If you're a synth freak, and have been pining for a solution which would enable you to have a 1u rack mounted mixer and audio interface, one that is capable enough to operate coherently without the presence necessarily of a running host computer or DAW, this product may well blow your mind. For the past five years, it's been a never ending buying and trying and selling routine going through quite a few stand-alone solutions ala Mackie Onyx and Presonus StudioLive, hybridizing via a traditional and robust mixer Yamaha MGP16X paired up with any one of the many audio interfaces out there. Chasing after a configuration that "works" has consumed countless hours and more than enough $$. For geeks like us, MOTU "gets it". Their products deliver. Far better than any solution I've ever attempted.
