If it's as great as the T4 was great over the T3 (not a whole lot, LOL), I'm not sure it's worth losing sleep over. I tend to like to skip at least one generation, if not two, between arrangers. Gives them a chance to add a WHOLE lot of new things when you upgrade..!

No, of course the T5 will be a great unit. The T4 is a great unit! Will the T5 be enough of a GREATER unit to warrant the upgrade..? We'll see.

And if it were a lemon by Roland, I'd call it as such, musicforyourday. I have no brand loyalty. I own Roland's, Korg's, Yamaha's, Kurzweil's, used to own most every brand out there. And when they sucked, I said so..! I've been quite critical of the BK-9's screen issue, but now there are iPad workarounds, I'm pretty happy. If it were otherwise, trust me, you wouldn't see ME 'defending' it!
