Crash on playback + automatic note input

• May 22, 2025 - 05:50

Since the addition of the "input by duration" feature, starting the playback automatically switches on the "input by note name" mode and starts adding notes until Muse Score hangs/crashes. This is most easily reproducable if anything on the score is selected when you start the playback, but sometimes happens if nothing is selected.

macOS 12.7, Arch.: x86_64,
MuseScore Studio version (64-bit): 4.5.2-251141402,
revision: ac9d3bc

To reproduce:

  1. Turn on "input by note name" and add notes to the score.
  2. Turn off "input by note name". Select the note you want the playback to start from.
  3. Start the playback either by pressing the space key or the Play button on the toolbar.

=> "Input by note name" turns on automatically, and notes start getting automatically added to the stave
and are played until Muse Score hangs or crashes.

I am unable to replicate this on my computer. I used both your score and two different scores that I created (one some time ago, the other just now). I tried exactly what you described. Then tried each input mode with both Space and Play to start playback. In no case did I see anything like what you describe: All worked normally.

I've narrowed it down. This seems to happen only if MIDI input is enabled: MuseScore Studio > Preferences > Note input > MIDI devices > Enable MIDI input

The crash happens whether or not a MIDI device is plugged in. I've turned MIDI input off for now.
