does the maudio air have multi client drivers ? cos thats a lovely feature for me on win.


I don't know what you mean by "multi-client drivers" and only pay attention to Windows when I am paid (that ended 2020). I found the manual less than complete but here it is.
AIR 192|14 User Guide

There's only one downloadable driver and it's Windows

one statement of yours i found very surprising was the comment bout no blend control on motu m2.. but it's there on the m4. i assumed this was 'de rigeur' these days.


I know, right?. I was surprised by that omission. In fact, I'm still surprised that none of the Scarletts have it.

Although the M2 has better meters, the Mackie FxPro6v3 costs $10 less, has 4 more analog Ins, the monitor blend knob, built in hardware FX and a number of other features. It is now what I recommend when users need only 2 out over USB. For Mac users, no drivers needed for 4 In over USB unlike the M2 (Win drivers support 2 Out/4 In for both).
