I am new to the synth and midi and sequencing world -- so take this with a grain of salt. I own and XP80 and Triton. I agree with EVERYTHING said about the Triton's poor piano sounds. I am into authentic sounds -- and I would have to say that Roland is better. It's a shame that a $2100 keyboard has inferior piano sounds -- but EXPANSION boards apparently will address this. And the person who made the point about OS upgrades --- bravo! That is a good point.

The reality is that neither is the perfect machine -- and each has great features that the other doesn't. IT's ALWAYS win-lose! If sampling and "user friendliness" are super important to you -- the Triton is great. But Roland -- i will stand firm on this -- simply have better sounds and samples. But AGAIN -- expansions and upgrades will close that gap soon!
