Thanks for the input. I'm hopefully getting to the end of the editor software development, which has taken far longer than I expected. I'm hoping we're in the home stretch now.
The Overture doesn't have any MIDI sending capabilities as of yet, but it shouldn't be hard to get it to send basic program changes. I'm not sure how much of a MIDI controller we can make out of it. The processor we used is pretty much just enough to do what it needs to do for the basic pedal functions, and not a lot more. But, I'll look at it and see what we can get it to do. The editor will bring firmware updating abilities, which is the first step.
