I’ve wished for a note move function for ages, but afaik it is not present in VariAudio (anyone?).
A pseudo-workaround is to go into the other mode (by hitting TAB when you’re in segment mode), then effectively move the musical note by grabbing/dragging the left and right edges in turn.
That is actually the time stretch function, but when you move the left and right borders by the correct amounts, the time stretch returns to zero.
In the end, I usually try to move notes in the project editor, not VariAudio, but I’d be interested in hearing how others do it.
