Midi output sets velocity to 1 for all notes

[Flying-Roger]

Issue type

General playback bug

Bug description

For any score, the playback on a MIDI device produces very weak sounds. Reason: the velocity is set to 1 (on a 0-127 range) for all notes. Note: a beat sound is also heard (metronome?), with the same velocity = 1.

Steps to reproduce

1. Create a score with a few notes
2. Assign the output device in the preferences.
3. Capture the output MIDI port and check the velocity in the notes messages or listen to the keyboard sound.

Possibly a good one to tackle together with a range of other midi-related issues. (@cbjeukendrup FYI)

I have same problem in all Ver.4 series. This is a sample MIDI output. I used the Web App "Send And Receive" to capture the MIDI output routed by virtual MIDI driver "loopMIDI". I showed note on message "90 pp vv" in yellow. "vv" is velocity value. You can see that all values are 01.

I have just monitored an empy score midi out, and found that Musescore sends strange midi messages on every measure, just when crossing the bar line. See attached image.

Tested again today with Musescore Studio 4.3.1 to confirm that the problem is still there. I see that the issue is still open here on github, so probably not tackled yet.
