Bruce! Good grief! How are you? My favorite gravelly voice.
I'll take a look at RME. Anything in particular? As I said this is just for a guitar and a keyboard. I'll go a bit cheap on this because if I need something more expensive in the future, when there will be new gear out and I'll have a clearer idea what might be needed then, and I won't see whatever I buy now as a wasted expense. I've bought plenty of stuff in the past that I didn't really need to. Should have instead spent the money on drugs and prostitutes*.
But hey, not too cheap!
*Yes, that was a joke!
