Quarter note key selection

[smc]

Hi All,

I would like to modify the CV module to include a way to to detune any key either +50 or -50 cents. The keys which are nominated as quarter tone are performed via some DIN switches. The keys nominated as quarter tone must be performed in real time. Th player can select any combination of keys as being quarter tone in one instance and other combination in other instances. Again all quarter tone selection are performed via a set of DIN switches. The DIN switches (with LEDS) can be arranged like a keyboard layout to see what you have selected.

I would appreciated if someone can suggest or guide me on which part of the CV code should I modify (e.g a procedure call etc) in order to design something which resembles what I've described above.

Thank You.

Sam
