spirals

A circular sequencer for monome norns

Notes of the selected scale are spread around a circle. Points are drawn by rotating a set amount from the last point while moving outwards slightly and notes are triggered depending on where they land. Patterns repeat and change over time.

If you find any interesting patterns or have ideas of how this can be expanded then let me know!

Requirements

norns MIDI (optional) mx.samples (optional) grid (optional)

Documentation

E1 change current spiral K2 play / stop current spiral K3 toggle options -> E2 change option -> E3 change value K1 + K2 toggle lock sequence to the last X number of notes K1 + K3 toggle scale overlay

grid

spirals supports grid or midigrid to enable you to change current spiral, start/stop the current spiral and lock/unlock the current spiral.

on the bottom row the left 4 pads change the current spiral, the right most pad starts or stops the current spiral and one in from the right locks and unlocks the current spiral.

the top 6 rows fill up as notes play - the bottom right most lit pad is the most recent note.

press two pads to lock the current spiral to loop between those notes.

20210217:

20210220:

• If you have mx.samples installed it can now be used as the audio engine. Change the audio engine parameter and then select an instrument for each spiral. Make sure mx.samples is up to date before using it. If you don’t have it installed, restart after installing to ensure everything goes smoothly. Massive thanks to @infinitedigits for the library and help.

20210221:
