We've got an 2600 at the school that has gradually gone out of tune, by this I mean all three oscillators.
I've tried triggering the CV with the native keyboard and a beatstep pro with identical results. Each oscillatoris slightly out of tune to each other, and they all seem to go about 30 cents per octave jump.
Seems like a scaling issue to me. I've read before that each oscillator has identical scaling components. Not sure how to go about fixing a problem like this so any help is appreciated.
