2D polyphonic sequencer for grids.

I had this idea for a grid-based sequencer interface, but wasn’t sure if it would work until I built it. It takes some influence from other sequencers like loom and meadowphyics, but hopefully is also unique enough that folks find it inspiring.

The basic idea is that you “draw” sequencers across both axes. Sequencers can be placed vertically, horizontally, or diagonally, as long as they are straight lines.

Notes are stacked in 4ths vertically, and move in 2nds horizontally. Interesting patterns/melodies/polyrhythms result from sequencers of varying lengths interacting with one another.

Norns encoders will shift the sequencers across the x or y axis. You can also use LFOs (thanks again to @Justmat for the Lua LFOs) in the parameters to automate sequencer movement and get semi-generative results.

Each sequencer has an “intersect rule” which can be selected from the options page, and is triggered If two or more sequencers intersect at an active note. The rules are “octave”, “mute,” “reset self,” “reset others,” and “reset all”.

You can take up to 4 snapshots of the current state for storing and playing back sections that you like.

It currently uses Molly the Polly (thanks @markeats) as the internal synth engine, but you can also use it as a midi sequencer, or with Just Friends via crow.

This looks super cool! Can’t wait to give it a try.

really enjoying this @crim! thank you!
in a future update it would be great to save the “draw” sequences in the presets :wink:

Thanks! I’m glad you like it.

Yes I forgot about presets :upside_down_face:. I’ll add this to the roadmap.


:slight_smile: that would be nice and thanks for the script
