Twelve Years could be the charm.
One should be able to manipulate MIDI Events -inside- the Key Editor OR from the In-Place Editor.
Select the scissors anywhere -except- a note should DIVIDE the Event in two.
Likewise, if one is editing two Events inside the Editor it should be possible to ‘glue’ them together.
Oh… and while we’re at it, Repeat Events should -also- function inside the Editors.
And don’t get me started on how one should be able to manipulate tempi and time sigs inside the Editors.
