This set was performed with two rackmount machines running renoise and various VST plugins. We also were sending midi data to a lighting and video rig for fully sync’d visual effects.
There were a lot of techniques used overall, since everything was composed and performed in renoise.

One of the things we did live which might be of interest to other renoise users is we used the pattern scroll bar to move around in the song while it was playing. This caused short stuttered notes, and glitching effects.
