P5 The Reverb PREDELAY MIX Parameter
This Parameter allows you to mix in the amount of Reverb that is immediately heard
with the set amount of Predelay, essentially lessening the predelay effect while still
keeping it as a part of the sound. Essentially you are sending two signals to the
Reverb: a dry signal (no predelay) and a delayed signal. The Reverb Predelay Mix
Parameter mixes between those two signals.
The display shows the two signals, dry (called
number between them. If the Value is set to anything other than 00, an arrow will
point to which signal is being favored:
REVERB(Large)
PreMx:IN25>DEL
In the above example, the Predelay Mix is set to favor the predelayed (
over the dry (
For a perfect balance between the predelayed and dry signals, set the Predelay Mix
Value to 00. For the maximum predelay effect, set the Predelay Mix Value to
. For no predelay effect at all, set the Predelay Mix Value to
IN99>DEL
P6 The Reverb INPUT FILTER Parameter
High frequencies decay very rapidly in acoustic environments. When programming
convincingly realistic reverbs, it is often desirable to limit the amount of high
frequency that is processed by the effect. To that end, the DM Pro includes a low pass
filter at the input to the Reverb Effect, which reduces the amount of high frequencies
that are processed by the effect.
To set the Reverb Input Filter Value, move the cursor beneath the Value and then
turn the Value encoder to set the amount of filtering you desire:
REVERB(Large)
Inpt Filter:5 2
Lower Values allow less high frequencies to pass into the Reverb Effect (more
filtering), and higher Values allow more high frequencies to pass into the Reverb
Effect (less filtering).
Tip: As you filter out more high frequencies with the Input Filter, the perceived
Reverb Volume will be softer. If you set the Reverb Input Filter Value relatively
low, try turning the Reverb Volume up to compensate for the psychoacoustic
level difference.
P7 The Reverb DECAY Parameter
This Parameter sets the length of the Reverb Effect, which is often associated with the
size of the environment that you are simulating. Higher Values simulate a larger
environment, and lower Values simulate a smaller environment.
To set the Reverb Decay Value, move the cursor beneath the Value and then turn the
Value encoder to set the length of the Reverb Effect:
