Depending on what your overall goal is, it might be easier to use the software
MIDI synthesizer instead of computing the samples yourself— if you want a
bandlimited start and end, or even a music-like attack/decay/release envelope
or a spectrum more complicated than a pure sine wave, using something like the
AVMIDIPlayer class might free you from a bunch of realtime requirements and
bookkeeping.
(On the other hand, I’ve never tried using it, so I don’t know if its simple
API hides a well of frustration.)
