MOTU M2/M4 new audio interfaces

The no-compromise and entry-level audio interface MOTU M2/M4 – it’s something that should be impossible, but MOTU might have just cracked it.

I have literally been trying to pack suitcases for a long trip, staring at audio interfaces because I can’t find the one that does what I need. I’ve been equally stumped sometimes asking inevitable questions from friends about what they should buy.

MOTU has always made great audio interfaces. But many of them require drivers, which means your Linux-running laptop with Bitwig Studio or your iPad with those great new Eventide apps are both out of luck. Or they don’t fit a small budget.

So the MOTU M2/M4 (M2 / M4 )genuinely surprised me. They have the specs of a high-end box from MOTU or others, but they start at US$169.95 and at last they also work with every OS, all squeezed into a portable package.

Here’s what you might not expect From MOTU M2/M4:

High-end converters

2.5 ms latency with their drivers

A high-res color screen and built-in metering (unheard of at this price)

RCA outs? MIDI I/O? Sure!

But that’s not why I say they’re really no-compromise (though the high-end converters surely go there). MOTU did their own custom USB drivers for ultra low-latency performance on Mac and Windows but they also made this class-compliant – so it doesn’t need drivers on Linux or iOS or Android.

And then the pricing is stupidly nice.

So finally, one little box does everything – and if you get into the iPad or Android or Raspberry Pi, you don’t have to go buy another interface.

Yes, these are USB-C but that will also connect to your existing USB A connection.

Promising stuff – I’ll be interested to pick one to review (or pick up one to hopefully keep).
