Not being an expert on Serge I may confuse whatever I want! ;)

Never really read the specs, used or seen a Serge in real life it is
quite possible that I do confuse things up. I do however have a
schematic that I got sent to me with an Serge waveshaper.

I have to study these myself... meanwhile, I need to powerup the
Formant Waveform Processor that I have. The schem's is at Anders
Sponton's site.
