TL;DR Melrōse is both a language and a tool to create and listen to music interactively, The language uses musical primitives (note, sequence, chord) and many functions (map, group, transpose) that can be used to create more complex patterns, loops and tr…

This script is an example that uses the Melrōse language to create your own drum beats.

1 2 3 4 5 6 7 8 9 bpm(90) s = sequence('c e g b') i = iterator( '(1 2) (3 4)', '(1 3) (2 4)', '1 (2 3) 4', '(1 4) (2 3)') m = resequence(i,s) l = loop(m,next(i)) 🎶 Play Using resequence you can compose a new sequence with index-based entries.

After watching Play With Your Rythm: Drum Patterns, I was inspired to program some of these patterns in Melrōse.
