Contol Pitch in semitone By usb midi cc#

[blh64]

Using 5.333333 instead of 5.33 might also help.

Even better, let the compiler give you the best possible number, use

Pitch_cc = ((128.0/24.0*semi_key)-1); 

And since the controlChange function takes a byte (0-255) value, round it

Pitch_cc = ((128.0/24.0*semi_key)-1)+0.5;
