Korg micro-Arranger: .75" Wide x 3.1875" Long
Yamaha Tyros 4: .875" Wide x 5.5" Long
the main key size difference between Tyros 4 and the micro-Arranger
is their respective key 'length'. Tyros 4: 5.5" ; microArranger: 3.1875".
On the other hand, the microArranger's key 'width' is only .125" narrower than Tyros 4.

To my mind, the key width , although important (and in this case minimal!) is not as important as the length from the leading edge of the white key to the black key.....I have measured the distance of this on my PSR9000 as being 1.8" which is comfortable to me rather than any shorter... any shorter IMHO would really make it a toy!
but of course that would possibly belie the powerful range of the Micro.
any comments anyone?
