Here’s his explanation of the technical details:
I use 5 tracks of which 4 of them uses the Cirklons CVIO outputs and the Minimoog Voyager uses a MIDI output. The music starts with a sequence on the Rob Hordijk OSC HRM driven by a Synthesizers.com Q109 which is joined by a sequence on the Minimoog Voyager. After that sequences on the Synthesizers.com and the Moog Prodigy are joining and now and than a sequence on the Yamaha CS-30L can be heard.
