[SOLVED] Need help setting up MuseScore

[kwatson512]

I'm trying to transition from Windows 7 Pro/Sibelius to Linux Mint 14/MuseScore for my music composition needs. I've installed MuseScore 1.2, but can't get sound to work for listening to MIDI and other note inputs or for playback.

Here are the error messages I see when starting MuseScore from a terminal:

Code: Select all

$ musescore

Here is a screenshot of my (default) MuseScore I/O Preferences.

I use a Yamaha Clavinova to input notes, connected via USB to my computer. This works perfectly with Sibelius under Windows, but I don't know how to set it up in Mint. That and having playback work are absolute requirements. Any tips would be very welcome!

Marking this as solved. I installed qjackctl and rebooted. All is well.
