Registrations
In addition to note and volume information sent on the Master Channels, the Rodgers T787
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 which 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 T787 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 T787 from a remote MIDI
keyboard which 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
.
All Master Channels are reset to Send & Receive when the organ is powered off.
