Rather than modelling an amp, it's basically modelling a bass recording chain... it splits the signal into two, high passes the mids, adds distortion and filters it with a cab IR. The low pass stays clean and gets compressed. The two are then blended back together, then fed to FOH.
I mostly hear my rig through my IEM, however I have the IR shut off on one of the Infinity's outputs, which feeds the blended distortion into my stage amp, which is a real bass rig.
Bass has been doing this for decades. This is basically a more hi-fi version of what a SansAmp BDDI has successfully been doing since the early 90s, only it gives me more control over what's happening at various stages.
Bass for some reason has gotten a lot more attention recently. Instead of a guitar pedal with a blend knob it's been getting dedicated products designed for it. As such, there's been more emphasis on retaining and controlling the low end while enabling processing of the midrange, and I don't need a small wall of amplifiers to accomplish it.
Normally you only see this level of complexity in a bigger pro level rig, however I was about a half step away from doing this using an all analogue path when I figured I'd experiment with doing it digitally first. I have to say, this is a big step up. That I can do it all in the box for a fraction of the expense is alluring, as is only having one XLR to hand the soundman.
