I should note that your software design will be significantly
different depending on whether you plan to work with MIDI only (i.e.
no interactions with an audio interface at all, no synthesis or audio
processing) or with audio and MIDI. As Brian notes, in the first case
you can just read and write MIDI event timestamps. In the latter case,
the audio interface clock is your master reference and most
interesting things will happen in the callback that is executed on
your behalf.
