[sdiy] filter cutoff and pitch manipulator idea involving joysticks

[Rude 66]

if you're using an existing synth, how about hooking it up in place of the pitch bender? same idea.. korg even had standard sticks on their synths..

but pitch is more tricky. ideally i would like to have 4 or 5 pre-determined pitches, tuned to a certain key or scale, (i.e. 5 pots) , which are switched to vco cv input. which of the 5 pitches depends on the position on the value/position of the joystick pot. so in practice this would mean converting the varying voltage level from the pot into a fixed pitch (one of 5), which ever is closest. how could i do this?
