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. At receiving an ‘all stops off’ sys ex code, 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 has been connected to the instrument.
Other MIDI codes (transmitted)
Press the 0 button to transmit the sys ex code, ‘all stops off’ and all volume
settings through the MIDI SEQ. output.
Sys ex code stops (Program Changes)
When a MIDI stop is switched on and off, an extra Program Change code
(preceded by the sys ex code 3F) is transmitted through the MIDI SEQ.
output, besides the usual Program Change. This is to distinguish between
a ‘normal’ organ stop and a MIDI stop before transmitting a module.
When a stop is switched on and off, the following codes are transmitted:
Organ stop:
Through MIDI SEQ.: CB XX
MIDI stop:
Through MIDI MOD.: CX XX.
Through MIDI SEQ.: CB XX and 3F CX XX
