good q!
currently, note length per pad will default to the arp duration set for that pad (hold K1 on the [arps] screen to toggle between bank and pad durations). this seemed like the best interim solution to avoid introducing a new performance gesture, especially one that couldn’t be recorded as played – the pattern recorders only capture pad presses, not releases, since one of the original core ideas for the sampler side of cheat codes was rooted in playing through slices as either 1-shots or loops.
the next update’s focus is going to be rewriting the pattern recorder mechanism, which will support pad presses as two discrete events (press and release), which will also offer a third mode for sample playback – momentary.
so, on the roadmap!
oh, that would be a fun instrument to sample into cheat codes! i always have a blast importing small riffs using instrument VSTs
