idea with this VCO design was to made a very "musical"
and warm module like ASM1 VCOs but with a much better stability
and more vwaveform outputs
prototype picture (was not fitted with the Hard Sync stage
at this time...)
the core of the ASM1/Electronotes VCO, but with an improved
"ultra stable" CV expo stage and wave shapers
to get Triangle and sine waveforms from the saw output...
The pcb has been
routed to get best perfs on a single side pcb...
This VCO sound
as good as the Electronote /ASM1 VCO ... Normal somewhere
because it is the same core but with a "slightly"
better stability :)
