I just uploaded another FPD panel design for the Bi-N-Tic. My idea is
to use a CGS56 gate converter board to buffer the 4 counter outputs,
which I call SUB1-4 on the panel. These are +/-5V outputs. Internally
they go to the SUB IN selector switch, followed by the SUB LEVEL
attenuator and into IN 2 on the board. I didn't include an IN2 jack or
switch position. Instead I used panel space for the 4 SUB outputs plus
a linear FM input. I also added an FM CV attenuator pot.
It seems to me that it's worth treating this as a real VCO with top
quality parts. After all it is just like the CGS VCO core. The
addition of the SUB outputs allows it to be used just as a VCO if
desired. I tend to use a lot of square waves anyway. Having the 4
octave outs allows mixing them externally, too, possibly to be fed back
to the Bi-N-Tic input.
The cost of my panel design can be cut quite a bit if you remove all the
tic marks. I have to include them for myself, so as to match all the
others I have.
