I'm not seeing the right program names for my MIDI device (or any at all)
Rosegarden has an internal Studio to map your MIDI Program Change information into meaningful instrument labels. You need to set this up do this mapping in the MIDI device manager (Studio→Manage MIDI Devices→Banks or Import). Once you've made changes in your current Rosegarden file you can save it as a default studio (replacing your autoload.rg file) so that all your subsequent sessions in Rosegarden utilise your specialised Studio settings.
The commands would be as root,
you may need admin password to do this...su to root, [enter password]
rm -rf /usr/share/rosegarden/autoload/autoload.rg
I hope this helps.
