Hi Ted!
My "unfavorable" settings in the recording parameter menu (all midi input 
devices, all channels, midi through auto routing) are causing a cpu load of 
104% according to "top" - didn't know that is possible :-)
Choosing only one midi input device, one fixed midi channel and midi auto 
routing to off solves this problem.
Thank you and cheers, Michael

Try using the "top" command (at the command line) to make sure 
Rosegarden is to blame.  It will show you the processes that are using 
the most CPU.

Hi there!
Does anybody experience this behaviour too:
Since the latest commitments (code version 1589x - 15904) the cpu load rises 
strongly (in my case 45-60% and more) when Rosegarden is idle and in QJackCtl a 
lot of xruns are generated. After loading a song into Rosegarden and starting 
to play this song the CPU load falls again (maybe 5%) and no more xruns are 
generated.
 
I am using Debian 10 with a RT-kernel. Ardour and other Softwares behave 
properly, so I think it is Rosegarden. I didn't see this behaviour before the 
latest ALSA-Midi-Port commitments where added (code version 1588x).
 
Greetings Michael
