starting with version 2.2.105/3.0.25, changing the position of a MIDI event other than a note within the MIDI List Editor has become virtually impossible.
Any value used for a new position applied to a non-note event in the MIDI List Editor results in the event defaulting to a position of 0001.1.1.
The bug is highlighted in an extremely simple way:
1] A MIDI event other than a note is created at a position other than 0001.1.1 within a MIDI track
2] With the MIDI track selected, open the MIDI List Editor
3] Click on the position of the created event and change the current value to any value other than 0001.1.1
4] The new value for the event position in the MIDI List Editor will always be 0001.1.1
