Hello from Durham, UK.
I've recently come across frescobaldi, lilypond and rosegarden and have installed them and started to explore. I've looked at Musescore but find the textinput aspect of Lilypond quite attractive and I feel it may suit me better than a GUI. I'm running Debian Bookworm.
I came across these boards while digging around for information for my setup. I can see rosegarden playing midi files, but there's no sound. Exploration shows that audacity also recognises and silently plays midi files. I don't have any problems playing music in other apps.
I'm currently at "no midi sound in debian bookworm" stage and trying to make some sense of what I'm finding.
I've just done a fresh install of Debian Bookworm and of the apps (or Appimages) and taking stock. I can play MIDI with timidity and fluidsynth AND HEAR THEM, but rosegarden I can see the instruments but no sound.
I'm going to do a bit more reading and look at the rosegarden mailing list, but in the meantime if anyone has a working rosegarden Debian Bookworm setup I'd be very interested in any tips.
Dougie
