Hi all,
I'm glad I don't play well enough for the small differance in key size to bother me.
In fact I did not notice the key size at all untill your post. I play a PSR 2100 stacked over a Roland VK7 and a Yamaha SY85 on my right hand side. I have no problem with key size at all. That may be from years of playing guitar and mandolin, each having a different scale neck and differant tunings. At 65 I don't think i'll let it bother me now. Just how I see it.
Have a good all, Smokey
