Differences between a POD and TonePort?
Maybe this is a trick question. The TonePort is a guitar interface, you can manipulate the sound in the computer for recording, and I think the TP comes with recording software, not sure. The main function of the thing is to get sound into the computer.
The POD is a multi-effects unit. It doesn't need a computer as far as I know. It provides amp and cab simulation and some effects, presets and a tuner. I think it's a different animal, but many effects units include a USB output so I guess I know where you're coming from.
I'm considering recording some stuff so I was looking into a POD too for its USB capabilities, now, I'm considering a Boss unit, but I went through all those M-Audio things just trying to understand what they do! lol
