I'm a new member- , excited to share thoughts, ideas, tips with other owners of this remarkable instrument.
I have a PC3K8- around two decades back (!) I first got bitten by the Kurzweil bug with the K2500XS, sound was terrific, but those damned weights kept breaking out of their cases-
Now many years after, after using the Nord (Stage 2) for some years (and never being really satisfied)- I got a used K2600 (by now fully loaded)... and that got me back into the fold.
