Technical
Programming
The CR-78 can haz 4 patterns of 2 bars each (2x48 clock pulses).
Each pattern can consist of a total of 4 instruments.
Clever trick: the 5th instrument can de added to a pattern, by triggering it externally using the WRITE port during PLAY mode.
Connections
Back side of the Roland CR-78:
For external programming, you need 3 sockets: START/STOP, WRITE and EXT CLOCK
The WRITE and START/STOP input sockets need:
- an S-Trigger, which is nothing more than an on/off switch, so do not feed a 5V gate voltage into the socket.
- well actually you can feed 5V into the socket, for safety keep it 5V though.
The EXT CLOCK input socket needs:
-
12 pulses per quarter note (48 pulses for each whole 4/4 measure, 96 pulses for the 2 bars)
- between +5V and +15V
- a pulse of minimal 5 milliseconds
MIDI to CV
The "Kenton Pro Solo MkIII" can generate all the required signals from a standard MIDI signal. The unit converts MIDI data to the 3 needed CV signals.
When programming the Kenton to control the CR-78 with MIDI, program the following Ports:
- S-Trig
- AUX1
- AUX2
| CR-78 Port IN | Kenton Port OUT | Para | Val | Kenton setting |
| WRITE | S-TRIG | P16 | S__ | S-Trigger without pull up |
| START/STOP | AUX1 | P20 | Stt | Start/Stop Clock |
| CLOCK | AUX2 | P30 | CL1 | CLOCK1 |
| P60 | d2 | CLOCK1 => 12 ppqn | ||
| MIDI THRU | P90 | S24 | Set MIDI THRU port to DIN SYNC | |
| P92 | On | MIDI Continue = Start |
