SynthModules

I have a Roland SC-7 (Sound Canvas) MIDI synth in a 1U MOTM format 
module that I use.  This version of the Sound Canvas has no user 
controls; everything is controlled by MIDI.  It makes it a pain to 
manually set program changes, etc.  I just wrote a little program that 
uses the PSIM input controls to provide manual controls for the SC-7.  
MIDI in is looped to MIDI out and I process the manual controls during 
MIDI idle states (e.g. no active commands).

In-1 selects 1 of the 16 GM families and is displayed in the top line 
of my LCD (Piano, Chromatic Percussion, Organ ... Sound Effects).

In-2 selects 1 of the 8 voices for each GM family and is displayed in 
the bottom line of my LCD. (Accoustic Grand, Bright Accoustic ... 
Clavi).

The program change is sent only to the last MIDI channel used so this 
can control different channels.

In-3 selects octave transpose and is displayed in the output LEDs.  
Out-1 indicates -2 octaves, Out-2 indicates -1 octave, etc.

Works pretty good.  Would even work better with the CVS display where 
I wouldn't have to abbreviate so much to fit the descriptions into 8 
characters. Those of you with a PSIM and wanting MIDI or a display 
should check out the ComputerVoltageSource page.  Boards will be 
available soon.
