I am not in a rush by any means as my beloved S-950 is doing an Amazing job on stage for the last 18 months!!!
At least you and your 'beloved' KB have lasted longer than another 'beloved' couple I am aware of ... many years ago our band was going to play a wedding for this couple ... the drummer and I (co-'leaders' of the band) met with the couple a few times to make all the arrangements ... the groom to be kept calling his bride to be his "beloved" - "what ever my "beloved" wants, I want her to have, nothing is too good for my "beloved" ... well the 'beloved' couple didn't last 6 months after the wedding ... perhaps HE wasn't too good for his 'beloved' either ...
Tony...it's just a term I use for the moment as I have learned from my mentor Uncle dave..."Everything I have is for Sale"....
including my "Beloved S-950.......

If I had to change again at this point I would certainly go back to another KORG Pa3x 61 or Pa900.
Ps: and YES 18 months with one Kb is a record I'm proud of at the moment.
