Registrations
In addition to note and volume information sent on the Master Channels, the Rodgers
657/677 sends and receives MIDI information related to registrations. This information can
be used to control the stops and couplers of a separate Rodgers organ or, more commonly,
can be recorded by a sequencer (along with the note and volume information on the Master
Channels) and then recreated during playback.
Registration information is normally transmitted and received in the form of System
Exclusive (SysEx) messages. Every time there is a change in a stop or coupler, a SysEx
message is generated by the organ that gives the updated status of
all stops and couplers.
Each of these SysEx messages, then, communicates the status of the entire instrument.
If desired, the 657/677 can transmit Program Changes when combination pistons are pressed
on the organ. These messages only communicate which pistons are pressed, not the status of
stops and couplers. This is often useful when controlling the 657/677 from a remote MIDI
keyboard that sends Program Changes or from a different model of Rodgers organ. The
Program Changes are sent and received on one of the Master Channels.
System Exclusive messages normally provide the optimum control over registrations, both
those made by pressing pistons and those changed by hand. Factory default settings of both
Send and Receive are set to
Stops (System Exclusive messages). Available options are:
Stops , Pistons (Program Change messages), Stops and Pistons and Off .
Selecting MIDI Registration Settings
To change the Send or Receive status of Registration messages:
1. Press and hold the SET piston.
2. Rotate the Select knob clockwise until MIDI STOP CHANGE appears in the
display.
3. Rotate the Select knob to set the cursor to the Receive or Send parameter.
All Master Channels are reset to Send & Receive when the organ is powered off.

Registration settings are saved when the organ is turned off.
