When you're in the PRV you can drag a note up or down and the note will trigger the sound related to the VSTi which is a good thing because you can hear which note you're moving to. However I decided to add keyboard shortcuts/bindings to move the notes up or down. The problem with this is that it no longer triggers the notes which is not very useful. So be nice if this could be added in a future version.
