The DELAY function is available in all presets.
Delay is a reproduction of the input signal, occurring at a prescribed time (usually
expressed in milliseconds) following the input signal. The Voodu Valve™ provides two
discrete delays (Delay 1 and Delay 2), each of which has its own parameters to deter-
mine its particular characteristics.
The PARAMETER SELECT control will allow you to access these DELAY parameters:
DELAY Function
DELAY
MUTE TYPE
DELAY LVL
MIX
The DELAY parameter determines whether the Delay is active or
muted for the current preset.
The MUTE TYPE parameter allows for muting the delay at its input
(PRE), its output (POST) or BOTH.
Muting the input (PRE) of the delay will not allow any signal to enter
the delay section until the delay is switched in. When using a moderate
amount of regeneration, switching out the delay with the input muted
will allow you to generate a non-delayed signal which will play over the
decaying regenerated signal which continues on after the delay is
switched out.
Muting the output (POST) of the delay will result in the delayed signal
being immediately turned off when the delay is switched out. This
means that delays and regeneration will not continue when the delay is
switched out. If the output were not muted, signals that were input
before the delay was switched out would be allowed to regenerate, even
after switching out the delay.
It is also possible to mute both the input and the output (BOTH) so that
no signal enters or exits the Delay section when it is not switched in.
The DELAY LEVEL parameter determines the overall level of the
delayed signal at the output relative to the direct signal and other effect
signals. This parameter can also be accessed from the Delay function
parameter list.
The MIX parameter is used to define the ratio of Source 1 signal to
Source 2 signal to be input to the Delay section. Source 1 is the Voice 1
output from the previous effect in the signal chain (chorus, flanger,
pitch shifter, etc.), while Source 2 may be the Voice 2 output from the
previous effect in the signal chain or the direct signal (selectable via the
SOURCE 2 parameter).
In configurations where there is no effect immediately preceding the
delay, Source 1 and Source 2 will be the preamp output (direct) signal.
