Hi,

sure, you can never get a perfect sine out of an analog circuit, but the
AS VCO has a knob which shapes the wave from a sinusoid in the middle to
a triangular waveform at the edges. If you don't get the knob *exactly*
in the middle, the wave sounds very angular already. A dedicated sine
output might have been a better idea to keep more of the buzz out. This
said, voltage controlled waveshaping is definitely a feature which I
like most of the time. But I tend to want a fairly clear tone some
times, and this particular feature set makes it difficult to get. Even a
center-detent in the pot would have made it easier.

best,
D.
