The core idea of Nularseq is simple yet extremely powerful, which I hadn’t seen implemented anywhere else when I started working on it (since then I saw another Max for Live device implementing the same idea in a different way).
Nularseq allows the user to assign different sequences to various MIDI-capable virtual or physical instruments and perform with them in a way that’s not possible with other tools: they can conduct an entire virtual band or orchestra completely live without using a pre-recorded backing track, loops or even a metronome. To my knowledge, free-form improvisation that sounds like a complete band is not possible with any other means.
