MuseScore2.1 AppImage with Trinity r14.

Hi, I am trying to get my go to program for writing music, MuseScore to work with the Trinity desktop. I am aware that Trinity uses aRts for sound and I would prefer to keep the default. When starting MuseScore with aRts, the MIDI score playback is greyed out. I have been told that apulse is a possible alternative to PulseAudio, but I have yet to find anyone that has gotten MuseScore to work with aRts or apulse. The alternative is of course to install PulseAudio, but I am trying to keep Trinity as vanilla as possible, to avoid problems down the line. Does anyone on the list use MuseScore with aRts or apulse, and how did you get it to work? I am new to Trinity as I never used KDE 3.5 when it was available, but I am loving it now. I have Trinity installed on top of a Devuan (no systemd) Jessie minimal cli install. Thanks. Brian
