Moving score around with mouse causes audio "hiccup"

• Mar 19, 2024 - 22:48

I have been dealing with this problem for a while now and I'm honesty getting quite sick of it. It started maybe a year after I upgraded to Musescore 4. Every time I move my score around with my mouse two things happen.
1. My mouse gets extremely stuttery (this only happens specifically when I'm in Musescore)
2. Any other audio that happens to be playing (i.e. browser) blips in and out until I let go of the mouse button.

update It also happens randomly when I'm entering notes, or lyrics and when it does whatever keystroke or click I happen to be in in that split second of the "hiccup", it repeats that actions like a few dozen times within a microsecond, picture typing the letter M and having, like, 20 Ms appear in the lyrics all the sudden or 20 C7 chords or whatever else, quite annoying.

I have tried uninstalling and reinstalling several times. I have no idea which system settings to check. I have restarted my computer countless times trying to resolve it and also both of these things in different combinations, so I know it's a specifically Musescore problem and since reinstalling it didn't work, I know it's not my system. I have a feeling it's something to do with the absolutely horrendous playback engine updates in version 4 and I kind of regret ever being excited about VST or advanced mixing options at all because nothing like this ever happened with Musescore 3. And now that all my files are in version 4 I can't go back, which is quite frustrating.

If any developer sees this please do something about it!

If you are on Windows, there is a "How To" in the support section that will tell you what setting to check.

  1. Can't say I've ever had this happen. Though your gif is pretty small for me to be sure.
  2. You have other audio playing while using MuseScore? Most notation programs are pretty jealous and want complete control of your sound card. It has nothing to do with the playback engine. The above How To will tell you how to turn off Exclusive mode. And make other adjustments to your system.

You can absolutely go back to MU3. And don't bother with re-installs. The uninstall doesn't get rid of everything. The only way to do that would be to search for and delete everything related to MU4. And like every other program on the planet, many files are hidden.
