In & Out to Computer at the same time?

I've been running backing tracks through the T4S's digital input.  I want to record the mix of that plus the other inputs.

Would it work to send Master Out to USB while also using USB for two channels of in?

Ideally, I'll use different devices for in and out.  If I attach the T4S to a USB hub, can I do that?

Hi, Peter.

That's an interesting question.

I did my testing with Audacity.

This works on my Windows PC but only when I assign USB B from PC to channels 3 and 4. It won't work when I assign USB B from PC to Master.

Notes: USB B from PC

I think this is because I have the USB B to PC set to send Master. I didn't try assigning the USB B to PC to specific channels because that wouldn't serve your purpose.

I don't have a way to test this. If you try it, please let us know what happens.

Thanks for trying the experiment.  I'll try to mock something up with a hub to see what happens.  I'll post what I learn.

Hi Peter,

"USB has a strict "tree" topology and "master-slave" protocol for addressing peripheral devices; peripheral devices cannot interact with one another except via the host, and two hosts cannot communicate over their USB ports directly."  -- Source: Wikipedia USB

This looks like you are connecting the slave (T4S) to two masters (recorder and backing tracks).

I'm interested to see what you find.

Thanks,
