The callback that was used in the synth object was only working for Chrome audio. I changed it to let it call the more general method.

The audio lib works with Safari but currently only on HTML pages. The SWF object is not correctly embedded in XHTML pages and thus the audio interface isn't available. Can anyone who know more then me about Flash have a look at that?


Some slight improvements:
- no need to execute the workspace every time, the synth object will be deserialized
- use morphic to for stepping
