  • This applies only to multi-staff/multi-instrument scores, and when NOT in input mode ("N")
  • Mouse-clicking on an element of a measure (e.g., note, rest, cliff, measure bar) and playing a note on MIDI keyboard erroneously produces the instrument sound of the first (top) staff.

Steps To Reproduce This Condition:

  1. Connect a MIDI keyboard, start MuseScore
  2. Create a score, 2 instruments: piano (top), cello (bottom); add some notes to each.
  3. Exit Input Mode.
  4. Play MIDI keyboard to hear back Piano audio
  5. Click on a single element on a Cello measure (a note, 4/4, cliff) -- and press a MIDI keyboard key. MuseScore erroneously plays back Piano audio
  6. Workaround: Range-select notes/rest in Cello staff -- now MuseScore correctly plays back Cello audio [per Mark Sabatella].

This is not a problem in Input Mode ("N") -- which plays back the correct active instrument sound when MIDI keyboard is played.

This issue is critical for those composing directly on MuseScore and use the MuseScore instrument audio to "practice" or "audition" a few measures of musical ideas before transcribing it via the INPUT MODE "N".

This is an old issue - going back several versions of MuseScore. This is reproducible on Windows 10/home/64 and Ubuntu 20.04/64 AppImage.

Severity S4 - Minor S3 - Major
Workaround Yes No

I would like to second that. I just got started with Musescore (which is an absolutely great tool), nevertheless I do not think there is a workaround for the problem.

Would be glad to hear about a workaround. Otherwise, as this is really distracting, I'd like to suggest raising the severity of this issue.

(For completeness, this is my scenario: When I start recording e.g. the bass line of a jazz chart using real-time note insertion from a midi keyboard, then the first staff sound - in my case vocals or flute - is played instead of the base sound. It doesn't help to click the staff first (which ensures the correct sound is played while not recording), as the sound changes to the first staff once recording starts.)

Thanks a lot for the tool! Much appreciated.

Frequency Once Many

I have the same issue.
I often have 5 to 10 instruments in one score. When playing a note or chord on my MIDI keyboard, 9 out of 10 times it's the wrong (first) instrument.
Reason/flow:
. I listen to the score I have so far
. I correct a note or two by selecting just the note, and with keyboard arrows move them up/down. I hear the correct note of the instrument. Nice!
. I then often think: would this other note sound better? And I press a note on my midi keyboard. Alas, the played note gets the sound of the first instrument WHILE my selected note remains selected. Confusing!
. when selecting the whole bar, then I hear my MIDI notes with the correct instrument - but with this bar selected, I cannot update notes individually.

So it's kind of impossible/very impractical to switch note selection/bar selection, to just hear notes coming from the same instrument WHILE seeing a note being the selected note of that instrument.
