Thanks for the info Os. I've a licensed version running now, it works great in combination with Mainstage but only if you sync it to the Mainstage clock. I switched of the preference "midi output" and switched on both "Host" and "Master". > Possibly you can do something cunning with automation of > Mainstage itself, but I've never used it myself so can't advise. That's a good suggestion. I know you can do something with Apple Scripts in Mainstage, have to figure that out ;) --- Sjaak http://www.livelooping.be/ http://www.overgaauw.be/ http://www.myspace.com/sjaakovergaauw
