For reliable operation MusE needs "realtime priviledges".
Kernel >= 2.6.12
- load the set_rtlimits utility from:
http://www.physics.adelaide.edu.au/~jwoithe
- compile & install
- create an audio group (if you dont have one already):
groupadd audio
- add yourself to the audio group
- create an entry in "/etc/set_rtlimits.conf":
@audio /home/ws/projects/muse/muse/muse/muse -1 90
- start MusE with
set_rtlimits -r 60 /usr/local/bin/muse
========================================================
Low Latency
========================================================
Start JACK with a realtime priority of 60 (option -P60).
This should be higher than all (Realtime) system processes
if you run a realtime kernel (with Ingo Molnars realtime
patches). The JACK default priority is 10 which is too low.
MusE must be started with a higher priority than jack.
This allows the MusE midi thread to interrupt all
audio threads. This is important to get a midi timing
which is of higher resolution than the audio segment
time. The default priority of 70 for MusE should do.
