Have you tried doing a Google Bill, There IS an MS 40 owners forum and they're pretty good. Used them a couple of times for my own MS40. Damned if I can remember the url though. Have you heard of the V3 desktop ? It's been designed for accordions, and is utterly incredible. Wife bought me one for a present last month and I've played with it every night. It's very small & neat but pretty costly. Cool point is that you can make up some backing tracks using biab and save as MP3 which you can then play via sd card through the V3
