The latest in MOTU's award-winning UltraLite series, the UltraLite-mk4 is a USB audio interface with 40 simultaneous I/O channels (18 in, 22 out). It also delivers exceptional sound quality, new ultra-low latency drivers and expanded DSP for studio-grade mobile audio recording.

Similar to the Ultralite AVB... albeit without the AVB part.

 
I am looking at this. I don't need the AVB. I have been following the thread chronicling the driver issues some have been experiencing with the AVB units. I am not sure if the drivers are the same.

USB and AVB has different drivers. The only difference i can se from MK3 is both inst/mick is in front, and you have dedicated PAD buttons.

The converters are newer than mkIII units... and have slightly lower noise-floor.

Ahh. You shouldn't.. Now i have to buy this...
Oh wait. I'm broke. Anyone wants to buy a good, working, used UltraLite MK3 to the same prise as a new MK4?

The AVB driver issues will be temporary. The older version driver is rock solid and works great. This new problem is only happening on computer reboots (which won't affect a lot of people).
I'm sure the MOTU guys will fix this. They seem to know what they're doing, and seem to respond when there are problems.

I wouldn't talk myself out of one of their interfaces because of this.

I just bought a demo mk3 from Sweetwater, oh, two weeks ago, and then the mk4's came out:(
 
I haven't spent much time in the studio, but I was up and running in short order and I thought the clarity, the crispness of the mk3 as compared to my Roland Quad Capture was significant.  Idk, are the converters really that much better or am I fooling myself?

I wonder if this one has the same issues the previous MOTU units have with USB 3.0 Ports... My Surface Pro only has that connectivity to offer... I bought the PreSonus Studio 192 Mobile due to those having noted issues with 3.0 Ports, but I'm wondering now about this unit.
