Sounds like you have a MIDI loop on your system. If you have trouble finding out where that is happening in your system configuration, please ask for help on the official Support forum.

Thanks for the feedback. I will check out that possibility and report back if I find out anything useful. I would still like to keep this issue open since the problem does not occur with the same system/setup when I use 4.3. It seems like something the developers would like to investigate since I doubt I will be the only person with the problem.

Thanks again for the help. I just checked my configuration files (asound.conf and .asoundrc) and both were empty. In addition, I checked sound/midi connections that were in existence using Qjackctl. No loop backs showed up. However, when I disconnected MuseScore 4.4 from my output (using Qjackctl), the repeating notes stopped, and then started again when I reconnected the link.

So, it does look like there is some kind of loop back, but it does not appear to come from my system set-up or at least not anything that is obvious.

[MarcSabatella]

Why are you using Qjackctl with MuseScore in the first place? If you're not using MIDI input or output, you shouldn't have that connected. But if you are using MIDI input and/or output, you definitely need to configure your system in such a way you don't get MuseScore's MIDI output being routed back to its input.

[mrmayfield]

I am not using MIDI input/output. I just used Qjackctl to check connections. I don't normally have it running and did not have it running when I first discovered the issue.

The latest nightly master (29 Aug. 2024) seems to have fixed the issue. As such, I will close this issue unless it pops back up again. Thanks to Marc for responding with suggestions.

Just in case: the fact that it's fixed in the nightly build may also mean that it's a MuseScore settings issue. Nightly builds namely don't read/write configuration from/to the same folder as release builds, so that they can be used independently. If the issue indeed comes back in the next release, you can fix it by resetting to factory settings (Reset preferences, in the Preferences dialog), or taking a look at Preferences > Audio/MIDI.
