Do anyone know a fully working GM synth that use web midi API, i have tested two they seem to rely on same code base. But they really not support anything beyond channel, program, note on and note off.

A webmidi API GM synth or soundfont player , that support CC like modulation, pitchbend and effect 1 "reverb", effect 2 "chorus" would be nice. Sort of a webmidi API soundcanvas.

These are the two soundfont players i have found, "same or similar codebase".

//synth.Load('https://logue.github.io/smfplayer.js/wml2.html')
//synth.Load('http://imaya.github.io/demo/sf2.js/wml.html')

I probably will start program some sort of PCM "sample based" GM synth after christmas, but it would be nice if there already iwas something useful out there. The ones above just not sufficiently good.
