My name is Don and I'm a keyboard addict.

First Yamaha arranger was PS 50.
Then:
PS 70
PS 6100
PSR 6300
PSR S500, 550
PSR 8000 - first Yamaha with vocal processor/harmonizer
PSR S650
PSR 740, first Yamaha with 4 style variations
PSR 9000
PSR S900
PSR S950
PSR S970
Tyros 1
Tyros 2
PSR SX900 - FINALLY touch screen and joystick..
Genos
Along the way there were also four Technics, five Rolands, six Ketrons and six Korgs! Also four arranger modules, Yamaha QY something, Ketron Midjay, Roland BK7m and Ketron SD40.
I currently only have three arrangers, Roland EA7, Korg PA4X and Yamaha Genos.
Korg PA4X is my favorite of all time!
Genos is for sale. As wonderful as it is, I don't care for the 76 keys. Too wide for my setups.
