I am working on my CS6X and also on a PLG 150-AN controller. I read someone was also doing a PLG 150-AN controller. Is that person still working on it? If yes, maybe I should focus on the CS6X only then. I encountered an interesting problem in the PLG 150-AN layout construction. I have a list of voices called Preset 1. I have a list of voices called Preset 2. And I have a list of Voices called user. When I select the Preset 1 list I would like to have a Knob K containing all the tick names. Now when I select the Preset 2 list I would like to have the same knob K have the tick names of Preset list 2. Is something like that possible? If not, is there a way I can disable a GUI component when pressing a certain button? For example, I have radio buttons Preset 1, Preset 2 and User. Next to that I have a knob for each Voice list. When I select one of the buttons, the other 2 knobs are disabled. Is that possible?
