Hello all. Does anyone happen to have a copy of the manual for this unit with 2.0 firmware? I've searched high and low and can only seem to find the 3.1. I'm really most interested in the Program Matrix and Parameter Matrix, mostly because my "4" and "9" buttons aren't working (bummer)...so I'd like to see what I"m missing by not being able to use them. Other than that, the unit sounds great, but I'm not sure if trying to get it repaired is worth the while or if I should just make due without the use of those buttons. And I suppose, lastly, are there any recommendations for repair persons? I've found a few names so far but figured I'd ask again since you never know who else may be out there. Thanks.
