Roland XV-5080 Resonance Velo TVF Resonance Velocity, Cutoff Keyfollow TVF Cutoff, 141

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.

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	Chap
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.
