This might be due to these applications not setting their midi and clock
threads to a higher prio than i.e. jackd's prio.

If i.e. the muse midi thread runs at a prio lower than the jack audio
thread it will be interrupted by the latter once each process cycle.

There also might be other causes, but it would be cool to check this
first. Maybe check back with the muse devs for a definite answer [i
don't use muse, nor rosegarden, so i can't tell]..
