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
themselves ?
Yes, my thoughts exactly. You don't even have to use the ALSA sequencer
API, you can use the ALSA timer API directly. You get multiple timer
sources (system, RTC, sound card). It should also be more portable.
For example if your sound card's timer is supported by your ALSA driver
like emu10k1 and ymfpci then I think you can use this timer to give
better sync with the hardware.
ALSA devs, is this correct?
