keyboard transpose

[mess]

hi,

I'm going to midify an old MG1 moog synth

so that I can use it both as a sound source

(controlled by external seq)

and as a midi keyboard controller for my

sampler...

Is it possible to implement transpose keys in

MIOS? I don't need the code itself, just some

pointers to get me on my way

I will be using midio128 or midibox64E

thank you very much

Hi Michaël,

A very flexible function which allows to tranpose octaves and semitones seperately can be found in the sequencer application (seq_event.inc, SEQ_EVNT_Transpose) -- but it's very compact and maybe too complicated to understand the basics.

Normaly, all what you have to do is to add the transpose value (which could also be negative) to the second byte of a Note event. And you need to write a short button handler which allows you to change this transpose value. And maybe also a routine which displays the value on screen.

Best Regards, Thorsten.

thank you very much for your help,

I'm going to try this as soon as

my examens are over...
