DELAY/ECHO
This is a sound effect that consists of the repetition and modulated delay of a sound signal.
Once the signal has been processed, it is mixed with the original, resulting in the classic
sound echo effect. PARAM 1 regulates the FILTER, which allows you to attenuate the high
or low-frequency ranges of the signal. PARAM 2 controls the FEEDBACK, i.e. the number
of times that the signal is repeated. With the TIME UP/DOWN buttons, you can adjust the
time of the delay from 1:8 to 4:1.
PING PONG DELAY
This effect is similar to one described above except that the right channel lags slightly
behind the left channel. PARAM 1 controls the STEREO, and PARAM 2 regulates the
FEEDBACK, i.e. the number of times that the signal is repeated. With the TIME UP/DOWN
buttons, you can adjust the time of the delay from 1:8 to 4:1.
PHASER
This is a sound effect that consists of an all-pass filter, varying over time, that works by
modulating sections of signal that are out of phase with each other and then re-mixing the
processed signal with the original signal. These frequencies are modulated with a low
freque
ncy oscillator (LFO) controlled by the music’s BPM rhythm to create a frequency
sweep Phaser sound. PARAM 1 regulates the FEEDBACK, and PARAM 2 controls the
DEPTH. With the TIME UP/DOWN buttons, you can adjust the oscillation cycle from 1:1 to
32:1.
FLANGER
This is a delay modulated by a low sine frequency oscillator (LFO) that is controlled by the
music’s BPM rhythm. This produces a highly dynamic swirling sound effect. PARAM 1
regulates the FEEDBACK, and PARAM 2 controls the DEPTH. With the TIME UP/DOWN
buttons, you can adjust the oscillation cycle from 1:1 to 32:1.
PITCH
This effect allows you to displace the pitch of an input signal without altering its duration. It
is usually used to change the key of the sound. PARAM 1 controls the PITCH by ±12 tones
in 100 steps.
TRANS
This is a volume transformation effect similar to the manipulation of a time-synchronized
fader.
PARAM 1 regulates the VOLUME, and PARAM 2 controls the DEPTH. With the TIME
UP/DOWN buttons, you can adjust the oscillation cycle from 1:4 to 32:1.
PAN
This is a panning effect, i.e. time-synchronized balance oscillation between the L and R
channels.
PARAM 1 regulates the PAN, and PARAM 2 controls the DEPTH. With the TIME
UP/DOWN buttons, you can adjust the oscillation cycle from 1:4 to 32:1.
