Program changes (transmitted/recognized)
Organ stops: Depends on the number of stops and the sequence of stops.
MIDI stops (programmable): 1-128.
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 value of the 8th
byte varies. This is the
‘
sys ex message
’
that Johannus generally uses: F0
00 4A 4F 48 41 53 XX F7 (hexadecimal). The ‘sys ex messages’
described below only indicates the value of the 8th byte (XX) and the
output from which it is 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 piston 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 piston is pressed, a sys ex code is transmitted with the value of
the piston 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 piston 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
