• Welcome to the Pipe Organ Forum! This is a part of the open community Magle International Music Forums focused on pipe organs (also known as "church organs"), organists, organ music and related topics.

    This forum is intended to be a friendly place where technically advanced organists and beginners (or even non-organists) can feel comfortable having discussions and asking questions. We learn by reading and asking questions, and it is hoped that the beginners (or non-organists) will feel free to ask even the simplest questions, and that the more advanced organists will patiently answer these questions. On the other hand, we encourage complex, technical discussions of technique, music, organ-building, etc. The opinions and observations of a diverse group of people from around the world should prove to be interesting and stimulating to all of us.

    As pipe organ discussions can sometimes become lively, it should be pointed out that this is an open forum. Statements made here are the opinion of the poster, and not necessarily that of the forum itself, its administrator, or its moderators.

We strive to make this a friendly and informative forum for anyone interested in pipe organs and organ music.

MIDI expression


New member
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?


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).
