New to the forum... I have a DMX Operator and was disappointed when customer service told me that the board could not be controlled via MIDI. Since the board HAS a MIDI input that just didn't seem right. Indeed, I'm successfully using a Behringer FCB1010 foot controller to externally trigger the board. The FCB1010 is a pain to program, but once you're done it works great. The FCB1010 has 10 banks of 10 patches, so I match the first 8 patches/bank with the 8 patches/bank on the Operator. I use the 9th & 10th patch/bank to trigger a blackout and a chase (having some trouble with the chase since it won't "chase" unless it's in "auto" mode). Hope that info is useful to someone.
