At the time of recording this, (2019) i was using Ableton Live and a custom 6 channel surround plugin, i had 6 mini speakers set up in a rectangle in my studio. The use of this plugin created tracks that appear and disappear as they oscillate from speaker to speaker as this recording is only 2 channels of the full 6 channel set up.
It was a particularly lovely way to work as sometimes the tracks shudder as the oscillation is quite fast and other tracks meander into view and fade gradually. With Paul Bangash on guitar and pedals and Martin A. Smith on keyboard/synth. There is some real time manipulation of the oscillation times also.
