I don’t own one. but I do see the value of it. basically the way I see it is: if I wanted to actually mix and sum a track through this, I would. I would never do that through a Mackie 1202, for example. nor would I use its mic pre’s to track through. it’s difficult to get a decent quality mixer that’s less than 16 channels. most of us here don’t need a ton of channels or a rack full of compressors and such. but we’d like to try our hand at mixing and summing out of the box. this gives us what we need for that, with quality sound, at a pretty reasonable price for what you’re getting. and I absolutely wouldn’t mind tracking through it.
maybe that’s delusional to you, and that’s fine. nothing wrong with recording direct through your sound card and mixing in the box (what I do now). some feel this adds more.
