q-light

Hi, How do I patch/assign a traditional 6ch dimmer? Do I treat it as a fixture with 6 dmx channels? I then want to use them via the submasters - then if I were using 24 channels of conventional lights I could for example save a plot of dimmer ch 1,2,7,8,21 to submaster 1 - that's the theory - how do I set the levels and then save to the sub? thanks
