Weird Tuning on Ubuntu Bionic via Crouton

• Oct 12, 2019 - 16:25

Hello all,

Attached please see a score and .mp3 exported from it. The piano is tuned as expected, the distortion guitar and plucked bass are wacko. I'm using the default MuseScore_General.sf3 soundfont. I'm not sure where the issue is because of all the nonstandardness of my setup, but I'm hoping someone here has a clue.

Background:
I run musescore on my primary Windows desktop as well as an Asus C201 Chromebook using crouton. The fully supported path on the latter is still limited to Ubuntu 16.04 (xenial) and therefore musescore 2.x. Once I upgraded to musescore 3.x on Windows, this setup was much less usable because of the mismatch in file formats. So yesterday I upgraded my Chromebook/crouton/musescore combo to run musescore 3.2.3 on Ubuntu 18.04 (bionic). That seemed the only path to get musescore 3.x on this box.

Musescore seems to be running fine, and opens scores I created on Windows easily. But when I started to play back a score that had these three instruments on it, I heard the wacky tuning. There are so many things that might be causing this, I'm hoping some of the developers and power users here might help me focus my efforts to fix it.

Catalog of known deviations from the norm:
1) Crouton + bionic is not fully supported and before installation warns that "there may be issues."
2) To install musescore, I needed to use the ppa:mscore-ubuntu/mscore3-stable repository rather than the main one. Something's off in the build there?
3) I'm using the default pulseaudio. Note that pulseaudio worked fine for me on xenial with musescore 2.x.

Where should I start to troubleshoot this?

FWIW, it should have worked to stay with Ubuntu 16.04 and use the AppImage version of MuseScore. Since we (the MuseScore development team) produce the AppImage files ourselves, they are in a sense more "fully supported" than whatever the distrution maintaininers happen to put in their own repositories. according to my (limited) understanding.

Anyhow, first thing I'd suggest is to try the AppImage with your current version of Linux. I'd also suggest trying whatever other audio drivers are available. Next I would have suggest skipping crouton for this and trying the AppImage via Crostini, but I gather than might not be an optin for that model. Seems like there are other Linux options specifically for that? But downgrading to 16.04 and using the AppImage there might be wiser. Not sure. I'm no Linux expert, but I have setup MuseScore on a Chromebook crouton before (long before MuseScore 3) so I am at least somewhat familiar with the sorts of issues once can expect. Back when I was doing this, I thought I recall using ALSA, and also needing something called CRAS?
