Sorry I guess I didn't make myself very clear
there. I don't mean that I
wan't to make an audio ap and would do the audio stuff myself, I'd
definitely use Jack for that. I'm making a step sequencer to drive midi gear
and csound synths. So the timing I'm concerned about is the engine of the
sequencer outputing midi notes and csound events via pipes.
ah, yes, a very different question indeed. well, there are several
apps to look at:
TSE: a library for doing MIDI sequencing
muse+rosegarden: full fledged MIDI+audio sequencers
softwerk: a MIDI "analog" pattern sequencer
and probably quite a few more from the "MIDI" section of the linux
sound+midi pages (linuxsound.org).
in general, you can't get excellent timing under linux without kernel
patches, but you can do well enough that almost no human will notice.
as far as using pipes go, they are pretty damn quick under linux.
about porting it to a ucontroller - unless the ucontroller runs within
a POSIX-like environment, i suspect that writing portable code for
this will be rather hard.
