EFFECTS
Use the FX SELECT switch to choose the desired effect. Press the EFFECTS button to toggle the effect on and off. You can
use the WET/DRY fader to adjust the effect presence in the mix. Most effects can by synched to a ratio of the BPM counter by
holding down the PARAMETER knob while turning it, or controlled manually by turning the PARAMETER knob without holding
it down.
There are six effects available:
FILTER: An isolation (band pass) filter that lets you play only a specific frequency of the music. Rotation
of the PARAMETER knob moves the filter frequency. If you press down on the PARAMETER
knob while turning it performs a coarse adjustment to the frequency. If you just turn the
PARAMETER knob without holding it down it will perform a fine adjustment of the filter
frequency.
ECHO: Creates a reverb effect. The rate can be adjusted with the PARAMETER knob. Holding down
the PARAMETER knob while turning will allow you to synch the effect to a ratio of the BPM
counter.
CHOP: Simulates turning a mute button on and off in time with the music. The speed of the effect is
controlled by turning the PARAMETER knob and can also be synched to a ratio of the BPM
counter by pressing down on the PARAMETER knob while turning it.
PAN: Alternates playing the right then left speaker channel based on either the tempo of the BPM
counter or the speed selected manually. To set the rate, turn the PARAMETER knob. You can
synch the speed to a ratio of the BPM counter by pressing down on the PARAMETER knob
while turning it.
PHASER: Sweeping phase shifter effect. It is similar to the flange effect, except that the flange effect has a
more pronounced harmonic sound. A phase shifter is enharmonic, and has a more "swooshing"
sound. The speed of the effect is controlled by turning the PARAMETER knob and can also be
synched to a ratio of the BPM counter by pressing down on the knob while turning it.
FLANGER: Sweeping effect with a more pronounced harmonic sound than the phaser, reminiscent of a jet
engine passing overhead. The speed of the effect is controlled turning by the PARAMETER
knob and can also be synched to a ratio of the BPM counter by pressing down on the knob
while turning it.
Wet/Dry Fader
In addition to the PARAMETER knob there is also a WET/DRY fader that allows you to adjust the balance between effected
and unaffected audio. As you move the fader from DRY to WET you will more and more of the effected sound.
