Make Noise Erbe Verb - Manual (Page 8)

Predelay (cont’d)
In addition to being wide ranging and completely independent of the Size parameter, the Erbe-Verb Pre-Delay is
also able to be synchronized to the rest of the modular system. Using the TEMPO IN (12a), it may be synced to a
division (CW from NOON) or multiple (CCW from NOON) of the clock patched to TEMPO IN (12a). This is highly
un-realistic. Nowhere in nature is the trajectory of sound synchronized to a machine. The Reverse function reverses
time by playing the Pre-Delay buffer backwards. This creates Reverse Reverberations. This may occur in nature, but
we are not yet certain. Reverse time is set by the PRE-DELAY controls (7a, 7b). Reverse may be toggled On/ Off by the
associated REVERSE Button (11c), and momentarily engaged using the REVERSE Gate IN (11b). Like Pre-Delay, using
the TEMPO IN (12a) Reverse may be synced to a division or multiple of the input clock.
The Pre-Delay parameter has a unity gain control signal input PRE-DELAY CV IN (7b) allowing for voltage control. This
also aids in morphing between spaces or creating unusual circumstances within the space such as constantly
moving the listener from the mouth of a cavern to it's depths. Fast modulation or sweeping of this parameter will
result in pitch shifting as well. Audio rate modulation of this parameter could be very pleasing, as it creates
gorgeously metallic tones. Because there is no attenuator associated with this parameter, it could be helpful to patch
the desired control source to a channel of MATHS for attenuation prior to the Pre-Delay CV IN destination.
Decay:
After Size, the most dramatic parameter on the Erbe-Verb is DECAY (10a) which changes the length of the reverb
"tail," from very short all the way up to infinity. In some ways this control is similar to the FEEDBACK controls on the
ECHOPHON and other Echo or Delay processors. Decay uses internal feedback to put energy back into the reverb
algorithm, resulting in sustaining the reverb. This sustaining increases the time it takes for the reverberations to
settle, or decay to zero amplitude. Decay is by nature a function of Size. Smaller spaces tend to have shorter Decay
times while Larger spaces tend to have longer Decay times. Some typical Decay settings for example:
Coffin: 9 o' Clock
Room: 12 o' Clock
Plate: 1 to 2o'Clock
Hall: 11 to 2 o' Clock
Ambient: 11 to 2 o' Clock
Heaven: Full CW
Directly beneath the DECAY Panel control are the DECAY CV Attenuator (10b) and DECAY CV IN (10c). Use the DECAY
CV IN (10c) to modulate the Decay parameter. This allows for morphing between spaces or creating spaces where
the energy is fluctuating. Use the DECAY CV IN (10c) to create more subtle modulations. Because the Decay
parameter is feedback based, the response will be slower then that of the Size or Pre-Delay parameters. Therefore
greater impact will be achieve with slower control signals such as envelopes from MATHS or Function w/ long Rise or
Fall settings, LFOs from MATHS or Function, slower random voltages from the Wogglebug (Smooth or Stepped) and
sequences from Pressure Points that are clocked at a division of the master clock.
