Well, you lost me somewhere.
Even if you're using an analog to DMX controller, the end result is output on a specific channel, which will be interpretted by the DMX fixture(or dimmer) based on its DMX traits, but you knew that. Does't matter what the controller says it does, it may be something specific for what it was originally paired with.
Getting ADJ or other companies to reveal product information is a pain. No offense to anyone here, especially ADJ and Elation employees. From what I understand, there's lots of dirty pool in the business and everyone plays the same game. I may have some insider information on something but I ain't sharing, but it might result in a purchase of 8 of them, that's all I will say.
Back to your concept. If you could write something that could, for example, do an audio analysis to MIDI CC, there's a chance you could get what you want done. Similar things exist, such as guitar to MIDI converters, or even MIDI wind controllers(but those work more on note on/off as well as some CC data). Just having trouble with the mechanics of it, I've been busting my hump redoing my main computer and I've lost 48 hours(yes, that's 2 full days, and I work round the clock) that i can not afford to lose. I'm a bit wiped and edgy right now.
Once you have something that could do an analysis and dump out to MIDI, perhaps it could be used to trigger something like MyDMX on an RGB fixture, using pitch to determine color, and volume to determine brightness. All you'd need to do is assign the control information and you'd be done. And if you want to use multiple lights, you can double up on lights to channels, or controllers mapped to multiple channels.
The bottom line is that it's probable. Highly probable.
