After reading everyone's inputs for what is desired for a DIY/pc board only
(or module, but all in old fashioned through-hole technology) I've decided
to work on the SEM VCF with Voltage-Controlled Output Morphing.
For all you solder jockeys out there, it will be as complicated as the
MOTM-480 VCF. But with *more* parts. Yippee.
In order to take advantage of all it can do, it will have 6 panel controls
but 11 jacks. I plan to use a standard BR-1 bracket/MOTM pc board size
*unless* the layout goes south and won't fit. It will be *very* dense.
There will be 2 audio inputs, voltage-controlled resonance and
voltage-controlled output morphing (along with HP/BP/LP/Notch *fixed*
outputs). The MORPH sweeps between HP/BP/LP on a dedicated output.
Even though it uses 'vintage' op amps, I just checked Digikey/Mouser and
they have tons in stock. There are several LM13700 dual OTAs but again not
an issue.
