I’m trying to teach the Surface reader application the meaning of various buttons and faders and the like in order to make a protocol definition so as to be able to use the Digi003 with the Surface reader, however i have a problem: I manage to teach the surface reader about 7 or 8 buttons and then a message similar to this occurrs for every new button, fader or knob i try to learn: "Pre3 Highpass Filter already uses that MIDI message. Do you want to overwrite it” this is in a dialog with a yes and a no button. What do i do now? Is there anyone else on this list who happens to have a Digi003 surface and who can chime in and help make this accessible to the Surface reader or should i maybe switch and try my Project mix instead? /Krister
