Funny, I used to haul around organs that weighed several hundred pounds. Now I'm wincing at the thought of a plus 30-pound arranger! Last organ I had, and I mean LAST, was FS500. What a beast. Then add Leslie, dollies, etc. No wonder lots of us have bad backs in our old age.
To me, the problem with Tyros is not so much the weight, but the shape and design. It seems really bulky and hard to handle. I suppose the bulk of them are setting in living rooms or music rooms so it doesn't matter.
I wish Yamaha would incorporate those incredible lead voices in a design that would be really portable. I think people would pay the price! How about a Tyros module that weighs about 12 pounds?
They would sell out the first two days!
