No, naturally, proprietary techniques from each keyboard type tend to lose a bit in translation, but that door swings both ways... there are things Korg and Roland and Ketron do that don't quite sound right on Tyros, either.

And no, of COURSE it is impossible to sound identical going from one arranger to another... But, especially for more legacy styles (before some of the proprietary stuff became commonplace in styles) you should be able to get close.

I see this product as sort of an 'instant EMC converter' in some ways, but it has the potential to go quite a bit further. For instance, there's no reason why it can't add a Chord Sequencer (may have already, I think Dan was working on that) so if your own arranger doesn't have that feature, now it does! Same goes for the Dynamic Arranger feature from Roland (you looked into this, Dan?), where the velocity you are playing on the keyboard adds or subtracts a bit of velocity from the Style Parts, and makes them follow YOUR dynamics. It's an amazing feature, currently Roland only, I think...

Out of the box, I think it is still a bit raw (I think there's considerable room for improvement in the translation tables) but you can edit all the styles played by it, so if there are better sounds and kits, you can tell it to use them.

My only regret is that it isn't an iPad or Mac app yet, but who knows? An iPad version would be incredible!
