Chapter 2. Using Effects
Type
20. VOICE TRANS.
Transforms a human voice into
various other voices.
21. C.CANCELER
Cancels the vocal or other sound
localized at the center of the
soundfield.
22. SUBSONIC
Adds a low-frequency sine wave
according to the volume that is
being input to the effect. (*4)
23. BPM LOOPER ★
Loops the input sound at a rapid
rate.
24. DJFX LOOPER ★
This effect is essentially BPM
LOOPER where TIMING is re-
placed by SPEED. You can
change the playback direction
and playback speed of the input
sound, creating an effect as
though you were manipulating a
turntable.
: This indicates an effect that will be limited if Effect Limit mode (p. 19) is on.
The ★ symbol in the CTRL 1–3 columns indicates the parameters whose depth will be limited.
*2: If "17. SLICER" is selected as the MFX, turning the CTRL 1 knob will select from the following TIMING PTN (timing patterns).
P01
P02
P03
P04
P05
P06
P07
P08
*3: The TIMING PTN cycle will synchronize to the tempo of the longest sample to which the effect is applied.
However, if a pattern is playing, the TIMING PTN cycle will synchronize to the pattern tempo.
You can use RATE to adjust the rate as follows.
RATE minimum (CTRL 2 knob turned fully counterclockwise): One cycle of TIMING PTN is equivalent to one measure.
RATE maximum (CTRL 2 knob turned fully clockwise): One cycle of TIMING PTN is equivalent to an eighth note.
You can turn the CTRL 2 knob to select rates of one measure, 1/2 measure, 1/4 measure, or 1/8 measure.
*4: Turn the CTRL 3 balance to the 12 o'clock position, turn the CTRL 1 pitch all the way to the right, and adjust the CTRL 2 threshold so that the
sine wave plays appropriately for the input source. When you've finished setting the threshold, adjust the pitch and balance.
This is a useful way to supplement a kick drum sound.
*5: The TIMING cycle will synchronize to the tempo of the longest sample to which the effect is applied.
However, if a pattern is playing, the TIMING cycle will synchronize to the pattern tempo.

CTRL 1 (display)
FORMANT (FrM)
Adjusts the basic character (for-
mant) of the voice.
L-R BALANCE (L-r)
Find the point at which the un-
wanted sound is cancelled most
effectively.
PITCH (Pit)
Adjusts the frequency of the sine
wave.
LENGTH (LEn) ★
Specifies the length of the loop.
LENGTH (LEn) ★
Specifies the length of the loop.
CTRL 2 (display)
EFFECT LEVEL (EFF)
Adjusts the volume of the effect
sound.
LOW BOOST (Lo)
Boosts the low-frequency sound
localized at the center of the
soundfield, such as the bass.
THRESHOLD (tHr)
Adjusts the volume level at
which the sine wave begins to
sound.
TIMING (oFF, 1–8)
Specifies the timing (8th note
units) at which the looped sound
will play automatically within
the measure. (*5)
* Set this to "oFF" if you don't
want the loop to play automati-
cally.
SPEED (-1.0–1.0)
Adjusts the playback direction
and speed. Turning the knob left
of the 12 o'clock position will
play the sound in reverse, and
turning it right of the 12 o'clock
position will play the sound for-
ward. Playback will stop at the 12
o'clock position.

DIRECT LEVEL (dir)

sound.

Boosts the high-frequency
sound.
BALANCE (bAL)
Adjusts the volume balance of
the direct sound and effect
sound.
LOOP SW (oFF, on)
If you turn this on while playing
sound, the sound at that moment
will be looped. Turn this off to
defeat looping.
LOOP SW (oFF, on)
If you turn this on while playing
sound, the sound at that moment
will be looped. Turn this off to
defeat looping.
