WebFMSynth doesn't work well


(Core :: Web Audio, defect, P3)

Details doesn't work well in Firefox.

Clicking on the keyboard produces the wrong notes. This is bug 69787.

Running in a Firefox session with other apps open, we glitch a lot (dropouts). I guess this is because it produces audio on the main thread using a ScriptProcessorNode, though sometimes it seems to get stuck so there may be a bug there. It's a lot better when you run it in its own Firefox instance.

But even running in its own Firefox instance, there's crackling that sounds like clipping, so there might be another bug there.
We should try to repro once bug 1157137 lands. I haven't looked at the code, though.
Roc -- could you retry this, given bug 1157137 has landed and all the perf work we've done?  Thanks!

It's a lot better. However, often notes fail to play and a couple of times I got into a state where it seemed completely broken, so I think there are still bugs (though they could be app bugs).

Mass change P2->P3 to align with new Mozilla triage process.
