Whenever I record on a software instrument track, and play no notes, Logic creates a 1 bar empty region during the count-in. There is no sysex in there either, no midi at all in the region.
When using "drop" then an empty region is created from the point where the track is dropped into record.
Problem has only recently started, after trashing preferences.
On Logic 10.4.8, in Mojave, Mac Pro Trashcan 8 core.
