I'm not sure if this is the right place to send this. If there's a better place where I can get help, please tell me.
I made a rosegarden project and exported it to a MIDI file. When I play this file with Timidity it sounds wrong- too much sustain on every single note. The original file still sounds fine on Rosegarden though. I wanted to check whether the problem is in the exporting or in the playing (in Rosegarden or in Timidity) by importing the MIDI file to Rosegarden, but now when I open QJackCtl it stops immediately after I press "start", so I can't play anything with Rosegarden.
Another issue I had (when QJackCtl worked properly) was that Rosegarden constantly crashed every now and then.
Can anyone help me?
Here's the output from QJackCtl, in case it's relevant:

This is a good place to start at least.

Afraid I can't help with Timidity.
The original file still sounds fine on Rosegarden though.

It sounds like something else, probably pulseaudio, is using the soundcard (the output you posted also seems to show that). Can you try adding this to 'Execute script on startup' in the QJackCtl setup menu, options tab: pulseaudio -k
Another issue I had (when QJackCtl worked properly) was that Rosegarden constantly crashed every now and then.
What version of Fedora are you using? Also versions of Rosegarden, QJackCtl and Jack would be useful, you can get these at the command line: rpm -q jack-audio-connection-kit qjackctl rosegarden4
It might be that not being in realtime mode is causing crashes, see https://fedoraproject.org/wiki/JACK_Audio_Connection_Kit#Running_Jack_in_Rea... or it might just be a bug in your version of Rosegarden.
Here's the output from QJackCtl, in case it's relevant:
Yes, this bit shows it trying to get control of the sound card (hw0) and failing.

Sanity check, do you have only one sound device connected? In QJackCtl settings if you click the '>' button next to settings does it show different audio devices?

Are you using at the same soundfont in Rosegarden and Timidity?
There is soundfount ramping in timidity which you can configure. Default is none.
man timidity
