List of Working/Non Working Class Compliant USB Interfaces

I don't know if it has been mentioned yet, but the Behringer Wing (Compact & Rack) work as an Audio Interface for AKAI MPC LIVE 3 und AKAI FORCEt

Hi everyone, thought it might be useful to post some info regarding a new purchase I made earlier this week.

I picked up a Yamaha MGX16 - the new MG release with dual USB (C) functionality.

After going through the very information sparse user manual as far as setup and routing I can confirm:

MPC Key 61 with USB works (using 32 Channel Mode): playback and recording - no pops or crackles
Apple iPhone 15 Pro works: playback and recording - no pops or crackles

That's both devices utilising playback and recording, simultaneously, agnostic of the source.

Routing is capable - it's possible to route analog signals and both USB I/O's where you please for the most part as there are multiple options for channels and mixes to receive inputs and map outputs.

* I can't seem to get the K61 to utilise Bluetooth Midi - everything connects, Cubasis sees the MC and I can assign the midi device and channel per track (the K61 also shows the iPhone as a Midi device in settings and on a Midi track). I will have to push further into this issue.

I'll be doing some extensive testing tomorrow but for now, things look good.

More testing:

I have routed a Deepmind 12 and UB-Xa into the stereo analog ins of the MGX.

These inputs have been assigned to 2 different mix busses - the K61 sees these MGX USB outputs, each MPC audio track is set to receive incoming signal as per below:

Deepmind 12 - MGX Analog Stereo In 9/10 - route to MG Mix 1 - MG Mix 1 route to MG USB Daw 1/2 - K61 Audio Track 1 Receives MGX USB Daw 1/2.

UB-Xa - MGX Analog Stereo In 11/12 - route to MG Mix 2 - MG Mix 2 route to MG USB Daw 3/4 - K61 Audio Track 2 Receives MGX USB Daw 3/4.

Inputs can be muted so only the return from the K61 is being monitored - or vice versa, or both.

No noticeable lag, pops or crackles - recording these analog signals into the K61 also tests the same.

Sound quality is very good, I have an RME UFX as my DAW interface and the MGX is obviously not on that level but close enough to not notice.

More inputs I will be testing:

Aston Origin JFET Condenser Microphone: connect via XLR into analog 1.
Guitar Pedalboard: Two Notes Opus at the output stage - XLR into analog 2.
TC Helicon VoiceLive GTX: stereo XLR into analog 3 and 4 (will try and setup as a send/return effect).

MGX Omni Outs: there are 8 of these - I will send stereo pairs into the UFX.

For a MPC standalone setup it seems to be working very well - crossing fingers Akai and/or Yamaha don't bork the connections via firmware updates

I was Running an MPC-One into a Audient Evo 16 with an Expert Sleepers ES-8 connected via ADAT, Output audio plays fine but there are some occasional clicks on input. It would probably be manageable except for the fact I was using the ES-8 to send all my MPC audio into Eurorack mixing it then sending it back through the MPC as a final output stage.

Given my MPC is already doing too much looks like i'm also going to try the Yamaha MGX, might keep the old setup to see if it works when I eventually upgrade to a XL when the budget allows.

Recently tried the MOTU 16A with the XL and after setting the A16 to 41.4 or 48kHz this works flawlessly and without dropouts.

Things to watch out: on anything higher than 41.4/48 the MPC will say that the interface is not supported. After switching the sample rate on the A16 I still had to unplug/replug in once. But it's working. Wish that I still could use the Akai interface for interfacing audio with a computer though

I know German Numbers sound funny to English ears, but do you mean 44.1kHz

I am sorry. You are right, that was typed in a hurry so I didn't notice my typo. Nothing to do with German numbering systems . Often enough when I type really fast I can't really control the movement order of my fingers. And if I don't proof read my shit I send the funniest messages, lel

I've read through the entire thread, but I haven't been able to find a clear answer.
Can anyone tell me if the Focusrite 18i8 1st gen works !? Thanks

Sorry no one answered you.. The answer is yes. I have a 18i8 gen one and have used it.. BUT. I think all the Focusrite have this BUT and I have not seen it being talked about here.

Even though it is class compliant, you have to set up everything with a computer. Use the software on the downloads page of the Focusrite website.

The image below shows. The Sample Rate must be at 44.1khz will not work on anything else (use the Settings button below the sample rate number). You need to set up the monitior headphones setup to get audio to monitor (like the image shows, main outs to monitor), Once all that is done. Then you go to file save and save it to the 18i8 (not to a file, although you might want to save it to a file as well to recall it)

This is important (but realize if you make changes to this screen it will be saved to the 18i8. But saving it to the hardware, then disconnecting it is a good practice.

If you hear clicks/pops/dropouts. That means your buffersize it so small, You must connect it to your computer again and click on settings and change the buffer size to a smaller size. That should take care of that problem. Realize that if you have a bunch of tracks and stuff going on you will have to have a bigger buffer, but if you are just using 2 track, you may need a smaller buffer size (lower latency) . So there is no hard and fast buffer size. Depends how hard the MPC is working.

XR18 update for the list: works, 44.1 kHz only — BUT disable SYNC on the "XR18 MIDI 1"
output port (Preferences -> MIDI -> Output Ports), otherwise audio starts crackling as soon
as the MPC is under project load and won't recover until a power-cycle. Details and
explanation here:
