Hi Andrea and Scott,
I'm suprised too ! You absolutely did the right thing Andrea and you will love the SD1 for sure.
The noisy DSP is still there and the drawbars sound 'not OK' compared to the Native Instruments B4

(The best ever since the real tonewheels

)
The latest upgrade to OS3 solved some problems (e.g. style delays) and the SY roothless chord recognition is implemented AND can be set to ON or OFF (great feature)
I expect Ketron will implement some of the user-wishes in future releases.
My SD1 performs fantastic and never let me down.
Roel
