Dave:

Also you can assign the pads to many fuctions besides sounds, Fx, etc.. and still give you the EC5 Footswitches...

Other new things are that like in the PA1X ( not available in PA80), the pads has 3 modes, so, you can do more things too.
Also pads synch to tempo with the syles if you have made a secuence groove in the pads.
It does take some time to customize it, just like you would do with ANY other comparable models in other brands.
I hope you enjoy it as much as I do.
