I just bought this audio interface to use in conjunction with my laptop and whatever hardware I end up adding: probably a midi controller, mic, guitars, perhaps an MPC, etc...Anyone using this? If so, what for? Any tips on making the most of it? Here is the unit I am speaking of: http://www.bhphotovideo.com/c/product/421024-REG/Edirol_Roland_UA_4FX_UA_4FX_Audio_MIDI_Interface.htmlhttp://www.xanga.com/jessewarren/
