Too bad Hammond never did adapt the overhanging and slightly tilted down upper. I had it on my Thomas and Yamaha's and it was great...especially when bridging upper to lower...they were REAL close.

Donny, If you get that combo you will be back in the 60's with a organ and a SIDEMAN, remember those??? That was before styles!

I would not want to have to use the SD90 itself, but have a MIDI controller with lots of sliders, switches knobs etc on the controller....then, look at all the setup work...
As they say in the NE...forget about it!

I don't think the Hammond would make a good controller kbd at all.
