Hi
I feel my seq24 is a bit untight. I thought it was due to my clock
resolution was set to 250 hz (std ubuntu setting) so I grabbed a new
kernel, patched it with
http://people.redhat.com/mingo/realtime-preempt/ and switched clock
resolution to 1000 hz.
However the (slight) untightness is still there, so it must be
something else. What should I look for?
I run xubuntu 6.06 and the problem is observed when seq24 drives
hydrogen. It's worse when theres activity on the machine.
seq24's midi thread runs at a too low prio even in realtime mode.
change line 1007 of perform.cc to:
schp->sched_priority = 80;
and line 1565, too
That helps on my box..
Ah and of course run seq24 with --priority
Also make sure your irq/jack priority setup is ok. Read for example,
