"Triangle and 8-Bit Delay" [mp3 removed]
"Pulse and Triangle and 8-Bit Freeze" [mp3 removed]
In these tracks MIDI piano roll notes trigger very basic modular synth patches and some very basic effects. Overtracking is used to stack tunes. These sound like chiptunes but they are just waveforms that are really...basic.
Update: Added a couple of bars to "Triangle and 8-Bit..." to make the middle section more coherent.
