Mo... Look, we seem to be getting too confrontational about these things (trivial things, too in the big picture). Yes, you have every right to ask for any darn thing you want, me too! Perhaps calling Roland moronic for not making an arranger with YOUR particular needs might be a bit inflammatory, but hey, it's your right! I get called out often enough for pointing out some moronic things I think about other's arrangers, too....

Maybe I'd better start posting in capitals when I say something that agrees with the original poster, because I can't tell you the number of times I have posted that I would like a lighter arranger, too, and had that fact utterly ignored by repliers...! (Seeing red, rather than reading black and white, I figure!). But, unfortunately, no-one DOES make a lighter 76 with the features and key-bed I want, so it's not like I have a choice (at least, not without more compromises than I am comfortable with), and I am certainly as fed up as you of being called a moron for sticking with my choice!

But, if you look at it, pretty much ALL arranger manufacturers make the product lines pretty linear. The middle of the line Yamaha does not have all the features of the TOTL, despite many who would be happy with that! Ditto just about every other manufacturer... They appear to have enough problems selling their existing lines (compared to workstations, where for some reason, weight isn't considered as primary a problem) without adding a whole lot more to the picture.

As far as the 'heavier is better' thing, it appears from your post (and my experience with heavier arrangers) that maybe there is a bounce 'gap' in the middle. Heavy keyboards not bouncing as much as 30 lb.-ers is just a fact of physics (takes more force to move all that mass, as long as your stand is stable)...

Ultra-light keyboards may not bounce as much as 30 lb.-ers, but so far we only have one example for that conjecture[, so we'll just have to see what comes in on this thread in the way of additional information. But a WS550 stand weighs more than the difference between a G70 and an E60, so if you want a light 76 and NO bounce, it may prove difficult to get.

I just get the sneaky feeling some 88 note keyboard player is reading this and going 'Storm in a teacup!"....
