The set-up was as follows:
A Gameboy ASP running a couple of Nanoloop sequences > into a Boss PQ-4 parametric EQ, mono out > into a Boss PN-2 Panner (square-wave pan setting), stereo out > into a Boss RV-5 reverb (Gate setting), stereo out > into a Boss DD-6 digital delay (modified), stereo out > into a Mac G5 recording (via MOTU 828 mkII) into Soundtrack Pro. All realtime tweakery (mostly the PQ-4 + DD-6), no editing.
