Alright, I'm pretty sure I've heard of this before, I just don't know what it's called or any specific programs that do this. I'd like to know if there is a program that you can run you bass into your laptop via an Interface, into a program to give you effects, and then back out of an output on the interface and into your amp or the PA. So essentially, your laptop computer is your pedal board. Is there such thing? If there is, could you recommend me a few good ones? I use a Mac, by the way. Thanks Edit: I'm looking at buying Propellerhead's Reason. Is there a way to set that up to do what I'm trying to do?
