Right. MuseScore supports JACK MIDI, but not the ALSA sequencer. If you're using MuseScore and want to use its MIDI capabilities, you need to look into using the JACK audio server, and configure the server to use either the "raw" or "seq" JACK MIDI routing driver. You will also need to enable MuseScore's JACK MIDI capabilities in the I/O tab of the Preferences dialogue. Please see [1], for an explanation. I hope this solves the problem. If not, feel free to re-open this bug.
