Subject: [ModularSynthPanels] Bug panel -- decisions...

Maybe the question should be:
Which of the following do you want? --
1) 2U panel that uses only the PCB circuit
2) 5U panel that uses 2 PCBs plus user-built circuitry -- Child Tones
(Ring mods), Disturb CVs.

I think one problem is that there is different usage of terms -- tone,
woggle, ring mod, child tones. I am confused! Even the schematics are
varied in their usage.

The PCBs from Jan have the Ring Mod Out, which is the Ring Mod from the
PLL.

The two Child Tones are the Ring Modded Woggled Tones from two 'Bugs,
and the Ring Modded Smooth Tones from two 'Bugs.
To replicate these, it looks like a single XOR would do for each
channel, or the builder could use CGS RRMs, Yusynth ring mods,
1496-based designs on protoboard, whatever.

And for the Disturb Input, we could buffer an external CV, w/ that jack
normalled to the internal stepped CV. I have a buffer PCB that would
work for this, or a Tellun MUUB-2 could be used for both channels.
Richard Brewster fades between two Disturb CVs, one of which is
normalled to the stepped CV, which would be nice. To replicate this we
would each have to do something on prototype, or make Tellun MUUB-4
PCBs work.

Richard, Grant, anyone: If we just use a buffer for a single Disturb
CV, normalled to the internal stepped CV, would negative CVs hurt the
PLL?
Richard, is that rectification for protection, or for better external
CV action?

Feel free to correct me on any of the above.

So you see why this is a big panel question: to mod or not to mod? If
to mod, in what ways?

Option 3:
2U 'Bug as per Jan's PCB.
1U 'Bug buddy expansion panel for the dual buggers -- 2 Child Tone
Outs, Disturb CVs w/ attenuators.

My head hurts.
