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

[Nathan Trites]

I'd expect that lowest note is going to vary by manufacturer to
manufacturer. You'd hope that professional digital organs from Viscount or
Crumar or anyone else would allow you to transpose those before sending it
out, but I'm sure there are many retrofitted organs or less comprehensive
ones that can't be adjusted.

I would include a transpose feature on the sound module to accommodate all
key range circumstances. That way you just need to make sure it works by
default with whatever is most popular and leave the rest of the work up to
users :)
