From a T3 owner and former PA2x owner. Go with the PA2x for live use. you will benefit from the dual sequencer, XLR mike input,Songlist,76 keys, better harmonizer (albeit not today's TC Helicon by a long margin) Go with an external harmonizer. They are far better then any internal one I have heard or played around with especially for live use where feedback is important and immediate.

Which sounds more impressive? thats subjective. I would say the Tyros. Thats what I ended up with and am satisfied with for the most part. Bur for live use I would have kept the Korg as it's features cover that arena better.

Effects....I did not get that deep into the Korg. But I am satisfied with the T3's ability to assign EFX and the quality of them.

Keep in mind though the Tyros has a far larger and more divers library of native styles to select from. That was the straw that broke the PAXs back in my world. Lack of available useful style choices and support.

Sufficiently confused? Good we all were in the beginning before we found what works best for our needs,and what compromises we could live with in that regard
