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??
VCO fail? impossible to tune...

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