So teh main reason I suggested teh ability to connect to the rig is we have 1 RGB par in a store room that he can connect into directly... everything else is in the rig. RGB pars and some relatively cheap moving heads. Due to the unique way the school decided to fund the drama department, we have no means of getting the lights down from the rig until they do their yearly show, when they rent a cherry picker! So for now, the only way to control more than 1 light is to link it to the desk. Perhaps you're right that it makes a bit more sense now for the student to adapt it for moving heads as touch screen is really intuitive, especially for kids who play on their phones all day long! They took a long time to get used to positioning the lights with two linear sliders so some sort of joystick would be good! But again, the moving heads are in the rig! thanks everyone for your thoughts, it probably would have been better advice to look at movers rather than rig integration but it was the end of a long day, clearly my brain was mis-firing! I'll chat to him again tomorrow, it might be that he is keen to design a merger as well! If not I'll suggest a cheap moving head. With an HTP merger, as long as the desk values were set to 0, could you control a moving head through HTP? Until this thread I didn't know there was a difference! As a photographer I work visually so usually help out with design rather than the tech side!
