And next I'm going to add another sound input - from Soundboard or some kind of sound cue software. Hopefully that won't break the camel's back. Recording two podcast hosts via the Mbox 3m and recording a Skype caller simultaneously. And we can all hear each other without echo or delay.
Protools LE: it's open and i have my two mic recording buttons selected (actually I just tested this with one mic coming in so far, to be honest).
