Creating a Rhythm SetModifying the Brightness of aSound with a Filter (TVF/TVF Env)If you set “LPF2” or “LPF3,” the setting for the Resonanceparameter will be ignored.fig.07-012_50Cutoff Frequency1TVFFor details on these settings, refer to “How to make RhythmSet settings” (p. 83).Filter Type 3Selects the type of filter. A filter cuts or boosts a specific frequencyregion to change a sound's brightness, thickness, or other qualities.ValueOFF: No filter is used.LPF: Low Pass Filter. This reduces the volume of allfrequencies above the cutoff frequency (Cutoff Freq)in order to round off, or un-brighten the sound. Thisis the most common filter used in synthesizers.BPF: Band Pass Filter. This leaves only the frequencies inthe region of the cutoff frequency (CutoffFrequency), and cuts the rest. This can be usefulwhen creating distinctive sounds.HPF: High Pass Filter. This cuts the frequencies in theregion below the cutoff frequency (CutoffFrequency). This is suitable for creating percussivesounds emphasizing their higher ones.PKG: Peaking Filter. This emphasizes the frequencies inthe region of the cutoff frequency (CutoffFrequency). You can use this to create wah-waheffects by employing an LFO to change the cutofffrequency cyclically.LPF2: Low Pass Filter 2. Although frequency componentsabove the Cutoff frequency (Cutoff Frequency) arecut, the sensitivity of this filter is half that of the LPF.This makes it a comparatively warmer low passfilter. This filter is good for use with simulatedinstrument sounds such as the acoustic piano.LPF3: Low Pass Filter 3. Although frequency componentsabove the Cutoff frequency (Cutoff Frequency) arecut, the sensitivity of this filter changes according tothe Cutoff frequency. While this filter is also goodfor 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 frequency at which the filter begins to have an effect onthe waveform’s frequency components.Value: 0–127With “LPF/LPF2/LPF3” selected for the Filter Type parameter,lower cutoff frequency settings reduce a tone’s upper harmonics fora more rounded, warmer sound. Higher settings make it soundbrighter.If “BPF” is selected, harmonic components will change dependingon the TVF Cutoff Frequency setting. This can be useful whencreating distinctive sounds.With “HPF” selected, higher Cutoff Frequency settings will reducelower harmonics to emphasize just the brighter components of thesound.With “PKG” selected, the harmonics to be emphasized will varydepending on Cutoff Frequency setting.ResonanceEmphasizes the portion of the sound in the region of the cutofffrequency, adding character to the sound. Excessively high settingscan produce oscillation, causing the sound to distort.Value: 0–127fig.06-034.eCutoff V-Curve (Cutoff Frequency VelocityCurve)Selects one of the following seven curves that determine howkeyboard playing dynamics (velocity) influence the cutoff frequency.Set this to “FIXED” if you don't want the Cutoff frequency to beaffected by the keyboard velocity.Value: FIXED, 1–7fig.06-0362LPF BPF HPF PKGLevelHighparameter valueLowFrequencyCutoff frequency1 2 3 4 5 6 792
