filter reduces the frequencies more gently than LPF2.
This can be very effective with acoustic-instrument-based
Tones, since nothing is done to weaken the power and
energy of the sound.
* This disables the Resonance setting.
Cutoff Freq (TVF Cutoff Frequency)
Range: 0–127
Specifies the frequency (cutoff frequency) at which the filter
will begin to affect the frequency characteristics of the
waveform.
With LPF/LPF2/LPF3 selected for the Filter Type parameter,
lower cutoff frequency settings reduce a Tone's upper
harmonics for a more rounded, warmer sound. Higher
settings make it sound brighter.
When Filter Type is BPF, the cutoff frequency setting
determines the range of frequencies within the Tone that will
be heard. It is useful for making distinctive sounds.
When Filter Type is HPF, higher settings of the cutoff
frequency decrease the level of the Tone's low frequencies,
preserving its brighter qualities.
When Filter Type is PKG, the cutoff frequency setting
determines the range of frequencies to be emphasized.
Resonance (TVF Resonance)
Range: 0–127
Increases the level of the cutoff frequency, adding character
to the sound. Excessively high settings can produce
oscillation, causing the sound to distort.

Resonance Velo (TVF Resonance
Velocity)
Sens (TVF Resonance Velocity Sens)
Range: -63– +63
Use this parameter when you want velocity to affect the
amount of Resonance. For higher settings, there will be a
greater difference between softly and strongly played notes.
HPF PKG
Chapter 4 Creating Patches
Negative (-) values invert the change.
Cutoff Keyfollow (TVF Cutoff
Keyfollow)
Range: -200– +200
Use this parameter if you want the cutoff frequency to
change according to the key that is pressed. At Middle C
(C4), the original Cutoff value is used. Positive (+) settings
cause the cutoff frequency to rise for notes higher than
Middle C, and negative (-) settings cause the cutoff frequency
to fall for notes higher than Middle C. Higher values will
cause greater change.
Cutoff Velo (TVF Cutoff Velocity)
Curv (TVF Cutoff Velocity Curve)
Range: FIXED/1–7
Selects one of seven curves that determine how keyboard
playing dynamics (velocity) influence the Tone's cutoff
frequency. The selected curve is displayed graphically to the
below of its value.
When V-Curve is set to "FIXED," the cutoff frequency
remains unchanged regardless of how hard or soft the keys
are played.
Sens (TVF Cutoff Velocity Sens)
Range: -63– +63
Sets the amount of change produced when the keyboard
touch is used to change the cutoff frequency. For higher
settings, there will be a greater difference between softly and
strongly played notes. Negative (-) values invert the change.
