Pre-programming a finite set of patterns and presets, then improvising their combination, balances reliability with spontaneity

Rather than programming everything live (high risk, high cognitive load) or pre-arranging an entire set (no improvisation), a middle strategy is to prepare a library of short patterns and saved device presets — perhaps 10 BeatStep Pro projects, a handful of SP-16 projects, and saved synth presets — and then decide their combination order, transitions, and layering spontaneously in performance. The creative act shifts from editing sequences live to selecting, combining, and transitioning between prepared building blocks. The musical variety comes from the large combinatorial space of combinations, not from live pattern editing.

Examples

Beatstep Pro: ~10 stored projects (beat + 1–2 melodies each). SP-16: matching project count. RE-303, SH-01A, Circuit Mono Station: saved presets. Performance = selecting which projects to layer and in what order, plus filter rides and breakdowns.

Assessment

Estimate the number of distinct combinations possible from 10 patterns on each of 3 sequencers. Then list two decisions a performer still makes live in this approach that determine the musical outcome.
