I've 3 strings of 100 pixels working fine with three outputs of the P12 with Vixen 3. If I want a mega tree of six strings of 50 do I have to chop the strings in half and use six of my outputs? Surely Vixen and the Joshua can be configured for a logical layout. I've tried using the effects on the Joshua but it seems to block the instructions from Vixen (no lamps light for the output I configure). Has anybody else encountered this problem? Fixed I? I'm missing something simple. Surely? Richard I guess I can sole it all back up again.
