Quadraphonic recording and mix
I once was a professional (mostly classical music) sound engineer, musican, composer. Now I'm returning to music ... electronic music composition.. I have a large (mostly) Buchla synthesizer system which has quadraphonic mixing (front-left, front-right, rear-left, rear-right ) with full panning ablitity, reverb etc.. (why doen't my "Enter" key work here?) ...
