Exploring some ideas of using mono effects for stereo processing with the Eurorack Random*Source Serge Resonant EQ.

The Serge Resonant EQ is mono, so, usually, if you want to do stereo processing, you would need two of this (expensive) module to process your signal. With just a single module, though, if we mess with the two "comb" outputs, and consider mid/side processing, we can create some compelling stereo outputs.

0:00 Introduction, I/O overview
0:47 Mono signal in, mono signal out
1:10 Using the "comb" outputs to stereoize the signal
2:01 Mid/side processing the "comb" outs of a mono signal
3:14 Processing a stereo signal, side only
5:10 Processing a stereo signal, mid only
6:20 Changing the source material, side-only processing
9:16 Closing, next steps, mid-only processing
