  • 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.
