Reply to VCI-100 Overlays ... whats the difference?

Just got myself a FW Kit to upgrade my standard VCI-100 controller.

Im looking at the overlays in the DJTT shop. Whats the difference between v3 and v4 overlays?


I mainly like to play House, techno and Drum n Bass, pretty much straight forward mixing with 2 decks.

Would like access to some nice effects too.


Im a bit of a beginner in the controller world (coming from 1210's and CDJs).

Thanks
