The following effects are available:
rEVErB
Reverb simulates the natural acoustic of a real space such as a hall, cathedral, cave or other
space. It is created by a carefully-generated, dense series of small delays of the audio signal.
These mimic the sound reflections that would occur in a real space, with the sound bouncing
around between walls and other surfaces. You can use the MOD control to adjust “Room size”,
to simulate the effect of different spaces.
dELay
Delay is when the audio signal is repeated at a later time. The delayed signal creates an echo
effect. Use the MOD control to vary ‘feedback’; this loops the delayed signal back into the input
of the processor and makes the original signal repeat several times.
LPf (Low Pass filter)
Akin to a tone control, the Low Pass Filter removes the upper part of the audio frequency
spectrum, allowing only frequencies below the ‘filter cut-off point’ (adjusted with DEPTH) to
pass. Varying the DEPTH produces a characteristic “sweeping” effect, which can be enhanced
with Resonance, adjusted with the MOD control. A very low-frequency modulation can also be
applied with the X control, which varies the filter frequency, creating a “wobbly” sound.
fLanGEr
The flanger effect is created by mixing two identical sound sources together, one of them
being slightly delayed relative to the other. The delay itself may be dynamically varied at a low
frequency, this is adjusted by the MOD control. The delay is adjusted with the X control.
PHaSEr
The phaser uses a series of moving, narrow-band filters distributed across the audio spectrum
to create the characteristic “whooshing” sound associated with this classic effect. A low
frequency oscillator controls the speed of the sweep (varied by the MOD control), and the
“width” of the filters (the range of frequencies over which each is effective) is adjusted by the X
control.
HPf (High Pass filter)
The High Pass Filter acts in an identical manner to the Low Pass Filter, except that it rejects low
frequencies and passes high frequencies. The controls have the same functions.
cruSHEr
The Crusher is a digital effect which reduces the bit rate of the audio, reducing resolution. It
also adds distortion. This results in a sound with a “grainy” quality which can be either glitchy or
overdriven.
EcHo
Similar to Delay, Echo repeats the original signal a number of times (depending on the setting
of MOD) before the echo trail dissipates. It emulates classic Tape Echo, giving a warmer, more
analogue sound. An X parameter is available for Echo; this introduces filtering into the echo
feedback, which adds further to the analogue simulation.
