I've been playing with Koushion, the excellent new iPad step sequencer. No it's not pronounced "cushion"! You're meant to say the "i" but no idea how the rest of it's meant to sound. It's a Japanese word I think.
The drone is the Waldorf Blofeld, arpeggios from Korg MS2000BR, Access Virus C and Supernova II. Plus super-pads and subspace whistles from the Supernova. Recorded live with no overdubs.
