AJ, much respect to you for how you've represented your company and supported it's products. I've never owned a KETRON product but I do recognize it as a quality product (albeit with suspect manufacturer support). Here's my problem:
Why is it that after spending premium dollars for a supposedly TOTL instrument that one must immediately spend a ton more money to realize it's full potential? To be fair, your company is not the only one guilty of this (Roland, and it's 'Roland Cloud' is just as bad, maybe worse). IMO, Yamaha is least guilty of this. I gotta' admit, I hate this 'Barbie Doll' approach to marketing. Just so there's no misunderstanding, I'm talking about ENHANCEMENT packages, not CORRECTIVE software (bug fixes).
JMO tho', other's may feel differently.
