Panel Descriptions
6 PITCH
Here you can create time-varying change (envelope) for pitch.
Controller Value Explanation
[ENV] knob -128–0–+127
If this knob is turned toward the right, the pitch initially becomes higher and then
returns to the pitch of the key you pressed.
If this knob is turned toward the left, the pitch initially becomes lower and then
returns to the pitch of the key you pressed.
[A] slider
0–255
These sliders operate similarly to the [A] [D] sliders of the
8
AMP section (they aect
the pitch rather than the volume).
[D] slider
7 FILTER
These settings determine the brightness and thickness of the sound. Here you can also specify the time-varying change (envelope) for the lter.
Controller Value Explanation
[VARIATION] knob
(only for MODEL:
SYSTEM-8)
Selects the variation of the FILTER section.
LPF/HPF (Variation 1) Low pass lter (LPF), High pass lter (HPF)
SBF (Variation 2) Side band lter (SBF)
(Variation 3) This is a SYSTEM-1 type low pass lter (LPF).
[CUTOFF] knob 0–255
Species the cuto frequency of the lter.
This knob is a GRF (GRIFFER) knob which allows high-precision adjustments.
Filter type knob
(only for MODEL:
SYSTEM-8)
Selects the slope of the lter.
(Variation 1)
LPF-24dB, LPF-18dB,
LPF-12dB, HPF-12dB,
HPF-18dB, HPF-24dB

(Variation 2)
SBF1–SBF6
Side band lter (SBF)
You can use the [CUTOFF] knob to adjust the band interval.
You can also use the lter type knob to select the range of the band interval.
SBF1–3: Low range, Mid range, High range with original sound
SBF4–6: High range, Mid range, Low range without original sound
You can use the resonance knob to adjust the band width.
(Variation 3)
LPF-24dB, LPF-18dB,
LPF-12dB
This is a SYSTEM-1 type low pass lter (LPF)
Although the knob moves through six steps, this setting has three values. Even if you
move the knob to the fourth or subsequent step, the value is LPF-12 dB.
[RESO] knob 0–255
Resonance boosts the sound in the region of the lter’s cuto frequency.
Higher settings produce stronger emphasis, creating a distinctively “synthesizer-
like” sound.
[ENV] knob -128–0–+127
This knob species the depth and direction of the cuto frequency change produced
by the [A], [D], [S], and [R] sliders.
If the knob is turned toward the right, the cuto frequency moves in the upward
direction.
If the knob is turned toward the left, the cuto frequency moves in the downward
direction.
[KEY] knob -128–0–+127
Allows the lter cuto frequency to vary according to the key that you play.
If the knob is turned toward the right, the cuto frequency becomes higher as you
play higher notes.
If the knob is turned toward the left, the cuto frequency becomes lower as you play
lower notes.
[VELOCITY SENS]
knob
0–255
Adjusts the sensitivity by which the key velocity (playing dynamics) varies the depth
of the lter envelope.
[HPF CUTOFF] knob 0–255
Species the cuto frequency of the high-pass lter. Frequency components below
the cuto frequency are cut.
