VB-Audio's Forums

Hi

I'm on Windows 10.
I have a MOTU Ultralite-mk4 sound interface.

The MOTU drivers have a "Out 1-24" WDM device that I can select in all the standard windows applications like Chrome, Spotify, Skype etc. etc.

The problem is, that all the applications send sound to channel 1-2 of that device.

What I would really like, is a way to create some virtual audio devices, such as "Motu 3-4" that I can select in f.ex. Spotify, and then the audio sent to that output would be routed to channel 3-4 of the physical "Out 1-24" device.

Is this possible using either Voicemeeter, or other VB-Audio applications?

Hi. Voicemeeter can use any of the 24 outputs provided by the ASIO driver for your interface. These instructions apply to VoiceMeeter Banana (You can also use Voicemeeter Potato or even Standard version);

• Select ASIO: MOTU at Hardware Out A1
• Open Voicemeeter Menu > System Settings / Options... window
• Under OUT A2 use PATCH BUS TO A1 ASIO Outputs to patch outputs 3 and 4 clicking the small boxes
• Using Windows Sound Settings - App volume and device preferences, select VoiceMeeter Aux Input as the Output device for Spotify
• In Voicemeeter turn on A2 for VoiceMeeter AUX VAIO

Hope this helps. Let me know if you need further assistance with your setup.

Some USB Audio Interfaces include one option to split the outputs in Windows. Maybe you can also ask MOTU Support to see if there is an option to split the 24 channels into 12 stereo pairs (Some of them are named WDM 1-2, WDM 3-4 etc in Windows)

Thank you. That's a very good tip about the patch bus!

And as you mentioned, it turns out there was a secret registry setting that makes the MOTU driver create X amount of stereo pair in/outputs, so that's what I ended up going with, but this is certainly useful in any case
