Adding on to this issue: It appears this is happening on Mac as well.

I can confirm that Let Ring (MIDI sustain?) is not working with Muse Guitars on MacOS, MuseScore 4.2.1

Though this strikes me as a significant issue, but I don't see it assigned to the 4.3 or 4.4 project. Anyone know if it's there?

I don't see any "let ring" text as well, or are you referring to typing it manually? I would love for this to be added.

"Let ring" is currently in the lines palette.

Can confirm this is still not working for Muse Sounds in 4.3.2 - no sustain is added at all

Additionally, Let Ring does not sustain properly for MS Basic sounds - see issue #20992

This *still* is not working for Muse Sounds in 4.4.1, none of the sounds in "Muse Guitars Vol. 1" are sustained when paired with the "let ring" line (or even a pedal line).

Steps to reproduce are the same as OP

I'm popping this in 4.5, since the issue is really problematic for our guitar Muse Sounds and it's pretty silly that it still doesn't work.

Glad to see this progress!
