I have lots of MIDI type stuff I want to do (on Mint 13 Xfce), so I installed Timidity and a soundfont. Now I can play any MIDI file on the command line by doing this: "timidity examplefile.mid" and it plays the file perfectly, with all instruments playing. However, when I use a program (banshee, movie player, or others) to play a MIDI file, it plays the file but I only hear a few of the instruments playing.
I suspect (although I don't know for sure) that the programs are using Qsynth (which came with Mint 13) rather than Timidity. How can I disable Qsynth and enable Timidity as a default for these programs?
