Thanks! That worked.

I did, however, notice that I had forgotten to have any LADSPA plugins
installed when I compiled. Do I have to recompile rosegarden again now
that I have some plugins available or is there a way to set them up in
Settings?

I've also noticed that my kernel timing is off for this new build. From
the rosegarden FAQ: http://www.rosegardenmusic.com/resources/faq/#toc31

If you see this message in an error dialog when Rosegarden starts up,
then you are probably using a Linux kernel that doesn't offer
sufficiently high-resolution system timers for MIDI use.

Rosegarden uses ALSA sequencer queue scheduling (inside the Linux
kernel) for its MIDI output. The sequencer queue can use a variety of
timing sources, of which the default is the kernel system timer. The
kernel system timer was 1000Hz in Linux 2.6 kernels up to 2.6.12, but as
of 2.6.13 it's now 250Hz in mainline kernels. This is not good enough
for good MIDI timing...

This is news to me! Before I go recompiling my kernel again does anyone
have any good idea why this was changed since 2.6.12? In other words,
(once I figure out how to) will a post-2.6.12 kernel recompiled to use
1000Hz break anything else?

Thanks,
