Love to hear these out-of-the-box applications. I don’t know that there’s a straight-up method for bi-amping, even using Dual Processing. Or using up both slots with the EQ / Compressor. Maybe one or both sides, out the Inserts? Sorry, I’m not in front of the H90, so I could be wrong here. Spit-balling ideas …
My first thought for a workaround would be using Sculpt in Split Mode, with or without minimal Low- and High-Drive. Upsides are setting the crossover point, isolating lows & highs, limited mixing + Low Boost, distortion option, bonus compressor and envelope filters. Downside is that Sculpt will always occupy 1 of the 2 slots.
