I'd say that Yamaha's wind and brass SA2 voices still have the edge over Roland (let's be fair, they've been working on them for years!), but having played both, I definitely give the nod to Roland's SN guitars. For a first time out of the gate, they have absolutely NAILED those, and beaten Yamaha at making them playable and predictable.

I still get the odd twinge of jealousy when I hear a really well played SA2 sax solo... but OTOH, those are few and far between outside of edited sequences.

Look, every arranger out there nowadays has something going for it. If one of them held the edge in everything, well, nobody would buy anything else! My friend's PA3x is superb. My BK-9 is superb. A T4 is superb. We live in great times..!
