Programming (PGM) mode of the device enables very easy programming of CR-78’s user
memories (patterns). After PGM mode is selected (with MODE switch), display shows info
about working mode change shortly and then the controller comes into programming mode.
After entering into programming mode, invitation for setting of CR-78 is shown on display .
Valid setting of CR-78 must be confirmed by NEXT button pressing. Now programming
procedure begins.
Length of programming step is displayed in upper row and actual position of programming is
displayed in lower row of display . Requested length of programming step (length of Beat) can
be selected with BEAT INCREMENT / DECREMENT buttons. Just selected length of
programming step is shown on display . Available Beats and their lengths in clock pulses (ticks) are listed in
table below:

Actual position is displayed in M:B:T (Measure : Beat : Tick) form. Starting position (after PGM mode is selected)
is always 1:01:00.
Pressing of WRITE INSTR button inserts drum instrument selected with “INSTRUMENT
SELECTOR“ selector on CR-78 panel onto actual position. Actual position is not changed when an
instrument is inserted so it is possible to insert more instruments (up to 4, ACCENT include) onto
the same position. It can be done if next instrument is selected with “INSTRUMENT SELECTOR“ selector on CR-
78 panel and then WRITE INSTR button is pressed repeatedly. Symbol of note [ ] is displayed in upper row
of display every time when the button is pressed. The controller doesn’t react during the symbol is displayed
– it is necessary to wait for blackout of the symbol before next pressing of a button.
Actual position is shifted one step ahead if NEXT button is pressed. Length of the step is
equal to number of clock pulses (Ticks) corresponded to duration of selected Beat (with BEAT
INCREMENT / DECREMENT buttons – see table 1). After the position is shifted, new
actual position is shown in lower row of display . Repeated pressing of NEXT button enables sequent
stepping – it is equivalent to insertion of a pause. Symbol of arrow [ ] is displayed in lower row of display
every time when the button is pressed. The controller doesn’t react during the symbol is displayed – it is
necessary to wait for blackout of the symbol before next pressing of a next button.

It is necessary to turn CR-78 to programming mode before start of CR-78’s memories programming. Some
controllers on CR-78’s panel must be set to following positions:
• Requested memory must be selected with “PROGRAM RHYTHM“ selector. The memory can be erased before
programming if necessary.
• “PROGRAM SWITCH“ must be in “MEMORY“ position.
• Requested (programmed) drum instrument must be selected with “INSTRUMENT SELECTOR“ rotary selector.
Note that all four user memories of CR-78 have fix length of two four-quarter measures. It is 96 clock pulses
(Ticks) – CR-78 uses 12 PPQN (Pulses per Quarter Note) resolution. When length of memory is exceeded during
programming procedure, clock pulses counting starts from 1:01:00 position repeatedly. This corresponds to
method of position indication on display .

25) Press NEXT button (on the controller) for continuing to next note. Display will show 2:03:00 position
(third quarter of second measure).
26) Store “CH” instrument (it stays selected from previous step) with WRITE INSTR button pressing (on the
controller).
27) Select “SD” with “INSTRUMENT SELECTOR“ (on CR-78 panel) and store the instrument into CR-78’s memory
with WRITE INSTR button pressing (on the controller).
28) Press NEXT button (on the controller) for continuing to next note. Display will show 2:04:00 position
(fourth quarter of second measure).
29) Select “CH” with “INSTRUMENT SELECTOR“ (on CR-78 panel) and store the instrument into CR-78’s memory
with WRITE INSTR button pressing (on the controller).
30) Now programming of CR-78 memory is finished. Turn “PROGRAM SWITCH“ switch on CR-78 panel to
“PLAY“ position.
31) Turn the controller to playback mode (MODE switch to “PLAY“ position).
32) CR-78 will replay newly programmed rhythm during next start of playback.
Any other rhythm can be programmed by similar way. The only limitation is, the shortest beat is 32
th
triplet and
32
th
note isn’t accessible. This limitation is given by CR-78 construction.
In some cases, this limitation can be get out by doubling of tempo during playback. It is enabled if
synchronization is INT or DIN-24 or DIN-48. But length of user memory is contracted to only one measure in
that case.

First, rewrite the rhythm for double-speed playback:
This rhythm can be programmed to CR-78 memory by method described above.
Set double tempo after the controller is turned back to playback mode:
• For internal synchronization (INT), set double tempo with BEAT INCREMENT / DECREMENT buttons
directly.
• For DIN-SYNC synchronization (DINxx), set half resolution of clock pulses than it is really transmitted from
clock source (set DIN-12 for synchronization source with PPQN = 24, set DIN-24 for source with PPQN = 48).

SEQUENCE OF PROGRAMMING IN REAL TIME SEQUENCE OF PROGRAMMING IN REAL TIMESEQUENCE OF PROGRAMMING IN REAL TIME
SEQUENCE OF PROGRAMMING IN REAL TIME
The controller enables real time programming of CR-78’s rhythms too. This programming method is described
in owner’s manual of CR-78 (in THE OPERATION OF THE PROGRAMMER SECTION chapter). The only difference
is that manual switch TS-1 described in the user manual is not used – it is replaced by WRITE INSTR button
on CR78-PGM controller.
The controller stays in playback working mode (PLAY). After setting of CR-78 (see above), tempo generator is
turned on with help of START / STOP button of the controller (if internal synchronization is selected) or
from MIDI or DIN-SYNC device (if MIDI or DIN synchronization is selected). Now instrument selected with
“INSTRUMENT SELECTOR“ on CR-78’s panel is written into CR-78’s memory every time PLAY INSTR button
on CR78-PGM controller is pressed.

DEVICE ADJUSTMENT DEVICE ADJUSTMENTDEVICE ADJUSTMENT
DEVICE ADJUSTMENT
The device enables user adjustment of length of pulses generated on START/STOP , WRITE and EXT CLK
outputs. Sometimes this can be necessary – if the CR-78 instrument doesn’t react correctly to Start / Stop
and Write commands or when programming steps in PGM mode or running in PLAY mode are irregular.
This is mostly caused by input circuits of the CR-78. The instrument is very old and some components alter their
parameters over time – especially electrolytic capacitors. In that case, longer START/STOP, WRITE and / or EXT
CLK pulses have to be used for such instrument.
To entry into programming mode, press WRITE INSTR button and hold it. Only then switch the device on
(connect power supply adapter to the device). Display shows first parameter value. Now, the WRITE INSTR
button can be released.
Remark:
Remark:Remark:
Remark: Adjustment of the pulse lengths is available only in versions of operating system 3.00 and higher. So
please check version of your firmware (see chapter 6.1) before you will try to change lengths of the pulses.
