<div dir="ltr">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.<br><br>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. <br>
<br>Another issue I had (when QJackCtl worked properly) was that Rosegarden constantly crashed every now and then. <br><br>Can anyone help me?<br><br>Here's the output from QJackCtl, in case it's relevant:<br><blockquote>
