Hey, trying to use my MIDI keyboard assigned to massive but cant seem to do it. I own a EST Keycontrol 25 which has 4 rotary knobs and I am trying to assign them to the Massive attributes page so that I can use one of the macro controls for my filters etc. When I select the drop-down menu the only I can seem to use from there is the modulation wheel and I have no idea how to set up one of the knobs to control macro 1, all their doing right now is controlling volume or something. Any help?
