I took the K-mix back. It's got far too many things about it that are quirky and do not make much sense. I spent two days emailing tech support back and forth and while they were as helpful as they could be, they could not solve the problem. So, good luck Keith Mcmillen, I hope you guys improve your audio interfaces. there's a lot of great ideas in there. I'd probably ditch the DSP mixer portion all together and just have an audio interface/midi controller. And work as hard as I could to get latency down. I'd also have Thunderbolt 3 and USB-C ports. Good luck with the company, sorry it was too much work to get working properly and in the end after 5 days of trouble shooting, I said that's it, RME babyface Pro for me.
