Any chance you'd share that patch Cliff? Sounds great! Interested in how you are using the rotary effect.
I didn't save it. Not much too it. All knobs at default on the amp block. I used the 2x12 Double Verb Mix and 2x12 Double Verb M160 (UR) in stereo with 0.05 ms offset on the first one. I should mention the beta firmware allows UltraRes cabs in stereo now.
I set the Rotary slow and with a low mix. The Depth parameters were set pretty low as I was trying to emulate a Fender Rotothingy (forget what they're called). A tiny bit of Delay and then the Reverb. Everything in series.
I only put a couple minutes into the patch creation. I think people overthink it. Just grab the amp model you want, pair it up with some appropriate cabs and go. Adjust the desired gain and level and play.
