Agree.
From what I have read, there seems to be a least three ways to use a mixer:
1) One is for live/on-the-fly performances, where , as per your example, one could have multiple sources to mix/experment with, and then later back to the DAW to record into a final product as a stereo mix. I think for this mode, the 2 channel USB is fine.
ie SOURCES -> MIXER (two tracks) -> DAW -> FINAL ( eg mp3)
2) Another is as per (1) but to record the inputs as individiaul multiple tracks, for the purpose of mixing or removing some tracks in the DAW, before makiing a final product as a stereo mix. For this mode, one would need the multiple tracks USB outputs (or something like a basic mixer +
a TASCAM US-1641).
ie SOURCES -> MIXER (many tracks) -> DAW -> FINAL ( eg mp3)
3) Another is as per (2), but to feed back some of those tracks into the mixer, for a final mix using the mixer, and then back to the DAW to record the final product as a stereo mix.
ie SOURCES- > MIXER (many tracks) ->DAW -> MIXER -> FINAL ( eg mp3)
For me. I would likely start with (1), and later experiment with the others....which still leads me back to the TASCAM M164UF as the better choice.
As for Behringer, almost every google search points to a red flag caution. Good assessment
here. Even on this forum (which I value for advice and guiidance) seems aligned with what I read elsewhere, The informal Behringer
poll results gives me great cause for concern. Excluding those who vote dont-own or dont-care, of 368 remaining votes (a pretty good sample size), 35% love the Behringer product line, but a full 65% thought is was so-so, sucked, or would never buy again. I would take chances on a $30 accessory, but not on something I am putting $500 down on.
