Hi Jeremy!
When do you get xruns caused by LMMS? Do you get them all the time while you
play a song or only when you load a project or change/add an instrument?
I rarely get xruns when I play a song with LMMS (with jack and a rt kernel) on
my machine excepted if I use many zynaddsubfx instruments and many effects
(more than my system can handle). I do get xruns occasionally when I change an
instrument or when I load a project. I guess these actions overload the CPU for
some msec, but I don't think I would need to execute these actions while
recording... LMMS is quite CPU intensive and I think it's normal because it has
to play and generate many sounds (+ effects) at the same time. But I usually
don't get xruns during playback with a rt kernel...
