The following video shows under what circumstances the multi-midi editor considerably slows down.
When you see the cross next to the mouse cursor, the action to move the note has been triggered.
- The slowdown happens when moving notes left/right that are in an item without the green arrow activated.
- Moving notes works as expected when using the mouse as well as with key commands if the green arrow of the corresponding item is activated
Here is the demo project from the video above:
