I was thinking "ms/note" (leaving "note" up to interpretation) and
"notes/bar" perhaps? It would be nice to come to an agreement to avoid

hi...
work and fst continued, and i was able to test some vsti synth.
i am totally flashed by arpegiators and i ask myself if we have one for
linux ?
does dssi provide for tempo sync stuff as required be arpegs and
adjusted delays ?
Other than the stuff you get from MIDI, no.
It would be a candidate for well-known ports in LADSPA I guess, tempo and
sync ports. There aren;t many tempo based effects in LADSPA or DSSI
though.

I've been working on the "beat-matchable" realtime sequencer concept for a
while. It's a tough problem. Writing something like Reason or Fruityloops
(which has such an arpeggiator) after you have a decent sequencer library
like alsa's, or rosegarden's shouldn't be too difficult.

A clock pulse, like MIDI clock, eg. 12 pulses per quarter note, and a sync
pulse every note or bar. They probably have to be audio rate.
That way you can use a clock divider (reset by the sync) to chop it down
to pretty much any required clock ratio.
You may also want a BPM numerical output for non-modular style plugins and
the like (when combined with the sync).
