As for the hardware part, got a couple Pioneer SDJ-08 monitors, Beyerdynamic DT770 Pro Headphones, AKG Perception 220 condenser microphone, Roland R-05 Wave/MP3 Recorder, M-Audio Keystation 88es, KORG Monotron and Monotron Delay, M-Audio Fast Track Ultra, and a custom made chiliGREEN laptop which pretty much works as a desktop replacement. It's a monster!more
ALL this being said, the unit works well & these are just critiques on optimisation and what I personally would tweak & my opinions of it.
Signal lights work well, unlike my scarlet interface which doesnt indicate signal at reasonably low levels has midi ports & thus saves extra usb ports on your laptop/pc having 6 jack outs and inputs on the back is a big pro for the unit allowing it to be used with external fx processors. AND having two headphone jacks works well for colab with artists eliminating the need for a headphone amp most of the time :)
annoying that only two out of four channels work without external power, but oh well - usb power is usb power... Can be frustrating to use as a system soundcard.. (my laptops sound drivers spaz a bit if i try to get youtube or etc to play through it) - works fine with DAWs Individual phantom power controls / divided group controls would be a nice option Volume knobs are a bit touchy Also shouldnt be too hard to convert the last two xlr ports into composite xlr/jack like the first two.. so could be designed a bit better.
