Has anyone tried Rosegarden and other linux audio apps on the newest
Raspberry PI?
I have not. However, it would be an interesting test case.
On my laptop (an ancient 1st gen i3) I see about 1.7% CPU being used
by RG if I launch JACK after RG is up. If I launch RG after JACK is up,
I see about 15% CPU for RG plus about 4.3% CPU for JACK. So, if you
don't use the audio subsystem (audio tracks) in RG, you can likely
reduce the CPU usage considerably. That might make it a lot easier to
use RG on a Pi.
Let us know how it goes if you decide to try this route. We might
need to add a "disable audio" to the preferences to allow for easier
performance tuning. We also might need to do some further performance
tuning in the code. I'm always up for that.
Ted.
