I tried my hand at some No-Input Mixing last week, using a battered old little Yamaha mixing desk I had lying around. Great fun! I hit record for my second patch, and ended up with this:
All source sound comes from the Mixer, and I ran it through my Eurorack for some filtering and FX. I managed to get an atmospheric, slightly claustrophobic feeling - you can hear several layers of different feedback loops all on top of each other, achieved by very careful working of the mixer’s EQ. Anyhow, hopefully someone might enjoy this!
