Hi,
I am modifying a synth keyboard with new pitch bend (PB) and mod wheel (MW) potentiometers. The existing pots are 10k and they must be special because they turn about 90 degrees and my ohmmeter shows they reach full range of a 10k pot. The new pots cannot rotate the full range either due to the mechanics of the device. The PB pot rotates about 90 degrees and the MW pot rotates about 45 degrees. Is there any way to modify the potentiometer circuit to get a wiper voltage output closer to full voltage range when I am only able to rotate the pots a small degree? Appreciate any ideas on this!
