Mock up scenario : linking 2 or more X1 daw

If all you want to do is record the Midi data then you can plug in as many midi interfaces as you need.


If you're recording the audio from the midi keyboards then the standard method is to ensure your interface has enough inputs to match your requirements. For example, the PreSonus Firestudio I use can handle 24 analogue inputs (with adat extenders) and the driver supports chaining 2 of these together, so I could record upto 48 chanels (if I had the money...)

Slaving two or more seperate audio interfaces in ASIO mode is impossible. ASIO doesn't support it.

Running 2 independent systems, linked by MMC would theoretically be possible, but they MUST share a common word clock for the audio interface to ensure the data rate on both machines is exactly the same.   DAWs normally take their timing clock from the interface (or external clock) and no 2 pieces of electronics will run at exactly the same speed, unless they're liked.  You'd find that transfering recorded tracks from one machine to the other for mixing that they gradually drift out of time with each other.
