What is important however is that the latency is constant, jitter
is quite obvious.


Makes sense, how often is jitter in that regards a problem and if it is a decent amount of time, what might be done to help with that problem?

MIDI latency is typically
1ms or so, and that's generally not a issue.

Yea a ms or less definitely wouldn't be a problem for what I am thinking of. I tend to think slightly higher might not be a problem either, but I was worried it might get over, say 3 mS which I think might cause a problem. This is overall between GUI and communication.

Getting lower than that in
a UI + OSC connection is no problem.

That is good to know and exactly answers my question I think, thanks.

In any case, it's not a good idea to run GUI theads at high priority as
they often have to do actions which require a significant ammount of
wall-clock time.

Again thanks for the information.

If your thinking of using a UDPish protocol, please use OSC.

Was definitely considering it. I suppose my question there might be, while I don't have intentions for it currently, I don't want to rule out the possibility of the FE running on a separate machine, and I would be worried about packet loss with UDP over a network or possibly wireless connection (Not looking for wireless for show conditions, more for say in a theater show when I might be setting cue levels by running a FE on my PDA). But yes OSC is definitely looking like a good possibility. Of course I haven't looked to see if there is an OSC lib for my PDA much less most PDAs;)
