Ok well I worked out a workaround for anyone that needs help to do that : setup tap tempo on a midi button on my apc mini and midi map all clips in resolume to buttons on the apc button matrix then tap to tempo of any song played from iTunes (make sure all videos are preprogrammed to around 8 bar llength and set speed to any tempo that you pre tap out ) and also set autopilot for each video to what setting you like ( play next , play random ) then when your iTunes music plays you can jam videos to any tempo you tap out on the apc and using resync button and tap tempo button you can autopilot and live play your videos together to any tempo of any music thanks resolume hope this helps anyone that wants to do that kind of thing
