A live modular rig can be built around spontaneous algorithmic sequencing or around pre-programmed banked sequences

There are two contrasting ways to build the sequencing core of a live techno rig. An improvisation-oriented system relies on algorithmic trigger sequencers with built-in patterns that auto-run from a clock, so it is very hard to go wrong and offers wide, spontaneous variety with little preparation. A prepared-oriented system instead uses several step sequencers run at different clock divisions plus a 303-style pitch sequencer whose pitch banks are programmed ahead of the set, trading spontaneity for specific, practised sequences and fills. Neither is superior; the choice matches the performer’s desired balance of surprise versus control, and the two approaches can be mixed.

Examples

Improv rig: algorithmic trigger sequencers plus a combiner auto-running the groove. Prepared rig: four step sequencers at divided clocks plus a 303-style sequencer with banked pitch patterns.
