So, here’s what I was doing: I had patched the top section so that an LFO patched into survey would pan my sound around in stereo
more about patching panning just in case it's helpful
In this patch I have high, low and centre of Sisters patched to left, right and offset on Cold Mac. Moving survey using the knob or CV will crossfade the left and right inputs into their corresponding outputs with opposite proportions, creating panning. I think, that anything into offset will be panned center regardless of knob or CV.
and then I realized that actually my crease out would give me a “creased” version of the LFO I had patched into survey (i.e. as the LFO crosses zero volts, the crease out jumps from +5V to -5V) which I could use to introduce a big change in my patch related to the LFO. (Haven’t found anything I liked yet though xD)
and what’s more, If I wanted to mix my stereo signal down to mono, say to modulate some part of my patch or run through W/, the mac output would give me exactly what I wanted—even if I were using the other parts of the module to make CV!
