M4 : 1 year later, Still Amazing

The m4 is definitely worth its price.

Build quality is really good, Encoders feel smooth, buttons clicky and responsive.

The connections aren't wiggly and usb c is perfect.

The outputs are solid too especially have 1/4" jacks for both 1&2 and 3&4 outputs.

Inputs are crisp and low latency, good enough for me to play guitar.

The screens are helpful and the headphone jack drives my headphones very well.

The asio is simple to use as well as the loopback feature.

To use this for music production/podcasts is a no brainer this fits the bill across the board.

My only issue is that loopback, line in (3&4) monitoring, volume knob and headphones all only work through 1&2 output channels. If you use your computer for a multitude of tasks, I imagine gaming or DJing would be under it- I like to route my game audio through my speakers and have voice chat through my headphones and would furthermore like to use my headphone output for cueing when Djing. However you can't have the headphones use 3&4 output channels. I have instead been using 3&4 outputs as my main audio from my computer. This basically means I can't use the volume knob which becomes another unneeded issue to make sure all my software is turned down as, again, I can't control the incoming volume on the m4. It would be good is motu allows users to pick which outputs channels are for monitoring and headphones.

All in all this device is still one of the audio interfaces out there at the moment in its price range and would recommend to anyone.
