List of Working/Non Working Class Compliant USB Interfaces

"Class compliant" may mean that it works with iPads and Macs without drivers. AFAIK there is no reference implementation or tester which audio interface _or_ host manufacturers could use to verify how class compliant their implementation is. If it works, it works. If it doesn't, it doesn't. You have now tested one MPC + interface combination and reported that it belongs to the category of currently non-working class compliant devices.

I don’t know if that is necessarily true. There are different errors with different interface issues for example, I tried to use the SKAA and received a specific error. My guess was that it would not work because there was an output but no input Akai verified that that is what that error indicated. Unfortunately now with this error, they are telling me to do a hardware reset and reinstall the firmware.

Native Instruments Komplete Audio 6 MK2 Audio Interface - works nicely with MPC One 2.14.0

Considering its power draw, I took the precaution of plugging it through a powered USB hub.

Roland Aira MX-1: works nicely as a USB audio interface with MPC One 2.14.0 - don't forget to set the MX-1's sampling rate to the MPC's native 44.1 kHz !

... But I don't use it as a USB audio interface, because I keep its "PC" USB connector to plug an actual PC for recording the master out and enjoy a fully digital audio path.

MPC sends to the MX-1 from the Komplete Audio 6's SPDIF out coax to the MX-1's "Digital" in - a perfect use of that. Well, almost perfect, because it requires setting the MX-1's sampling rate to the MPC's native 44.1 kHz - a pity since the whole Aira range is capable of 96 kHz... But good enough for me: at least it isn't analog !

MX-1's master out 2x balanced TRS go to Komplete Audio 6's input - and Komplete Audio 6's output 2x balanced TRS go to the studio monitors... Weird detour that lets the MPC sample from the MX-1. To reduce latency to the monitors, I might add an ART TPatch passive 8-channel patch bay to duplicate the MX-1's out to the monitors and to the audio interface, saving the roundtrip through the MPC... But it works for now.

For introspective studio work, I find the MPC alone best - but for screwing around with live stuff, the MX-1 is a very fun toy... And yes, that means TB-3 and TR-8 - but the live setup is about hands-on controls, so the MPC relinquishes some of its normal roles in that mode.

Yes exactly, I use it for that purpose. But you need the audio interface of course also.
As I wrote, I am using the iConnect Audio 4+ by iConnectivity which is discontinued (maybe also the Audio 4c works but I didn't try it). Second hand is quite cheap.

It works because it has two USB ports. I connect the MPC ONE to port 1 and the PC to port 2:

Can you confirm it still working on the latest firmware? I got one iConnect Audio 4+ and it start to pop/crack after 1 minute or so on firmware 3.3.0 on my Force.

I have found pop/crack issues caused by USB saturation - too much (sound, webcam etc.) trying to flow across a too narrow pipe (a whole USB hub's worth to a single USB2 port). Connecting the interface over its own host port solved it. Check that before trashing a perfectly fine interface !

Hey all,
Has anyone tried Audient EVO 16, Clarett Octopre, Clarett 4 Pre?
There's not much choice in the 8+ category. I don't wanna go for the Behringer nor Tascam 16 (noisy preamps).
Cheers.

Can confirm: Audient ID14 MK1 works fine

2 the mods

It be nice to have a complete list pinned .. for summary

Thx

Arturia audiofuse 16rig no go.
Device hard switching to 192 kHz from 44 kHz when connecting to mpc and option switch back to 44 greyed out. Mpc see it, but returns -22 error when trying to switch to it.

The RME Fireface UFX III and UCX II both work when in class compliant mode.

After a few minutes my UCX Ii starts clicking like crazy. Basically it's a crapshoot whether any class compliant interface works.

Sound Devices MixPre6 is class compliant and works, just need to select USB C mode as Audio on the MixPre.

I can confirm the Audient EVO 16 work. But you have to configure it with the PC and MAC software/driver before. You need to set it to 44.1 for sample rate. And you can configure the output while your in the software if you want. Once it's done make sure to click on "store standalone state" to save the setting to the internal memory of the evo.
Now I dont use any computer, just my MPC live 2 and the Evo16. Work like a charm (no crack and pop, no distorsion) if you set it right.
Best audio interface for now, I dont regret my motu.

@dtism - I also have a SoundDevices MixPre 6 (firmware 9.01) it works but I can only receive the first two channels from the device into the MPC. Other channels come in silent. Are you seeing this as well?
