I guess visualdmx would give midi-feedback to the panel for fader-positions and other information.
I see i made a little typo there. I meant: VisualDMX
could give midi-information back to the panel. Actually, now i'm thinking about it.. The only occasion feedback from visualdmx would be handy is when a cue stops others. First i thought, it might be usefull if you change parameters in visualDMX self, so the faders respond to program input (but mostly those are live adjustments and do not directly apply to the complete cue).
This way it wouldn't be more than a funny gadget.
Maybe the panel itself remembers fader-settings while switching between pages. But thats all speculation till someone used the device.
If i'll get the chance i'll try one out (or order it sometime, it's pretty inexpensive).
