LED display will alternately read indicating that the
DISPLAY MIDI STATUS job has been called, and the currently selected mode.
