• Pre-delay: See room/reverb
• Size: Size of the virtual reverb plate
• Buildup: Low values result in a fast reverb increase. If the value is greater, the activation
phase increases.
• Decay: Reverberation time, see room/reverb
• Damp freq/Damping: See room/reverb
• Width: See room/reverb
• Modulation: Slightly alters the pitch by automatically varying the internal delay times,
comparable to a chorus effect. This can reduce possible resonance; however,
depending on the material (e.g. vocals or piano) it can have a negative effect on pitch
modulation.
Retro
As already indicated above, VariVerb Pro also features vintage-style algorithms, in addition
to realistic synthesis, which are still used by many well-known manufacturers today. The
processes applied already have the highest-possible "dispersion" at the start of the reverb
phase and generate a dense, wide sound. This is highly unrealistic, since discreet
reflections can at most be detected as "fluttering echoes". In the past, various
manufacturers have attempted to tackle the often very brief repeat loops and static
patterns resulting from insufficient memory. An interference occurs, which again adds
charm to this algorithm.
NonLin
These (non-linear) models are the only ones without a real counterpart in VariVerb Pro.
Non-linear reverb is based on a sequence of individual delay blocks (so-called bursts). By
weighting these blocks you can create envelopes. Two of these typical envelopes are
"nonlin gate" and "nonlin reverse". You can use the following:
• EQ low/high: see room/hall
• Pre-delay: see room/hall
• Size: The size of the individual "bursts" i.e. the length of the total reverb summed up.
• Diffusion: Smoothens the reverb effect. The greater the value, the more echo blocks are
blurred and the more reverb occurs.
• Width: See "room/hall"
Please note that no decay parameter exists for these models, i.e. there is no "decay".
Spring
You may be familiar with reverb spirals from guitar and keyboard amplifiers. At the bottom
of these amps, a unit consisting of two to four spirals is mounted on a vibration-free
carriage. Like the reverb plate, it uses systems for transforming the electric signal into a
mechanical one and the other way around. There are different designs and sizes of spring
reverb; however, they all have the same quite peculiar sound: the typical "bloing" sound
when the springs are moved, similar to splashing. When the reverb dies away, the basic
pitch of the spring(s) can usually be heard quite clearly. Furthermore, the frequency range is
considerably limited due to the losses in the spirals and used pick-up/transmitter.
Nevertheless, or maybe for this reason, their sound is special. Some music styles such as
dub & reggae would hardly be possible without reverb.
