Is there a fix / workaround for this?

There were some bugs in Safari on iOS 9.0-9.2. http://www.williammalone.com/posts/ios-9-web-audio-api-safari-mobile-issue/

I modified the examples to only init the audio context after the user presses a button. It seems maybe iOS Safari is trying to stop pages playing automatically. This sort of worked, in that the Basic one note example now works, but the MIDIPlayer example still stutters and makes noise after just a few notes. That might be what @greenSnot is describing.

Is there a fix for this? It is a huge issue. I am willing to offer up a bounty to see it fixed.

Which bit exactly @silverhawk184 ?

If you test on an IOS device (iPhone 6s+ v9.3.3) (the pirate tuna example) all the notes turn into a jumbled mess of pink noise within a few seconds. Then if you press pause, it slowly becomes discernible again before it stops.

Yes, the scheduling of all the WebAudio sources far in to the future (potentially 1000 nodes) is killing the iPad. That's a different issue that this one though which is that iOS Safari won't let you make any sound except in response to a user event.

Correct, but as posts #1 references the "noise", it is the cause of the issue being filed. It was then followed up with the autoplay issue.
