I still think this argument is way over emphasized. And it got me curious. I still own the once famous Roland E70 which I retain for its stupendous acoustic piano sound and did some comparisons, just for the demanding ones among you.
Turns out the keys on the Korg are about 5 mm longer than on the Roland and that........here it comes!!!........the keys on the Roland are less than ONE millimeter wider than the ones on the Korg PA-50. Satisfied ?
