cynare question

cynare question

2006-10-27 by Tom Adam

I'm going to incorporate this modules and a drum sym in my 9090 project. Alas it turns out, due to the masive amount of panel space of the synare. That I'll have to drop a pot.

First of, I included a mixer in my 9090, so I have to bring the levels of the cgs modules to line levels to use them together with the 9090. But I also wanted to keep the posibility to use the cgs modules in my modular. So my initial idea was to use a switched jack followed by an attenuator. But then I started
looking at the r-gain of the filter section of the cynare. That got me wondering if I really need this volume pot. I'd like to know what the impact of this filter is on the volume, independent of the vca/vcf sequence. Or is it more interesting to leave the r-gain pot out?
Another posibility is to leave one of the 6 500k pots out. In this case, does it matter which one?

Back to soldering,

Tom

R-gain is usually a fixed resistor, or a preset trimmer. It is a
set-once-and-forget type control so you can adjust the filter output to suit
your system. Basically it is to compensate for variances in the transistors
used in the filter. It does not need to come out to the panel.

Ok, Checked it again, and I made a wrong reference.
I'm refering to what's described on the synthacon page as the level pads.

Cheers,
Tom

Correct reference. R-Gain replaces the level pads. It is doing the same
function.
