•
Ping pong: echoes are generated alternating left and right channels.
−
Delay (ms): sets the time (in milliseconds) between one echo and the following one
−
Feedback: sets the magnitude of the feedback signal, and therefore also the decay time of each echo
−
Hi Damp: sets the cutoff frequency of a low-pass filter. This filter dampens the echoes with a frequency higher than
the cutoff. Assign a relatively high value to this value in order to imitate analogic delays, with warmer and milder
repetitions.
−
Dry/Wet: balance between the original input signal (slider to the left) and generated echoes (slider to the right).
CHORUS
Chorus is a modulation effect which adds to the original signal a slightly
modified copy of it. The copy is slightly and cyclically detuned. The resulting
sound is "thicker" and more spatialized than the original.
−
Type: select the Chorus type,
•
Chorus 1: with one modulating signal.
•
Chorus 2: with two modulating signals in antiphase.
•
Chorus 3: with four modulating signals creating an antiphase
between the left and right channels, with different speeds.
•
Chorus 4: with four modulating signals, each with its own phase.
−
Depth: sets the modulation depth.
−
Speed (Hz): sets the modulation speed in Hertz.
−
Delay (ms): set a delay time (milliseconds), after which the effect starts modulating.
−
Dry/Wet: balance between the original input signal (slider to the left) and completely modulated signal (slider to the
right).
FLANGER
The Flanger effect is similar to the Chorus; the only difference is that the
Flanger elaborates and develops further the signal.
−
Type: select the Flanger type,
•
Flanger 1: with one modulating signal.
•
Flanger 2: with two modulating signals in antiphase.
−
Depth: sets the modulation depth.
−
Speed (Hz): sets the modulation speed, in Hertz.
−
Delay (ms): sets a delay time, after which the effect starts the modulation.
−
Feedback: sets the quantity of signal to send back to the effect input as feedback; in this way the elaboration
development of the signal can be controlled.
−
Hi Damp: sets the cutoff frequency of a low-pass filter; it makes the modulation softer and dampens the effect.
−
Dry/Wet: balance between the original input signal (slider on the left) and processed signal (slider on the right).
VIBRATO
This effect modulates the frequency, producing a periodic tone variation; the
length of the oscillation period and the modulation magnitude can be
adjusted.
−
Type: select the Vibrato type,
•
Vibrato 1: with one modulating signal.
•
Vibrato 2: with two modulating signals in antiphase.
−
Depth: sets the modulation depth.
