spirals

A circular sequencer

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! Things I’m thinking about include:

  • Multiple spirals - either playing at the same time or cycling between them
  • Adding randomness to the rotation of the next point or maybe a chance of jumping a rotation and going on to the next
  • Ability to change something as the radius increases - rotation amount or filter frequency

Requirements

norns
MIDI (optional)

That’s great! Would it be possible to make 2 spirals? With different tempos and maybe scales too? Or - the ability to switch notes to chords? Just thinking out loud :slight_smile:

Ok added a chord mode for midi and engine output. I’m not too sure about crow but if someone has an example or wants to send a pull request then I’ll add it.

It’s just adding the 3rd and 5th in the current scale which I think is right but my music theory knowledge is almost non-existent so let me know if I’ve done something stupid :slightly_smiling_face:.

Multiple spirals might have to wait until I have a bit more time. Just started working on something new :face_with_monocle:

@tomw
a bit of a spin with Spirals for last night’s session…
it was controlling Buchla Easel Command.
also running OOOOOO and Cheat Codes 2.

so one of the things i did for last night’s session was to feed the Rotation feature in Spirals a MIDI S&H LFO from a MIDI PAL. seen HERE

would it be possible to add LFOs to the script?
