RE: [motm] voltage sauce !

2001-01-05 by Brousseau, Paul E (Paul)

I think (oh dear, not again) that you want to stick to +/-5V... or maybe
0-10V.  I don't think you want a full 20V swing.  The VCO outputs +/-5V, and
the EG generates 0-+5V and 0 to -5V.

I think you might want to use an op-amp (or rather, a quad op-amp) to
isolate yourself from the power supply.  Call it a hunch.

While you're at it, can you hickory smoke your voltage sauce?  It gives it a
more vintage flavor... <grin>
