To make it clearer I’m working on a MIDI module that will produce
Pipe organ pipe sounds from incoming MIDI notes from a separate pedal MIDI controller.
My pedal board starts with the lowest C note value of 36 deci (0x24).
This module will itself generate (selected tabs on the unit)
6 separate and mixable 1, 2, 4, 8, 16, 32 foot pipe lengths sounds (6 separate oscillators).
So an incoming MIDI note will trigger the pipe organ sound
But the MIDI note itself will not decide ‘which’ stops have been selected on the unit.
So.. The design process is almost done but the first MIDI C note offset has to be found
and put in my code.. It doesn’t matter really but I don’t want all the unit
to respond one octave higher or lower from the ‘normal’ incoming MIDI notes.
Hope I’m clearer now..
So, The lowest C key MIDI note value on a pipe organ pedal board ?

I think you need to specify both the keyboard (or pedal) key AND the pipe's stop length (32', 16', 8' etc.) to know the corresponding note.

The pedal board starts with a C key then goes up 2 octaves and a half to the final G key.

But I cannot find what would be the MIDI first C key note value..

C0, C1, C2 ?? and what is the MIDI note value of it ?

I have a MIDI controller keyboard which has 36 (0x24) as the first C key MIDI note value.

Read with MIDI-OX MIDI utility program..

So… Any clue for the name and MIDI note value for the first C key ?

Thanks !
