strudel VS Velato

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/

Hi, I'm the creator of Velato. I will be reworking the website to include more examples later this year. In the mean time, the latest version of the compiler is on github: https://github.com/rottytooth/Velato

No one has yet written a quine although I would love to see one -- perhaps outputting its representation in lilypond format.

In 2009, I made Velato, an esolang where code is written in pitch values (https://github.com/rottytooth/Velato) encoded as MIDI files. So sort of the opposite of writing algorithmic music (where the human programmer writes music to satisfy conditions of the program). Before switching to LilyPond, I'd used GUIDO with a GUIDO-to-MIDI generator, but it was always awkward. Part of the challenge is that notes can be sounded simultaneously to make the score work better musically, but still need to appear in the correct sequence in the MIDI file for the program to succeed; something that LilyPond handles correctly. There's a transparency to how LilyPond functions that is not always there with programs that try to be "helpful" and clean-up or rearrange information.
