Input problem. (2 usb controllers to record at same time)


Recommended Posts

Hi all,


Just new to logic pro x and i'm trying to record through my Edirol UA25 (pre amp with mic), and my iRig guitar simultaneously through 2 usb ports on my macbook pro.


I have tried other posters suggestions in other threads of setting the channel numbers different etc. But i can't seem to figure out how to get them both to work at the same time.


Any help is much appreciated and apologies for the noobness of my question.


Thanks in advance.

Hi Farnerud!


What do you mean by "simultaneously through 2 usb ports"?

Isn't the iRig connected via the headphone output?


Anyway, what I think you need to do is to create an aggregate device.

Follow this procedure and come back if you have any more questions:

Click this link to your signature and add your system information:

• Logic version and sub-version (e.g. Logic 10.0.6)

• Computer (e.g. MacBook, Mac Pro, iMac)

• Processor (e.g. 2.2 GHz Intel i7)

• Memory (e.g. 8GB)
