Just wondering. Without an RT kernel here, my 2

simple audio needs pretty well at 64msec latency. At least, it's never
bothered my playing along with computer-generated audio.
I don't do any heavy-duty audio work here. Once I tried Jackrack, put
one effect in it (that worked) or one amplifer (that worked) but trying
to use both didn't. But I don't know if that had so much to do with
latency or lack of RT kernel as with a smallish amount of memory and an
underpowered processor driving the whole thing. Now that I''ve upgraded
the memory on both laptops, perhaps it would work? On musicbox, with
512MB, using a single good quality (larger) soundfont was enough to
cause problems. With 768MB in it, it works without problems.
I see people on the list running much lower latencies than 64msec, and
seemingly trying to get even lower ...
So, just wondering.
If you are doing anything with live audio such as effect processing or
synthesis from MIDI input, you will probably want sub-20ms latency.
If you are just recording then higher latency may be prefered to reduce
CPU load and the risk of xruns.
But I don't want xruns when playing live synthesis from MIDI input, either!
