It does its primary job as an interface just fine. No complaints about the sound. Build quality is good. The software is nice, really straight forward.
Extra things I like:
- it has a small USB hub built in
- it can be set to sleep mode in which the lights are off by long pressing on arturia logo button
- it can be powered by external power supply which is provided
- works without a computer, the software remebers last settings, so sometimes I can play my instrument without turning the computer on
