List of Working/Non Working Class Compliant USB Interfaces

I'm using a Audient ID14 interface paired with Behringer ADAT 8200 for more audio inputs for my MPC LIve 2 standalone unit. All my inputs are working but the only output giving out audio signal is the main 1/2 output channels which I have connected to my speakers. I get no audio going out on all other output channels besides the main 1/2. I'm trying to route audio out of channel 3 into my Hologram Microcosm to record on channel input 5. Does anybody know how to get the output 3/4 to send audio on my Audient ID14 interface to work with the MPC Live 2 standalone unit?

The ID14 is a 10 channel in (2 analog, 8 digital), but essentially only 2 output channel interface.
You may setup a cue mix in the ID14 control panel to the headphone as a 2nd output pair, but I‘m not sure if you can route an independent source that way.
(I have an ID22 and iirc this was possible, but the ID22 has more outputs by nature)

the Audient ID14 has 4 outputs on the back and only output channels 1/2 are sending out audio.

Seems the Mark 1 originally had 2 outs , and the Mark 2 now has 4 outs.

Anyone have experience with Scarlet 2i4 gen 1 ?

is anyone still using their MX-1 with the most current MPC firmware 2.13? just picked up one today but can't get my MPC One to recognize it as an audio device (set the MX-1 sample rate to 44.1, set to Ext, have tried plugging it into each of the four USB inputs but still no dice).

The Aira line is infuriatingly so close to class compliance - they even offer multitrack over USB but it just had to be with the proprietary twist of Roland drivers. Were they too early to have been developed on a mature specification ?

apparently the trick is running USB-B OUT of the MX-1 into the MPC USB-A (which seems counterintuitive but now working)

Does that make the MPC see the MX-1 as a class-compliant USB interface ? That would be sweet because I currently have a medium-term desire to get a MX-1 to play live with the kids on a bunch or Aira-appropriate (pun intended) gear such as TB-3 and a TR-8 (not the S version - I'm cheap and I have a MPC) and the plan is to send MPC audio through an USB interface to the MX-1's S/PDIF input.

Offtopic, the RC505 mkII isn't Aira-compatible but it does send audio correctly to the MX-1 through USB - though MIDI has to go across a MIDI cable because lack of RC-505 mkII Aira compatibility means USB to the MX-1 doesn't carry MIDI.

essentially. what it allows is for the MPC to route internal drum programs, plugins, keygroups, submixes even i suppose, to the five digital stereo channels of the MX-1, i.e., the Digital channel = Out 7/8 on MPC, USB 1 = 9/10, USB 2 = 11/12, USB 3 = 13/14, USB 4 = 15/16, and the PC channel will output the MX-1 master mix back into MPC via USB audio if needed.

That looks like the MX-1's "EXTERNAL MIXING MODE" where "18 channels of USB audio output are assigned to the faders" making it a DAW control peripheral (its default is the standalone "MIXER MODE"). Interesting synergy with the MPC, apart that I don't see where to get a digital output of the stereo master to a recorder (PC, portable recorder - whatever) - as the MPC's audio track recording cuts off at 5 minutes.

Of course the MPC can export the final mix from song mode, but the point of an Aira setup is live play - so that doesn't fly... For studio work, no need for TR-8, MX-1 & co: the MPC is all I need !

Also, recording the MX-1's main out from the aux send cinch pair is of course possible, but that would sacrify a major benefit of the MX-1 - which is the fully digital audio path.

RME Fireface UCX II works in CC mode.
Neumann MT 48 does not work. I have put in a request to see if there is a way to put it into CC mode.

The MPK 25 (2009 version) works pretty well with the MPC X SE and MPC One.

Has anyone gotten error: could not get PCM hardware configuration from device. Code: -22. I spoke with Neumann and they said that the MT48 is class compliant, but I keep getting this error whenever selecting the device.
