Wow this opus modus tool looks super polished. I'd not mind paying for it, if it ran on windows! I've heard about other tools like this before ([1] for composition, [2] for synthesis, [3] for mind-blowing :-p) but somehow never heard about opus modus before. * Where did you learn about it? * Are there other similar prog-lang music production tools with similar level of polish? * Any cross-platform / Windows supported tools? -- unfortunately opus modus only runs on macs :-( 1: https://github.com/ctford/leipzig 2: https://github.com/overtone/overtone 3: https://extemporelang.github.io/

Not knowing about Leipzig[0], I've been trying to come up with my own representation of music in JS to work with the Web Audio API. My biggest puzzle so far is how to a) keep a rhythm and b) allow musical "blocks", which are indeterminate in length, to fit into this rhythm. I was thinking that these blocks would be pre-defined functions which represent different aspects of music (bassline, riff, etc.) which could be repeated and inserted at arbitrary time in the composition. If anyone is interested on working on this drop me a pm/comment (it's just for fun) [0]https://github.com/ctford/leipzig

I think this is a key thing to notice about Alda. It doesn't attempt to provide abstractions for things like keys, scales, or even measures and time signatures. It's more like writing Markdown: you already know what you want to write; it just gives you a way to represent it in a compact way and turn it into something you can hear back without having to reason too much about what you've written. I want Alda to be as close as possible to a sheet of staff paper that you can write notes on. MML is a very similar language in this regard. The idea is that it's up to the composer to write down the exact notes he/she wants, exactly how he/she wants them. I realize this is disappointing if you're looking for something with more abstractions, but on the bright side, I think there are some great languages out there that do exactly that. If you haven

't already, have a look at Music-Suite ( http://music-suite.github.io/docs/ref ) and Overtone ( http://overtone.github.io ), along with the Leipzig library, which adds functional programming abstractions for use with Overtone ( https://github.com/ctford/leipzig )
