Outstanding product. The M-Audio M-Track Duo USB Audio Interface is the best I've ever used.

Good sound, works well. Bit weak on the amplification (as many have said) for a passive bass, but still more than sufficient. It just means that I have it turned up further than I'd have to for my prior m-audio (the FW-410).

Worked perfectly on Debian 12 with no additional steps or tweaks required, including the monitor. To use it with Bitwig did require a bit of poking around to figure out what did what, but that's more on Bitwig, as it exposes a whole *pile* of input methods for this device.

Easy hook up easy to use!! It did everything they said it would do. Would recommend to a friend.

I LOVE IT!

I repeat, DO NOT BUY THIS!!! I bought this not even a year ago and I got the red lights of death today. No sound going in or coming out. You're better off spending your money elsewhere. Buy a Focusrite instead.

VERY ADEQUATE FOR ITS PRICE.
CON: NO UPDATES FOR WINDOWS 11.
WORKS WELL WITH MY OUTDATED CAKEWALK -SONAR SOFTWARE.

Had it for about 3 months and every day up until today it's worked fine! All of a sudden I'm hit with odd alien noises that would make Ed O'Brien jealous and red lights on the interface.

My first try at using a USB Audio Interface, and so far, so good. The box is what I expected from online reviews so I am not disappointed by the cheap feel of the unit. Features work as advertised. my only gripe is the AVID Pro Tool-First free software is no longer included in the bundle. AVID apparently weren't getting anything from this arrangement.

The substitute is Air Creative Collection, which need to be installed into a DAW (Free Garageband or Audacity).

Looks clean, simple, well built and works. Very very good for the price point, I do recommend to anyone that needs an audio interface to get this instead of something 2x the price such as the Focusrite; this does the exact same thing.

Fantastic sound no distorsion or cracks.Very happy.Thank you.

M-Track Due fits very well my voice and guitar projects. It is easy to control; I had no undesirable noise in my recordings. The price is reasonable. I recommend this interface to those who record podcasts and simple projects.

As the title states, DOWNLOAD THE DRIVERS FIRST. Don't plug it into your computer without having downloaded and installed the drivers from M-Audio's website. Once this is done, the plug and play part is fairly easy. I didn't bother with the software. I already have a sub for the standard Pro Tools. This is a huge upgrade from my M-Audio Fast Track that I got back in high school in the early/mid 2000's. I used the FastTrack to do quick arrangements for my band and the Duo will help me by adding a second channel to connect both my synths for even faster workflow. It's perfect for what I need and it arrived way quicker than I had anticipated.

Plenty of headroom, clean sound.

USB Drivers for Linux (jack) worked plug and play. Headphone amp is very weak. Have to have it at 10 to get similar level to the Focusrite Scarlet 2i2 volume at 5. I'm using it for some real time audio over the internet app and had to modify the software to add up to 12 dB of gain to make up for the weak headphone output.

I also note that the gain pots on the top are top heavy. The action from 8 to 10 is double that of the from 0-8. Not really sure. The pots mechanically feel fine, but the behavior just feels off. Like 0 is not close to zero.

The input selector for the inputs also does not seem to have nearly the impact as the one on the Scarlet.

I was really hoping for an economic alternative to the 2i2. Just a shame that some attention to these basic I/O details was lacking. Maybe a software update could fix this stuff?

Got mine yesterday. Drivers are a little iffy (lost sound to headphones a couple of times, had to unplug USB, or reinstall the drivers), and headphone amp isn't very powerful (compared to my Motu M2, which I LOVE). But otherwise seems like a pretty solid unit. I'm sure the driver issue will get resolved shortly, so not too concerned about that. Seemed to lose connectivity if I switched between my DAW and basic Windows functions (Windows media player would say it can't play a file, or it would say the Duo was connected and selected as primary sound device, but sound would come out of my laptop speakers???). I still think it's worth picking one up, and just deal with the quirks until the drivers improve. For $69, it's a good buy.
