This control adjusts the reverberation time of the independent reverberator. The
range of action is limited. Be careful — both long and short reverb times may
sound unnatural. If a much longer or shorter reverb time than the preset provides
is desired, SIZE should be changed first.
SIZE allows you to vary the apparent size of the space over a wide range. SIZE
is the most dramatic control, and must be selected to match the music or program
material. It should be the first control that you adjust to tailor the desired space.
SIZE also affects the reverb time, in a similar way to the standard reverb
programs.
DIFF controls the degree to which initial echo density increases over time. High
settings of DIFF result in high initial buildup of echo density; low settings cause
low initial buildup. Echo density is also affected by SIZE; smaller spaces will
sound denser. To enhance percussion, use high settings of DIFF. For clearer,
more natural vocals, mixes, and music, use low or moderate settings.
ROLL sets the frequency above which a 6 dB/octave low-pass filter attenuates
the processed signal. It attenuates both pre-echoes and reverberant sound.
High frequencies are often rolled off with this parameter, resulting in more natural
sounding reverberation.
