Ok, I've been researching different hardware and I'm still having a hard time trying to decide what to go with. I'm liking the Presonus Firepod. If I had two of these linked together, I could track 16 chanels of audio (my goal is 12... full drum set and some scratch tracks). My question is, if using the two Firepods, how could I set up multiple headphone mixes for the musicians? I have been looking at the Mackie Onyx 1640 16-Channel Mixer thinking that I could use this instead of the Firepods and create mixes with the aux's. What do y'all think of that idea? Somebody please help me. I've got projects on hold and i need to start making some desicions pretty quick. Thnks!
