The Genos has the edge. T5 is no slouch...but new features on Genos make it the winner.
Of course...JMHO.

T5 may not be a slouch but I would never go back to a T5. Once I got a Pa4x, the T5 just didn't do it for me. On the other hand the Genos is a real step up from T5. As great as both boards are I give a slight edge to the Pa4x for live performances. Much has to do with the VH/mic controls on the panel.

Ditto I agree Steve the KORG Pa4x/Pa1000 navigation is well thought out for the LIVE performer and is critical.

So many details on the 4x, like writing the input on the back edge so you can plug things in without turning the kb around. That's just one; there are so many.
But Genos does sound might fine. I tried one and like my Korg better, but I know not everyone would.

As minor as that feature may sound it is HUGE when setting up.

Both are 'King Of The Hill' arranger keyboards, and I'm really looking forward to the day I have got a TOTAL Korg into the rack, whether it is stacked below or above Genos.
