Don’t know if you will find anything on the market that does everything the MTK does. I have the bigger brother, the 22 MTK. I have had it for about year now. I wanted it for the same reason you do( a multitrack USB interface) and I could not find another mixer that did the same things as the 22 MTK anywhere in it’s price point. Perhaps something has come up in the last year since I purchased but I am very happy with my mixer(on board FX’s are “fine”, but doesn’t matter as I stack as many VST effects as I want per channel). I also really love the EQ’s on sound craft mixers.
Someone asked me on the “Your setup” thread about my mixer and this is what I told them :
The build quality is pretty good. I don’t think I would take it on the road or anything but everything feels pretty good I don’t foresee it kicking the bucket anytime soon. Nothing is too plasticy feeling. Fader have a good amount of travel and I love the EQ’s. Nothing is too wobbly. Overall the mixer feels heavy and solid, especially for the price you can get them at! Feel as good to me as a Mackie, A&H, or Behringer in the same price point(but without as many features!)
Hope that helps and happy mixer hunting!
