Personally, I think Casio are going to HAVE to copy Yamaha's Mega Voice technology, multipads AND SA technology and do it just as well as Yamaha to stand any chance of competing against them. Let's face it, even REALLY good sounding arrangers like the Roland's are generally very poorly received because they don't have these 'must have' features, despite having a long list of stuff the Yamaha's don't...

It's going to take more than just the kidnapping of a few Yamaha reps from the US to get the job done, and let us not get TOO excited... Product lag will make anyone who has JUST joined not have any impact for probably three to five years from now. They don't just sling these things together, or develop mature technologies like SA2 overnight.

From what I gather, it's the guys at Yamaha UK that have a LOT more influence on how the Tyros and PSR's get voiced and feature priorities, so purloining a few Yamaha guys from the US might not have as big an influence as you might hope. This ain't the Tyros R&D team here. It's marketing guys. Not that Casio couldn't do with some help to get them over the bad old days memories, but let's wait and see...

I think it will take FAR longer than you are hoping for.
