Hi Gino!

OK - I Haven't finalized anything. Maybe now's the time and we can
draw on help from the community.

When Will and I were designing the panel, there was room for an extra
knob and Will got the idea to add a "mix" function.

In correspondence with Jurgen, he pointed out this could be
implemented by wiring "a 10K lin pot between the modulated and
un-modulated signal "- and adding "a 'Mixed output' which goes
directly to the wiper of the mix pot... but have the normal effect
output wired to a jack of its own (= your output jack)"

So this is the first possible implementation. 10K lin pot and mix
jack. Real straight-forward. Would the output of this mix be
inverted? I'm not sure. I'll have to check. Not that it necessarily
matters except to purists, I guess.

The second possible implementation is like the first, but involves
adding a buffer/inverter between the pot and the jack. By using a
Tellun MUUB2, two buffer/inverters could be provided - to buffer the
output and invert it to match the "normal effect output."

The third possible implementation is, I think, your idea - to use a
CGS mixer to accomplish the mix between the modulated and un-modulated
signal. This also sounds like a very good idea to me.

It should be noted that our design also has a "dry output." I can't
remember if this is part of Jurgen's original design or not, but
either way, it can be just a straight wiring of the input to the
output, I suppose, or it could involve a buffer/inverter too.

How had you thought to build this?

Anyway, beyond that, I just haven't gotten to any further development.

I'll begin work on a Dragonfly Alley page for the Triple Chorus. In
the process, I'll document all three of these possibilities. And I'll
post any of our collective ideas about implementation.

I suppose, in a strict sense, this discussion now goes beyond the
subject of Synth Panels. So maybe it really belongs on the MOTM forum
or something.

Ideas?

Thanks, Gino - thanks, guys

Bill
