Midi Keyboard Suddenly not being recognized

I’m a new user to Dorico (and loving it!) - but every session, at some point, Dorico Note Entry stops recognizing my Midi keyboards. I need to quit and re-launch Dorico to solve the problem. (I can still play the keyboard and hear the sound played by Dorico)

I saw discussions here suggesting that this is a system MIDI issue, but I have 2 MIDI keyboards connected to my computer, and they both are still recognized by other MIDI software (and by Dorico, except for Note Entry), so it’s not a connection issue.

Any advice will be greatly appreciated!

Can you give us more information? What OS? How are the MIDI devices connected?

Do you still see the little green light in the bottom right corner of Dorico’s window when you play on the keyboards, or is there an exclamation mark there?

You may get more help if you supply a Diagnostic Report (from the Help menu) after it has happened.

Thanks!
Working on Mac OS 12.4, Midi keyboards are connected through USB.
There’s a green dot on the bottom right corner (regardless if I play or not), and Dorico does play the correct sounds when I do, but does not receive note entry until I re-launch.

Also - I’m realizing this happens when I use a MIDI trigger on another software (“Transcribe!”) - after I use a playback MIDI trigger, Dorico (sometimes, not always) stops responding to MIDI note entry

Attached Diagnistics report,

Many thanks!

I sometimes have a similar problem (MIDI keyboard keypresses not recognised). My solution, switch keyboard off (little switch at the back) and on right away. The key presses work again.

Thanks, but that doesn’t work

Then may be your Transcribe software is grabbing the midi data?
macOS has a utility, called Audio-Midi Setup. If you launch it and switch to the window with the midi devices, you might get some information from it, not sure though…

No, Dorico still recognizes the MIDI signals, but they don’t work for note entry

Let’s see if @Ulf can find the problem.

If you press the keys on the computer keyboard: will they produce note input?

Yes, they work perfectly

Sorry, but from the log files I also get no hint, at least not from the audio engine side.
@roeeli , you say that the green light in the right bottom corner of the Dorico window is always on, is that correct? If that’s the case then one of the MIDI devices must be constantly sending some MIDI data, like MIDI status or controllers. I wonder if Dorico might get flooded and can’t handle data any more at some stage.
In the Dorico Preferences dialog on the Play tab are some Recording options if you scroll down a bit. One of them is called Filter out MIDI Controllers. If you tick that one, does it get any better.
The fact that the VSTInstruments still react to the MIDI events makes me assume that Dorico itself has a problem with MIDI handling here. Maybe @PaulWalmsley could say something in this respect.

Thanks, seems like you’re right - I’ve got Stream Deck sending MIDI data to trigger Keyboard Maestro macros, and another dedicated MIDI controller attached - it seems like filtering MIDI controllers is doing the job. Thanks a lot!

Excellent, I’m so glad to hear that.
