Dave, I expect they ARE very different with the XK1C being much more authentic.
Would the VR-09 hamper my enjoyment of learning and playing organ tunes? That is my objective. I really don't need the syntheprizes inside the VR. OK I do like pitch-bending.
I played a lot of Rascals on that first Hammond-Suzuki "X" model with a "synth" keyboard, back when I (apparently) had money.
Before that I used a Yamaha DX-21 synth for organ. Egad!
Before that I played Mom's Wurlitzer organ in the living room - also with diving board keys.
Blissfuly ignorant and necessarily frugal. I would love a real Hammond clone, but for 60% more and twice what I paid for my piano, what will I be missing?
