Don't know if you are wired into the discussion at the Keyboard Corner but some are struggling to get the rotary speaker sim to sound satisfactory especially on tremolo. There's something in the mid range that's causing a shrill beating sound...it's like the horn is wobbling off axis while spinning or it's interacting with some range of frequencies from the organ...it's same issue for both sim models. Was it designed intentionally to be this way? I've used the EQ to tone it down around 2K hz but I can't get rid of it. Don't want to come across as a complainer...it's a great board and I know there are always kinks to work out when one first comes out.
