On my Prime 4 with Engine 3.2.0, I discovered some unexpected behavior with the reverse verb effect. Unlike all the other effects, it is routed pre-key lock. So, if the effect is (fully) wet and the pitch fader is not at the zero position, the pitch of the audio is still higher or lower, depending on the pitch value.
Thanks for noting this. If you’d like to escalate this and note it submit it here: Submit a ticket : Denon DJ
Thanks for the quick reply. I just submitted a ticket.
