thats the only solution :)

but keep in mind that, just as with audio, JACK is "encouraging" "RT
design" in which you do the work associated with a particular audible
time as close to that time as possible. of course, this doesn't apply
to playback of MIDI from disk, but if you're doing algorithmic
composition, the long term goal is to encourage people to write the
same that they do with audio synthesis: JACK says "its time to
generate data for the next block" and the app does it right there and
then. obviously, some mileage may vary :)
