P8 The Reverb LOW DECAY Parameter
This Parameter subtracts low frequencies from the Reverb Decay (Page 6) so that
they fade out more quickly than the higher frequencies. This Parameter can make the
Reverb Effect sound brighter if set to a Value higher than the High Decay Parameter.
Higher Values will cause the low frequencies to fade faster. Lower Values will cause
the low frequencies to fade more slowly and affect the overall Reverb Decay less.
To adjust the Reverb Low Decay Value, move the cursor beneath the Value and then
turn the Value encoder to set the desired amount:
REVERB(Large)
Low Decay: -2 0
P9 The Reverb HIGH DECAY Parameter
This Parameter subtracts high frequencies from the Reverb Decay (Page 6) so that
they fade out more quickly than the lower frequencies. This Parameter can make the
Reverb Effect sound darker if set to a Value higher than the Low Decay Parameter.
Higher Values will cause the high frequencies to fade faster. Lower Values will cause
the high frequencies to fade more slowly and affect the overall Reverb Decay less.
To adjust the Reverb High Decay Value, move the cursor beneath the Value and then
turn the Value encoder to set the desired amount:
REVERB(Large)
High Decay: -4 0
Tip: Generally high frequencies fade faster than low frequencies. To make your
Reverb Effect sound as authentic as possible, set your High Decay to a higher
value than the Low Decay, generally by as much as a factor of 2.
P10 The Reverb DENSITY Parameter
This Parameter affects the actual timbre of the Reverb Effect. Higher Values will
increase the number of short echoes that compose the Reverb Effect, while lower
Values will decrease those echoes. The result is perceived as "thicker" reverb. High
densities are usually desirable on drum sounds, whereas lower densities are usually
desirable on vocal and guitar sounds. Generally, the lower the density, the more
transparent the Reverb Effect becomes.
To set the Reverb Density Value, move the cursor beneath the Value and then turn
the Value encoder to adjust the density of the Reverb Effect:
REVERB(Plate1)
Density: 8 0
