makes it easy to create an instrument from audio samples. Pass
in an object which maps the note's pitch or midi value to the
url, then you can trigger the attack and release of that note
like other instruments. By automatically repitching the samples,
it is possible to play pitches which were not explicitly
included which can save loading time.
