When I picked mine up a few years ago, I had big dreams that I could use it as both an audio mixer and MIDI controller for my hardware. What I didn’t think about was the inability to change the MIDI assignments on the unit. So, the MIDI portion is great for controlling Traktor, Ableton, or other software with assignable MIDI. Not so great for controlling external hardware. I suppose a person could use software or something like Bome’s MIDI Translator, Raspberry Pi, etc to convert the cc’s, but I was never that motivated to make it work. Another thing to watch out for is support on newer operating systems. It’s no longer receiving updates for Mac (10.14 or 10.15 is the latest version, I think) and I’m not sure what’s happening on Windows.
The analog mixer, on the other hand, is great. I love Allen & Heath mixers. Top notch sound. Good EQs. Two multimode analog filters. Great build quality. Looks super cool.
Funnily was looking at one of these last week after it popped up locally of Facebook marketplace and I was thinking it would be great for my deluge and digitakt. Each midi side controlling each machine but hadn’t factored you can’t change midi cc numbers. Deluge has a midi learn but still would be great if it had an editor app on the a&h
