My CME UF80 does not want to get along with B5. It's hardly the best controller for organ, but it's my primary controller at home and I would have liked the option of using it when I didn't want to take the time to switch. It's clearly a new problem with the CME as it appears to have quit responding to "Pedal B" altogether regardless of how I set it or how many factory resets I try
FWIW: The sound of this thing is smokin' imho, but I agree that the Leslie sound, while very authentic, might occasionally be a little too "roomy" for some songs. I've found a workaround though. If you place a transient tamer after the B5, you can dial back the room sound. I put UAs SPL Transient Designer in the effects chain and it works brilliantly.
