Oops, I forgot that the oscillator pitch also changes as you turn the
FM knob to exponentiate the waveform. So it's not very useful for
dynamic waveform modulation when you want to maintain a pitch. Sorry
about that. Thanks to geblinkoort for pointing this out.
Although, if you use the FM1 input with AC coupling then you can sort
of maintain the pitch. It will wiggle about as the FM1 knob changes
but the cap will block the DC offset and the pitch will return to
almost normal. I'm not sure if this is useful or not.
