System exclusive messages (transmitted/recognized)
Each ‘sys ex’ (system exclusive) message largely looks the same. The first
7 bytes and the last byte are always the same. Only the ‘XX’ bytes vary. This
is the ‘sys ex message’ that Johannus generally uses: F0 00 4A 4F 48 41 53
XX F7 (hexadecimal).
Therefore, the ‘sys ex messages’ described below only mentions the value
of the 'XX' bytes and from which output these are transmitted.
All stops off
The ‘all stops off’ sys ex code is 7F. This sys ex code is transmitted through
the MIDI SEQ. output when the 0 button is pressed for a long time.
When an ‘all stops off’ sys ex code is received, all stops on the instrument
are switched off.
Pushbutton values
When a button is pressed, a sys ex code is transmitted with the value of the
button that is pressed (for example PP = 00 P = 01) through the MIDI MOD.
output.
These sys ex codes are only important when the Johannus sound module
CSM 128 is connected to your instrument.
Other MIDI codes (transmitted)
Press the 0 button for a few seconds to transmit the sys ex code, ‘all stops
off’ and all volume settings through the MIDI SEQ. output.
