While the line between consumer and professional is blurring, I see your
point. It's not like the early 80's when folks producing synth pop and
industrial in their bedrooms were stuck with these crappy mixers of asian
origin -- +4 is much more common in today's home studios. Anyway, the
difference between -10 and +4 as a voltage standard has more to do with the
inputs. You'll notice on most gear with selectable switches on the back
for each standard, that the switch has no effect on the outputs. +4 almost
always implies a balanced output.
Many unbalanced "-10dBu" synths and effects can produce outputs over
+13dBu, and most +4 gear can output +22dBu, or even +28dBu.

This is true.

Which leads to...

My Mini Moog has two output jacks -- one high, and one low. Perhaps the
Memory Moog has the same. I have no idea about the OSCar. Nor do I have a
120. Yet based on what you are saying, the output of these synths isn't
that hot, so in your case, you could make use of a pre-amp.
Perhaps most of my concern has to do with marketing. Although it literally
isn't my business, I still wouldn't want to see Paul lose money on a
module. I haven't had any trouble using my 110 or 410 (with the added 68K
resistor) directly with consumer gear like the TB-303, TR-909, MAM VF-11,
Lexicon Vortex, or Korg Prophecy. Correct me if I'm wrong, but couldn't
the 830 6*2 mixer be used as a "double pre-amp"?? What about the 130??
I am curious how a the Triple Pre-Amp fits onto 2U, and why it isn't a 1U
double pre-amp or a 2U quadruple pre-amp. What features does it have??
Does Moe have a panel layout?? Maybe if I saw the thing, its usefulness
would be more apparent.
