I was able to get the MCU socketed it required using a non dust shielded alpha pot instead of the one provided.
While the v/octave may not be perfect it is much better than my MFOS quantizer, plus there are many different modes/scales supported, and the range is better than the MFOS one.
The V/octave is set internal to the MCU which contains both DAC and ADC. Potentially the MCU could be recoded.
For what it does and compared to what else is available I'm quite happy with mine.
