Found at the back of my bookshelf, it's yours for the price of postage from the UK!

It's the complete guide to the Wavestation A/D, very detailed, I just don't speak Italian or own a Wavestation. The MIDI/SYSEX implementation and the wave sequence file structure are in English.

I figured if anyone is going to want it, they're probably on this forum...
