Is it just guys don't see the lack of quality in the so called professional arrangers by Yamaha..The last Yamaha[maybe only one]arranger was the 9000 Pro..It suffered in sales..why, because of all the plastic models made available with in the same company..Any way you want to look at it the TYROS2 on down are not made as well as the "Pro" models of the other manufacturers.

Ketron has the SD1..Korg the PAxPro, and Roland the G70..BTW I don't think it is a coincidence they are all 76 keys.[hint]..
