MIDI Editor: The ability to preview note changes when moving them with the keyboard

When editing MIDI I like to move the selected note around with the directional keys. This is of course easy to set up in the action list. But when I do this, the note changes are not heard, even though 'Preview notes on add/edit' is switched on.

I'm not sure if one should characterize this as a bug, but one easy way of overcoming it would be to implement a 'Play selected note'-action that then could combined with e.g. 'move note up one semitone'.
