Korg needs maybe only two things to REALLY give Yamaha a run for their money. First is more fills. Sorry, guys, I know that those of you used to it say you don't notice it, but every other arranger out there is using about six, plus break/fills or /mutes. Korg, you get two (plus a break/fill). That is flipping EIGHTIES...!

A four variation arranger needs more than two fills. Your four year old can do that math!

And then, any new Korg needs an EXTENSIVE set of brand new (not reworked) samples specifically for the DNC feature (Korg's SA clone). Without a ton of samples recorded specifically to leverage the legato and intervallic articulations, it's a TOTAL waste of space. Imagine a T2-4 with SA, but no samples for it... At least Yamaha 'get it'. The samples and the technology are ONE...

Those two things by themselves ought to push the PA3Xpro towards making it a VERY worthy competitor to the T4...

Just as long as they don't fill it up with useless bloody doo-wop samples!
