A parametric acid bassline explorer for Monome Norns.



tb-303 emulator should apply accent to received MIDI notes with a high velocity value (accent threshold adjustable) and slide to overlapping notes (“mono-legato” mode).

Other synths that have a mono-legato mode and allow velocity to modulate note volume and filter envelope modulation amount and/or cutoff may also produce interesting results.


Install from Maiden


Restart Norns to enable engine.

If you have another MIDI controller, I recommend starting by mapping the following parameters:
