I use Logic and have the latest version.
I have VEP Pro 5 latest version running on PC
When I use Native Instruments products the tempo sync does not work.
As soon as Logic starts to play tempo synced instrumenys stop.
The latest instance of this is with Kontakts Retro Machines and FM8 that use the Arpeggiator.
Something is very wrong with the implementation of the tempo sync with these instruments.
Even is you disable host sync in FM8 the arpeggiator stops as soon as Logic plays.
