strudel VS react-piano-roll

Interesting!

Similar note-based expression can be found on TidalCycles/Strudel. although it's not valid MIDI format anymore, you can use notation like c4, f3, and make them as "pattern". Samples are also supported in the same manner:

And in my project Glicol, I use only numbers in the seq node. So 60 means middle C. Underscore means rest.

TidalCycles doesn't. And you can try it online without installing anything.

Try evaluating `d1 $ s "bd sn"` to get a bass drum-snare drum rhythm going. Then `d1 $ s "bd*2 sn"` to kick the bass drum twice each loop instead of once. It can be extremely intuitive.

An easy way to experiment with this is via Strudel[1], a JS port that plays in-browser (annoyingly, works better with Chrome than Safari.)

It's recently gotten a great deal easier to play with thanks to Strudel, a JS variant.

One interesting feature of Tidalcycles is Euclidean Sequences, where various 'natural' ways of distributing X notes over Y durations are easily expressed:

It has a modular design so you can pick together different pieces to build into your project, if you're happy with AGPL: https://github.com/tidalcycles/strudel/
