Well maybe better late than never.. I looked into those a couple years back, and I decided against it. There seemed to be a lot of uncertainty as far as the firmware and compatibility. Basically from what I gathered if it could be somewhat flaky. There were accounts of people who loved it with no issue, and others where it was the opposite. I just ended up leaning towards the avid artist series, which uses the Eucon protocol, and is compatible with samplitude, and most of the major daws. That and the higher resolution of the faders due to the Ethernet connection vs usb midi/Mackie MCU.
We had 42 channels of MCU while I was at the studio daily, and about 24 of them worked well.
Since my info on the icon is rather old by now, I’m curious your experience with it. Congratulations (or sorry to hear it) on taking the plunge!!
