Which leads to the following question I've been asking myself for some time:
the ALSA sequencer API seems to allow *timestamped* events - you put such
an event in a queue and it will appear at the other end at the right moment.
If this is true, and if ALSA has an high precision timer available to
implement it, why should apps like MusE bother to do the fine timing
