The keyboard doesn't track on this one for some reason.

via the listing: "The unit turns on and makes sound but its only producing the same sound on all the keys. Even if you press different keys, they only produce the same single pitched tone. All the keys appear to be responding however.

So below are the list of functions that I was able to test and know that are working/responding.
- VCO, SUB OSC, NOISE
- All three WAVEFORMS and PWM slider.
- ENV-1
- VCA HOLD
- CUTOFF FREQ and RESONANCE
- NOISE WHITE / PINK
- HPF CUTOFF FREQ slider

These above seems fine, but everything else was basically unable to be tested and/or don't know if they work."
