I need to play mainly metal and rock type music, so basically I need the basic string/choir pads, organs/pianos, some bells and orchestra stuff etc.
I know this is a korg forum so opinions are probably going to be biased, but maybe you can help me a bit anyway, I already own the X50 and one plus of it, is that it cuts through in live situation, though its not as good in studio. The sound is a bit dated too, and the FX section is very dated for reverbs and stuff.
I havent had a chance to test either of these boards, due to living in the middle of nowhere...

Anyway some pros and cons:
Korg M3,
-sampler (I probably dont use though)
-Much bigger ROM, like 5x
-Probably cuts through like korg
-Pads are probably better
-I already have similar X50
Kurzweil PC3x
-Organ simulator
-Better engine and FX
-Orchestra is said to be a winner
-VA inside
-Very small ROM/ old samples, weak drums.
- Cons of both boards seem to be a weak Piano, but I cant justify a Yamaha Motif cause it has no good pads or strings.
OK I hope you can help me a bit with this decision.
BTW does the M3 have the Dynorchestra 2 preset from X50?
