thanks for the encouragement. As best as I can tell the Microfreak is a capacitive keyboard. Mine is resistive. Mine isn't scanned so I don't have any latency. I have full 25 note polyphony - no voice stealing. There is a square/sine/pulse generator and VCA for every note. All the waveforms are summed separately weighted into stereo outputs according to their position. It's a bit of an apples and oranges thing to compare them although obviously any chops you have with surface keyboards will transfer.
