Time-based effects (time FX)
Alongside frequency-modulating effects, Neuron
features another effect processor offering various
time-based effects (time FX). This effects group is
equipped with a dedicated on/off switch: the time
FX button.
Like for freq FXs, the two most important effect
parameters are variable via stick, if you set the
parameter level to time FX.
Time FX parameters are explained on page 142.
Stereo spread
This effect delays one of the two stereo channels to
create a wider stereo image.
LR delay
Delay is a variable time-based parameter used to
start an event, in this case a signal, only after a
predetermined amount of time. You can vary delay
time within the defined limits. Delayed signals are
routed back into the effect’s input. This is called a
feedback circuit or loop. The signal is then routed
back to the output with a variable number of
repetitions or echoes contingent upon the amount of
feedback signal (as determined by the feedback
parameter).
Phaser
A phaser colors the sound of a signal and modulates
it periodically.
Here is a somewhat simplified explanation: The
incoming audio signal is doubled and one signal is
put out of phase using special filters. Then the out-
of-phase signal is delayed ever so slightly and added
back to the original signal via a feedback loop.
Superimposing one signal over the other generates
frequency cancellations. In other words, certain
frequencies are wiped out of the sound, which is
clearly audible.
The filter frequency determines which frequencies
are cancelled out. This special filter causes phase
shifting, so if you change its center frequency, the
effect changes and you will hear other frequencies
being cancelled out.
This is where the aforementioned periodic
modulation comes into play: If you modulate the
filter’s center frequency via an LFO, the phase
shifting and frequency cancellation driven by the
LFO oscillation changes periodically. The LFO’s
frequency, amplitude and waveform are variable,
creating different filter frequency modulations and
thus very different sonic results.
