Dave, I loved a lot about the SD7, but the length of it made me do too many compromises in my setup. I would reconsider it under certain circumstances for sure, but certainly not now with all that is going on.
Put the time and effort into it and you will love it.
I'll be happy to share my registrations with you if you like.
A good thing about Ketron registrations is that they contain ALL the information saved, even if that information is not present elsewhere on the board or drives.
