Need a simple, rock-solid interface.
I'm using a Mac Pro with Mountain Lion and crashing my audio drivers a lot in both Logic and Studio On, and Final Cut Pro X as well. My main interface is a Tascam 1641, which I like a lot, but the drivers are horrible, and I have to power cycle it frequently and/or restart the DAW.
I also have a Tascam US-800, but the drivers are even worse and it often simply disappears from the system. I also have some old Midman USB stuff but it's noisy as hell and I only use it in an emergency.
The 1641 is pretty much perfect for my purposes in other respects -- the multiple outs and back panel inputs are useful for laying out and back to a 2-track.
What's the answer?
