Description

Issue type

UX/Interaction bug (incorrect behaviour)

Description with steps to reproduce

When using a MIDI keyboard, entering chords and entering single notes show different behaviour with respect to capturing key velocity information.

From within MuseScore, select File→New and click "Done" to accept the defaults.
Key 'M to select "Input by duration".
On an attached MIDI keyboard, firmly play and hold two keys, then key 7 before releasing them. This fills a single bar with a semibreve chord.
Gently play and hold the same two keys, then key 7 before releasing them. This fills the second bar with the same chord.
In the property inspector, select playback and note the velocities.

Expected behaviour: the velocities should be "unspecified/follows dynamics".
Actual behaviour: the velocities differ between the two bars and, in each bar, between the two notes entered.

If single notes are entered rather than intervals or chords, the velocity data are discarded and the score shows velocities of 64. This is better but, in both cases, I believe the velocities should be "unspecified/follows dynamics".
