Im planning to automate the patch changing of both mine and my band's other guitar player's POD X3 Live. I know this needs to be done by sending midi commands. So here is what i am planning: I plan to buy a new audio interface (Profire 2626 or Firestudio or Saffire Pro 40) that i will be using live with a laptop. The audio interface will have just 1 midi in/out so how will i connect two of our POD X3s? After thats done, i will have to send midi commands through the DAW (i use Cubase, Nuendo) at particular sections of the song when i want the two POD X3s to change patches. How is that done? This is basically what Tesseract does too at their gigs. I am completely new to MIDI.
