buffer for M5

so what size buffers are you using for M5.
does 512 cut it or do you need to go lower for
latency free performance? how much lower?
Is it even a consideration for a G4 dual 800?
Thanks

IMO, 512 buffer is workable, but the latency is definitely apparent. If you can tolerate a little "mushiness," then it might work for you
I tend to do my MIDI work at 256, then bump up to 1024 once all's tracked to audio to mix. I'm on a dual 2 G5, FWIW.

256 should work, as long as I don't have too many things going.
Guess some more RAM will help.
decisions, decisions...

If you run at 256, how many VI instances can you get away with? I'm on a dual 2.5 G5. For the longest time I was using live MIDI input at 1024, and now I feel stupid for doing it that way for so long. I bumped down to 512, and everything is still very smooth. I guess I should try 256, boy do I hate latency.

This is a hard question to answer since different VIs have different CPU and RAM requirements.
As you know, the big reason to use a lower buffer setting like 256 is to minimize latency when playing.
On my set-up (G5 dual 2), 256 gives me good response. But it can tax the CPU if my composition is orchestrated with many, many heavy VIs. Still, I almost never have to bounce my VI tracks to audio until I've MIDI-ed all of the parts. So, I get a enough VI headroom out of my set-up.

As of right now I'm only using Battery 2 and Machfive as my VI's, and usually only one instance of each. Performance is great for me as well right now, my audio performance monitor is only in the 10% range of CPU resources being used. I would imagine I have some headroom to work with. I'll do some experimenting.
Thanks

Sounds like all's cool. Certainly, one instance of MachFive and Battery shouldn't be too much to deal with.
