Interesting, i already do something similar and never had a chance to check if it really works. Here is my code:

var buffer = dm.audio.createBuffer(1, 1, dm.samplerate); var source = dm.audio.createBufferSource();

source.buffer = buffer; source.connect(dm.audio.destination);

if (source.start) { source.start(0); } else { source.noteOn(0); }
