Thanks for that.. But I dont think it solves my entire problem as I still
have questionable timing when driving the builtin soundfont synth on my
soundcard.. And by the way, hydrogen is by _far_ the best drumloop
sequencer in linux.. I am quite happy to export completed loops as wavs
to use in Muse as a workaround for the time being.
