Interesting thread. I have a PadKontrol and a couple of older Roland devices; a Fantom XR and XV-5080 which all have 32-bit editor/librarian apps. They all worked fine on Win XP, but under Win7 X64, none of them will communicate with their respective devices whether Sonar has been running or not. However, Sonar works with them with no issues.
The Korg tech stated that you can't run the padKontrol software concurrently with Sonar 64 bit, due to the 32 bit/64 bit disparity. I'm finding this to be true. Admittedly, it limits the usefulness of the software--I can't make changes in the software, hit pads on the padKontrol, and hear them in Superior Drummer simultaneously. When Sonar isn't running, the ed/lib and padKontrol do communicate.
I'm hoping for a workaround and will be creating another post to try and get some answers.
