MIDI expression

[Mathbob]

I have built key-to-MIDI boards as designed by Pete Stark [http://www.users.cloud9.net/~stark/midi.htm]. These are wonderful units that not only cost about half (or less) than commercial units, but are also much more flexible as the 68HC11 processor is user programmable.

My question is this: I know that MIDI note-on commands have a velocity code - which I could set if need be - to control swell (expression). But does software like MyOrgan or HW recognize other means expression control, such as the "control/controller" commands.

Through programmings, I can create any MIDI code needed; I just don't know what's needed.

Thanks, Bob

MyOrgan followup

Looks like HW uses MIDI continuous controller messages for swells. Is this true of MyOrgan?

Yes.
MyOrgan plays sample sets meant for HW version 1. This includes the Swell facility.

MyOrgan is able to control several expressive pedals (enclosure). You can select the midi message you want to do this task. It must be a control-change message (Bn), but any continuous controller is allowed. I often use volume message Bn 07 (for channel n) or expression message Bn 0B (0B in hexa = 11 decimal).
