Interested to purchase the standalone version (for soundchecking before the gig) but from the manual i cannot find out: 

- Can I select multiple audio inputs (= usb audio interfaces) ? How?

- Within a selected audio input, can i select multiple channels simultaneously? How?

My purpose is to analyse up to 12 channels for loudness - frequency range - coming from different audio interfaces or from the mixer (zoom L12)

Thanks for feedback..
