Your post caught my eye as I used to own an Estey electric organ. It was a weird hybrid of accordion and organ. The right hand played a 3 octave organ keyboard but the left hand was unusual. Instead of organ type keys, it had accordion chord and bass buttons!

I just saw one of those about 2 months ago. I had never seen one before and the owner gave a quick demo. Very interesting to say the least!
