I have yet to actually receive my Norns, but I’m already bursting with ideas about what to do with it! If I can get my hands on a Crow, I’d really like to build a sequencer/LFO tool which works based on orbital mechanics.
Specifically, I’ve been interested in the mathematical dynamics of elliptical orbits for a long time, and Crow is kind of perfect for exploring this - four outputs means I can have three bodies, form lines between each pair, and output the angles between each of them as well as the area of the triangle they form. These produce deterministic but interesting waveforms; for example, here’s the area swept out by three bodies in circular orbits at various resonances:
It’s kind of like a wavefolder.
This becomes much more interesting for sequencing when we consider sampling, or latching, this waveform at intervals. Regular intervals, especially prime number ratios, give basic not-quite-repeating melodies:
More interesting still, though, is what happens when we sample the system based on the system itself, by only taking a new value at the time when any two bodies are at their closest or furthest point from one another:
(here, systems of circular bodies with ratios of 7/11/13 and 7/11/15). These are complex, interesting patterns, which repeat perfectly after a period of time and include naturalistic elements of performance, like portamento or glide. Quantizing to a scale when latched preserves musicality.
Obviously, these are just very basic plots I worked out in a simple Python script, but I hope to replicate a similar idea with elliptical orbits and proper quantization when my Norns arrives. I would love to hear what the Lines community thinks of the idea!
