39 REVERSE REVERB 1
REVERSE REVERB 1 produces a reverberation that gradually increases, simulating a backwards
sound with a maximum duration of several seconds. When a signal enters this algorithm, the
plate reverb (from which this algorithm is derived) is almost instantaneously turned on, and then
the output volume is ramped up. This algorithm will only trigger one time. REVERSE REVERB
1 is triggered by an input signal level (THRESHOLD) determined by the user. Once triggered,
the reverse envelope will proceed to completion, and ignore subsequent trigger levels. If you are
looking for a reverse effect that will retrigger, try using REVERSE REVERB 2. The topology of
the Reverse Reverb is similar to the Plate Reverb. The FX-1 and FX-2 MIX parameters offer
different dry/wet mixes.
HF DAMPING Range: 00 to 99
This parameter sounds best when it’s set to low values. It has the same function as in the Plate
Reverb, which is to filter out more and more high-frequency energy. For the most natural
sounding reverse effect, we recommend a setting of 00.
DEFINITION Range: 00 to 99
DEFINITION controls the rate at which echo density is increased with time. If set too high, the
echo density will build at a rate that exceeds the decay rate. This can be used for a special effect.
DIFFUSION-1 Range: 00 to 99
DIFFUSION-1 smears the input signal making a smoother sounding reverb. Controls the high-
frequency ranges. For percussion sounds, high values are recommended.
DIFFUSION-2 Range: 00 to 99
Similar to and in series with DIFFUSION-1, this parameter controls lower-frequency ranges.
RELEASE
TIME
ATTACK TIME
HOLD TIME
LEVEL
TIME
ATTACK Range: 1 msec to 10.0 sec
Sets the duration over which the reverb builds. It is recommended that you set this value less
than the HOLD time.
HOLD Range: 1 msec to 10.0 sec
Controls the amount of time that the reverse envelope will sound after it has been triggered.
Rule of thumb: don’t set the HOLD time much longer than the ATTACK time.
RELEASE Range: 1 msec to 10.0 sec
Determines the release time after the HOLD time has elapsed. Generally this time is very short.
Lower values offer an abrupt cutoff.
SLAPBACK - TIME Range: 0000 to 0500 msec
Controls the delay time of an internal dry signal to create a slapback. This effect helps to simulate
a backwards reverb, since now the dry signal appears at the end. In general, we recommend the
FX Mixes be set all wet (99) for this effect. Rule of thumb: set this parameter at about the same
value as the HOLD time.
