From Konnakol to Live Coding

on YouTube ↗21m

" summary

Adapts TidalCycles (Haskell) and Strudel (JavaScript browser port) to encode Carnatic konnakol rhythms by adding a metrical tactus metadata field and a pure-value cache so patterns remain functional but expose beat-granularity. Implements stepwise tools: step expand, taper, stepcat and a polymetric join (plus inner/outer/squeeze joins) that align and rescale steps across cycles. Code runs live, simplifies earlier complex type-class hacks, and is used in a subsequent concert performance.
