I spent a couple hours listening and comparing "Hammond" organ sounds.
Genos, SD90, and Hammond model. These are illustrated in the posted video..

I listened to all the organs in Genos including optional packs.

I would not want to play the Genos as a naked organ..

Compared to the Hammond (best), and the SD90 (very good).. the Genos is very bright, it doesn't have the Hammond warmth.. it is too digital.

I found it more suited to sounding like a transistor Lowery or Thomas.
Organ players would know what I am talking about.
I also think Yamaha makes it too hard to get to drawbars.

I am wondering if the SX900 or Tyros5 are as weak in "Hammond" sounds..

Still no hands on to verify my opinion, but usually YouTube is pretty true with sounds.

Acoustic Piano, and the new Sax sound good..

I got to hook up with Donny and try hands on.. If he doesn't leave me alone in the sandbox again
