kreislauf

v0.3.3

Beat sequencing rund um den Kreis inspired very heavily by Pocket Operators and the work of Ethan Hein.

Kreislauf UI

Requirements

Norns or Fates.

Install/Update

Kreislauf can be installed via Maiden's project manager.

Overview

Patterns

Each pattern consists of 4 concentric sequencer rings:

channel 1 - kick (outermost),
channel 2 - snare
channel 3 - closed hi-hat
channel 4 - open hi-hat (innermost).

Beat/Notes

When a beat is added to a ring, it fires off a Midi* note when active (60 by default) to the corresponding channel. While, this script is design with intent to create drum patterns; each beat can have its note value adjusted allowing for melody/harmony constructs as well. Go wild...

*I've blindly implemented crow, but I have no idea if it works. Any crow users please let me know what bugs you find and I'll adjust.

Chaining

I also like the way Pocket Operators accommodate for chaining of beats so I incorporated the ability for multiple patterns with individual loop counts to be strung together. For single pattern beats be sure to keep loop count as Inf. if you want endless looping. If multiple patterns are create, the entire sequence will always loop.

Saving and Loading Sequences

Patterns can be saved and later recalled (along with accompanying PSET). A number of demo patterns of some staple beats is installed within ~/dust/data/kreislauf/patterns. LOAD and SAVE patterns from the params menu.
