Clear isLoaded flag in setTune

[rcbilson]

I was attempting to update a synth controller in the background by running something like

synthControl.setTune(visualObj, false);

However, after I played the tune once any further calls to setTune would have no effect on the synth controller. This is because the isLoaded flag is not cleared by setTune, and when userAction is false the isLoaded flag causes the deferred call to go (in runWhenReady) to be skipped.

Solution: clear the isLoaded flag in setTune.

I'll look at this in a couple weeks. This can be tricky - browsers really want audio to be manipulated after a user interaction. I would suggest having a global click handler and starting your audio processing after the user has interacted with the page

I've had to go through a bunch of hoops to get audio to place in my client apps. In particular, iOS can be really finicky. Code that runs on Safari on OSX sometimes doesn't run on Safari iOS.

Anyway, make sure you test on iPhone!
