MOTM

Ken Stone's CGS VCO is a variant of the ASM1/Electronotes core design.  
The PCB offers many control and waveshaping features, but I built only 
the core, using high quality parts in the exponential converter.  The FM 
input has option switches for EXP/LIN and AC/DC, as the MOTM-300.  The 
pots are like the 310, except for the output mix.  There are separate 
saw and pulse outputs, sync and PWM inputs.  It fits into a 1U panel.  
It's like a 310 plus linear FM and hard sync.  Gee, could there be a 
MOTM-315 with these features?!  I'd buy two.  Would that be too many VCO?
