Width—has a less noticeable eect. But it can be heard. It seems to add lower frequencies. Level—is the overall loudness of the reverb. Paul observes that there is a certain “tubbyness” to Fluidsynth reverb with early reection, an eect like shouting into an empty milk tank or shouting in an empty house with hardwood oors, and that some registrations sound better with Fluidsynth reverb than others.
