43. Low Boost
Boosts the volume of the lower range, creating powerful
lows.
● Boost Frequency (50~125 [Hz])—Center frequency at
which the lower range will be boosted.
● Boost Gain (0~12 [dB])—Amount by which the lower
range will be boosted.
● Boost Width (Wide, Mid, Narrow)—Width of the lower
range that will be boosted.
● EQ Low Gain (-15dB~0~15dB)—Gain of the low fre-
quency range.
● EQ High Gain (-15dB~0~15dB)—Gain of the high fre-
quency range.
44. Super Filter
This is a filter with an extremely sharp slope. The cutoff fre-
quency can be varied cyclically.
● Filter Type (LPF, BPF, HPF, NOTCH)—Filter type. Fre-
quency range that will pass through each filter. LPF: fre-
quencies below the cutoff. BPF: frequencies in the region
of the cutoff. HPF: frequencies above the cutoff. NOTCH:
frequencies other than the region of the cutoff.
● Filter Slope (–12, –24, –36 [dB])—Amount of attenuation
per octave: –36dB: extremely steep, –24dB: steep, –12dB:
gentle.
● Filter Cutoff (0~127)—Cutoff frequency of the filter.
Increasing this value will raise the cutoff frequency.
● Filter Resonance (0~127)—Filter resonance level. Increas-
ing this value will emphasize the region near the cutoff
frequency.
● Filter Gain (0~12 [dB])—Amount of boost for the filter
output.
● Modulation Sw (Off, On)—On/off switch for cyclic
change.
● Modulation Wave (TRI, SQR, SIN, SAW1, SAW2)—How
the cutoff frequency will be modulated: TRI: triangle wave,
SQR: square wave, SIN: sine wave, SAW1: sawtooth wave
(upward), SWA2: sawtooth wave (downward)
● Rate [sync] (Hz, Note)—Use this parameter to specify
whether (“Note”) or not (“Hz”) the modulation rate should
be synchronized to the Arranger or Recorder tempo.
Depending on your choice, the setting range of the follow-
ing parameter refers to a speed (Hz) or a note value.
● Rate [Hz] (0.05~10.00Hz)—Rate of modulation.
● Rate [note] (musical notes)—Rate parameters can be set
as a note-value of a tempo if you set the “Sync” parameter
above to “Note”. Specify the value of the desired note.
● Depth (0~127)—Depth of modulation.
● Attack (0~127)—Speed at which the cutoff frequency will
change This is effective if Modulation Wave is SQR, SAW1,
or SAW2.
45. Step Filter
This is a filter whose cutoff frequency can be modulated in
steps. You can specify the pattern by which the cutoff fre-
quency will change.
● Step 1~16 (0~127)—Cutoff frequency at each step
● Rate [sync] (Hz, Note)—Use this parameter to specify
whether (“Note”) or not (“Hz”) the rate should be synchro-
nized to the Arranger or Recorder tempo. Depending on
your choice, the setting range of the following parameter
refers to a speed (Hz) or a note value.
● Attack (0~127)—Speed at which the cutoff frequency
changes between steps.
● Filter Type (LPF, BPF, HPF, NOTCH)—Filter type. Fre-
● Filter Slope (–12, –24, –36 [dB])—Amount of attenuation
per octave: –36dB: extremely steep, –24dB: steep, –12dB:
gentle.
● Filter Resonance (0~127)—Filter resonance level. Increas-
ing this value will emphasize the region near the cutoff
frequency.
● Filter Gain (0~12 [dB])—Amount of boost for the filter
46. Humanizer
Adds a vowel character to the sound, making it similar to a
human voice.
● Drive Sw (OFF,ON)—Turns Drive on/off.
● Drive (0~127)—Degree of distortion. Also changes the vol-
● Vowel 1 (a, e, i, o, u)
● Vowel 2 (a, e, i, o, u)—Selects the vowel.
● Rate [sync] (Hz, Note)—Use this parameter to specify
● Rate [Hz] (0.05~10.00Hz)—Frequency at which the two
vowels switch.
● Rate [note] (musical notes)—Rate parameters can be set
● Depth (0~127)—Effect depth.
● Input Sync Sw (Off, On)—Determines whether the LFO for
switching the vowels is reset by the input signal (ON) or
not (OFF).
● Input Sync Threshold (0~127)—Volume level at which
reset is applied.
● Manual (0~100)—Point at which Vowel 1/2 switch. 49 or
less: Vowel 1 will have a longer duration. 50: Vowel 1 and 2
will be of equal duration. 50 or more: Vowel 2 will have a
longer duration.
● EQ EQ Low Gain (–15dB~0~15dB)—Gain of the low fre-
