Using two Akai Midimix simultaneously?

Good morning all,

Im using cubase 7 and currently have one Akai midimix which I use for live mixing of tracks. Its absolutely fantastic but… I need more channels.

Does anyone know if I can buy a second one and run them side by side (in essence to create a 16 channel midi mixing desk without having to use the bank functions)? Obviously, I don’t want to spend the money on a second one only to find out I can only use one at a time!

Thanks in advance for any info!
