Keyboard input randomly stops working

• May 1, 2022 - 06:06

OS: macOS 10.16, Arch.: x86_64, MuseScore version (64-bit): 3.6.2.548020600, revision: 3224f34

When the problem occurs, I can still enter notes with the cursor, but not with the keyboard. The problem seems to occur at random.

Keyboard entry on new scores stops working, too. Closing the score and re-opening it doesn't help. Quitting MuseScore and re-launching it makes it work right again, until the same problem re-occurs. I've been noticing this for the past year or more, and it is not getting better. It happens about once every half hour of use, I'd estimate. I can't figure out how to reproduce it.

You probably already know about this, but I thought you'd want to know.

Okay, the problem just occurred. I haven't used MuseScore much lately.

I can fix it by quitting and restarting MuseScore, but I won't do that until I get a reply, in case I can help with troubleshooting.

To answer your question, the right side of the status bar at the bottom of the screen says, "Normal mode." If I click on the "note input" button at the upper left of the screen, then the right side of the status bar at the bottom of the screen says "steptime note input mode."

Musescore was working normally until I inserted a new key signature part way through a score that previously had a different key signature. I'm not sure that this is always a trigger for the problem, but it might be.

Any other way I can help troubleshoot before quitting and restarting, thereby making the problem go away?

Strange... It started working again. Don't know why. I named the score, which was new, and saved it. Toggled the "pan score" and "metronome" buttons on and off. I'm not sure that's the reason it started working again. I've had this problem several times, and I'm pretty sure it doesn't happen because I'm making a dumb mistake. Don't know what to think now. I'll keep you posted.

Okay, it happened again, i.e., MuseScore once again became unresponsive to keyboard input. My current theory is that it happens when I view the palette and drag something - a time signature, this time - from the palette to the score. The palette was closed when it stopped working but dragging a time signature from the palette and then closing the palette was the last thing I did before MuseScore stopped responding to the keyboard. By trial and error, I got MuseScore working again by viewing the palette again and then closing it again.

I'll keep you posted.

This has been reported often enough that there is no doubt it's a real problem - pretty much exclusively on macOS - but unfortunately still so rare that no one has succeeded in finding a way to reproduce it. Knowing you are in Normal mode does help confirm it's a real problem, in case there was any doubt, as it eliminates the possibility you were in Edit mode. That which would be the one known "user error" that would disable most keyboard commands.

I tried doing a few things with the palette, like I did before. Couldn't reproduce the problem. Reproducing it probably requires a specific set of circumstances or sequence of events. I think it's related to dragging something from the palette to the score, for what it's worth.

Okay, I kinda sorta reproduced it. I opened the palette, dragged a couple of time signatures into the score, closed the palette. (This doesn't always lock out the keyboard, but seems to cause it pretty often.) The keyboard stopped responding. The cursor keys didn't work nor did the number keys or note keys. Saving didn't help, toggling other things didn't help. Opening the palette and closing it again got things back to working normally.

Edit: Just reproduced it again, this time with a key signature from the palette. Opening and closing other windows didn't un-freeze the keyboard, but opening and closing the Master Palette did un-freeze it, even though I triggered the freeze with the Palette (not master). I hope that will help you track it down.

Hmm...
So, with the keyboard (shortcut fn+Shift+F9) being locked, you were only able to access the Master Palette using the mouse and the menu: View → Master Palette to un-freeze. Yes?

It's hard to say if it's related. Most of the time, keyboard entry works for me. I think I sometimes trigger the problem by dragging something from the palette to the score, like a time signature or key signature. When I correct the problem by opening the palette or master palette, then closing again, it works fine again, for awhille.
