[sdiy] Akai VX600

[Christoph Itzek]

hi!

i have two problems with my vx 600: the first voice of my vx 600 sounds very low and when i play a sound with square-wave and modulate the pulsewide i hear on some positions (of the pulsewide) nothing. the second problem i have is the calibration. if i want to calibrate the synth the vx 600 crashes.
first i have checked the voice cards an they are all ok. the next thing i have checked were the ssm3200 and they were not all ok. but the ssm2300 are very expensive, so my question is, if i could use normal 4051 cmos ics? replacing the ssm2300 ics would solve the calibration problem. but i don't know what i can do with the voice i can't nearly hear. anyone has any idea?

thanks,
christoph
