Rodgers 805C - Selecting MIDI Stop Change Settings

31
The MIDI Stop Change menu item allows the organist to control the transmission and reception of
System Exclusive (SysEx) Stop Control messages and Piston Program Change messages. Settings in this
menu are saved when the organ is turned off.
Note: Piston Program Change messages are transmitted and received on the organ Master Channels
and should not be confused with the Program Change messages used to select sounds from MIDI coupler
pistons.
 Selecting MIDI Stop Change Settings
1. Press and hold the SET piston, then turn the Select Knob clockwise (right) to “MIDI STOP
CHANGE”.
2. Turn the Select Knob to choose “RCV” or “SEND”.
3. Rotate the Alpha Dial to select the following options.
The Receive Field (“RCV”) has four positions:
“OFF”
Console ignores both SysEx and Program Changes
“STP”
Console receives only SysEx messages
“PST”
Console receives only Piston Program Changes
“S&P”
Console receives both SysEx and Program Changes
The Send Field (“SEND”) has the same four positions:
“OFF”
Console does not send either SysEx or Program Changes
“STP”
Console sends only SysEx messages
“PST”
Console sends only Piston Program Changes
“S&P”
Console sends both SysEx and Program Changes
Program Changes 1-10 on any Master Channel will activate the organ General Pistons of like number.
Program Change 20 on any Master Channel will activate the organ’s General Cancel piston. Program
Changes 21-25 on any Master Channel will activate the organ Divisional Pistons for the division
corresponding to that Master Channel.

the Receive Field (“RCV”) of the MIDI Stop Change menu.
