VCO fail? impossible to tune...

by elhambre on Mon Nov 12, 2012 12:02 pm

Hi, i buyed a non adafruit XoX almost builded, sourced a couple of components lost, tempo encoder and a bunch of resistors.

Finished, and everything is ok, sequencing and midi out works fine. But tuning is impossible, after trying a lot and with help of experimented people. Lower octave ranges from C to E, next from E to A, netx A to D...

So maybe is something not correct on the VCO,revisited all the resistors, transitors, diodes and seems to be ok. Any idea of what could happen??

Is the CV the correct 1V/octave? You can measure this directly at the CV output.
