nice to hear that you solved this. I'll have to check that MBLink and perhaps MBNet stuff for my purposes too soon. Can MBNET access and change the actual values of the encoders in the chosen layer? Or can it only handle a parameter "inside the sidapp", meaning I cant access parameters "of the control surface"? (sry for that bad english ;D) I havent read into that stuff very deeply yet, but it were nice to know if you could give me a good starting point for that. greetz
