MOTM

Anybody have any thoughts on this? It may be premature, since I only have
one MOTM VCO built at the moment with two more on the way, but...

With multiple VCOs, I assume I'll take the keyboard CV, feed it into a jack
multiple, and plug the other, say three, cables into three VCOs.

At what point would such a setup need to be buffered? If I was driving, say,
ten VCOs, is an "oscillator driver/buffer" of some sort needed? Does the
average keyboard or MIDI/CV device put out enough current to drive a whole
bank of these babies without problems?

Am I demented for having such a worry?

Fair question.

I'd say probably most output stages can drive about 10-12 inputs, easy. 20,
probably.

There will be a point where the voltage each module "sees" will drop enough
to be audible, due to the parallel resistance of all the input summing
resistors.

But then a retune will fix you right up.

You are just heating up the 100Ks in the inputs more.
