Don, maybe your solution is twofold..
Did you ever consider combining a Hammond SKX with a Ketron SD90?
Or a Roland VR-9 with a ketron sd90

Or the best Italy has to offer..
A GSI DMC-122 witg Gemini board and a Ketron SD90

Or the new fantom 6 with a ketron sd90


If you like the Ketron sound so much.. but dislike the keys and format of the SD7
Just add a keyboard you really like..

In the end, i am pretty sure the YC 61 or the 73 key nord stage 3 also would make great controllers, but keytouch might be a little heavy..
