Not working #3

Ey bud, I get an error in the demo:

https://alda-lang.github.io/web-demo/#piano: a c c

Does the project still work?

The web demo is not actively maintained, although I'm happy to manage contributions if someone is interested in working on it.

It uses a very old version of the Alda parser which was based on a BNF grammar -- things work way differently now. I think to do things properly, we would want to convert alda-core (a Clojure library) to cljc so that we could target both Java at the command-line and JavaScript in the browser. That way, we could easily keep the ClojureScript version up-to-date instead of having to manage it as a separate library and manually update it each time the Clojure version changes.

I took a brief look, and it looks like the web demo has stopped working because the sound font files loaded by the MIDI.js library are no longer accessible. I saw in the JS console that there was a 404 trying to access https://raw.githubusercontent.com/gleitz/midi-js-soundfonts/master/FluidR3_GM/acoustic_grand_piano-ogg.js.

I fixed the incorrect instrument path, but this is indeed only a quick'n'dirty change. The underlying Alda library is still a ~2 years old build.

That got it working -- thanks for the quick fix, @ondras!
