MOTM

Douglas,

It's great to have you onboard the MOTM train. Sounds like you have a very
interesting design.

So how would you describe the sound of through-zero modulation in your
oscillator? Yamaha FMish? Does it significantly increase the tonal palette
available over conventional analog FM?

If so, would you be adverse to allowing Paul to add your design to the MOTM
arsenal as an alternative VCO module?
