[sdiy] First C key name and MIDI note values of 32 keys church organ pedal board ?

[brianw]

I seem to recall that some synth modules do not respond to the full 128 Note range, or at least when they do respond they wrap to a repeated octave within their range.

I have not seen documentation of the limitations for various popular synths, but you might want to ensure that your pedal board does not transit a MIDI Note number that is so low that it ends up being out of range, especially given that you're already planning to separate the "stop" as separately programmable.

But as mentioned, you'll see other interpretations. What doesn't change is the frequency. The "octave number" is arbitrary depending where you begin.
