Using both external and internal inputs

Is it possible to use my scarlett 18i20 external USB device (8 channels) and my internal m-audio delta sound card (4 channels) at the same time? It looks like under the hardware setup you can only select one type at a time. Thx!

If you are using ASIO drivers, then no - it's not allowed under ASIO rules; nothing to do with Audition. Only one device is allowed to punch a hole clean through the OS at a time. If on the other hand you wish to severely compromise one or other sound device, then if you use ASIO4ALL you could sort-of aggregate them using what is effectively MME, only it doesn't look like it to Audition. Trouble with this (apart from the latency increase) is that one of the two devices has to be re-sampled by the OS in order to sync it to the other. And OS resampling is seriously crap.

 

So in sensible terms, no.
