What back end code have you integrated this with? Have you tried "flocking"? http://flockingjs.org/

(I have not, I'm just wondering about somebody else's experience with this sort of thing in JS)

I'm still pretty new to this (modern computer synthesis). I had a couple electronic music (synthesis) classes back in the day, but that day was back in the late 80s. We didn't even have any digital equipment the first time I took the class - it was analog gear with literal patch cords between LFOs, envelope generators, oscillators, filters and such. The second time we actually had some digital stuff to do FM and sampling layers.

There's no back end code used with this (assuming you mean server side). I've never tried flocking but it looks interesting. The library I wrote, MidiPlayerJS, just emits JSON events and in my demo I'm feeding those into a sound font library (https://github.com/danigb/soundfont-player). But my thought was to switch that out for this singing synth library and see what kind of sounds it can produce.

I don't know how to inform this author with the issue with 404 when try to load soundfont player.

You could submit an issue on the repo https://github.com/gleitz/midi-js-soundfonts/

Sorry about the confusion. By "back end" I meant the tone generator(s) that your "sequencer" (?) is calling.

Oh, by default the library doesn't implement any tone generator. But, in my demo (http://grimmdude.com/MidiPlayerJS/) I'm using https://github.com/danigb/soundfont-player to generate the sounds.

Thanks! And that would be awesome, definitely interested in that. MidiPlayerJS looks great. Let's try it out and see what we can make happen!

Looks cool! Combine this with Web MIDI and you could make a reasonable DAW!

Thanks for posting this!
