You can do that in the environnement :
You test if it is a keyshift
If yes you make a transformer that will convert the velocity value to a CC 1 0, or CC 1 50 or CC 1 127
If you cannot manage, send me a PM with yor email I will send you screen copies
Ah, thanks! That's sounds not too difficult.
But then you'd need a different environment for every keysswitch octave?
