I've recently been toying with the idea of using my laptop live for the same reasons everyone else is bypassing amps: Misha did it (kidding!) I'm just sick of having a stage sound that sucks because of sound engineers that don't particularly care for their jobs and I'm pretty fond of the tone coming out of Amplitube's SLO model. I've tried googling all this stuff but there's not a lot out there and that stuff that is just confuses me further. My uncertainties are thus: I want to have the left channel going straight to the FOH (should be no bother, just a balanced 1/4" to male XLR cable that I can just plug in to the XLR lead that would normally mic up the amp, right?), but also another signal with no cab impulses going into the effects return of my amp. Will I need a re-amping box for that? Some people on some online forums seem to think it's necessary, others say that - because it's going in the back of my amp and not the front - that it shouldn't be necessary. I don't mind buying a re-amp box if I need one, but I don't really want to shell out if I don't have to. Thanks in advance guys.
