I have been looking over Ken Stone's neat version of Electronotes VCO
Option #1. I was thinking how it could be put behind a MOTM style
panel. As Ken's note says, "This is one of those PCBs than can be
assembled in a number of different ways to suit the builder's panel
space or "maximum knobs" requirements." With this panel version the
waveshapers (1 chip) are omitted in favor of packing a nice VCO into a
1U panel space. The features are somewhat like the MOTM-310 VCO, but
there are two different frequency control inputs, both attenuated. The
FM input can be switched between the exponential FM DC input and the
linear FM AC input. One of the Serge-like reversible attenuators is
used for the CV input. Finally, one input jack serves a dual purpose,
being switched between SYNC and PWM. This panel is almost identical in
layout to my Mixer-Comparator, with 3 pots, two switches, and 6 jacks.
Not sure when I may get around to building these (I want two), but I'm
pretty keen on the concept. Just wanted to share my idea.
