I think having more than the standard 4 encoder wheels on a console whould speed up programing, especially with channel-laden devices like Catalyst. This is originally why I had eariler asked about MIDI and hog3. I wanted to map out fixture parameters to a Behringer BCR2000 and have up to 32 simultaneous encoders of control. This is also great for shuttered fixtures like VL1k. Sometimes it is much more intuitive to grab a real knob that is always in the same place doing the same thing.
