Parameter Value Explanation
Selects the type of filter. A filter modifies the
brightness or thickness of the sound by cutting a
specific frequency range:
• "OFF": No filter used
• "LPF": Low Pass Filter. This reduces the volume
of all frequencies above the cutoff frequency
(Cutoff Freq) in order to round off, or un-brighten
the sound. This is the most common filter used in
synthesizers.
• "BPF": Band Pass Filter. This leaves only the
frequencies in the region of the cutoff frequency
(Cutoff Freq), and cuts the rest. This can be useful
when creating distinctive sounds.
• "HPF": High Pass Filter. This cuts the frequencies
in the region below the cutoff frequency (Cutoff
Freq). This is suitable for creating percussive
sounds emphasizing their higher tones.

• "PKG": Peaking Filter. This emphasizes the

frequencies in the region of the cutoff frequency
LPF3,
(Cutoff Freq). You can use this to create wah-wah
effects by employing an LFO to change the cutoff
frequency cyclically.
• "LPF2": Low Pass Filter 2. Although frequency
components above the Cutoff frequency (Cutoff
Freq) are cut, the sensitivity of this filter is half
that of the LPF. This makes it a comparatively
warmer low pass filter. This filter is good for use
with simulated instrument sounds such as the
acoustic piano.
• "LPF3": Low Pass Filter 3. Although frequency
components above the Cutoff frequency (Cutoff
Freq) are cut, the sensitivity of this filter changes
according to the Cutoff frequency. While this
filter is also good for use with simulated acoustic
instrument sounds, the nuance it exhibits differs
from that of the LPF2, even with the same TVF
Envelope settings
Selects the point at which the filter begins to have
TVF Cutoff 0~127
an effect on the waveform's frequency components.
Emphasizes the portion of the sound in the region
of the cutoff frequency, adding character to the
TVF Resonance 0~127
sound. Excessively high settings can produce
oscillation, causing the sound to distort.
Specifies the depth of the TVF envelope. Higher
settings will cause the TVF envelope to produce
TVF Env Depth -63~0~+63
greater change. Negative (-) settings will invert the
shape of the envelope.
Specify the TVF envelope times (Time A–Time R).
Higher settings will lengthen the time until the next

Sets the volume of the tone. This setting is useful
TVA Level 0~127 primarily for adjusting the volume balance between
tones.
Specify the TVA envelope levels (Level A–Level R).

These settings specify how the volume will change
at each point, relative to the standard volume (the
