Chapter 5. Creating Patches
LPF2: Low Pass Filter 2. Although frequency components
above the Cutoff frequency (Cutoff parameter) 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 parameter) 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.
If you set LPF2 or LPF3, the setting for the Resonance
parameter will be ignored.
Cutoff (Cutoff Frequency) ★
Selects the frequency at which the filter begins to have an
effect on the waveform’s frequency components.
With LPF/LPF2/LPF3 selected for the 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 the Type parameter is BPF, the cutoff frequency
setting determines the range of frequencies within the Tone
that will be heard. This can be useful when creating
distinctive sounds.
When the Type parameter is HPF, higher settings of the
cutoff frequency decrease the level of the Tone’s low
frequencies, preserving its brighter qualities.
With PKG selected, the harmonics to be emphasized will
vary depending on Cutoff Frequency setting.
To edit the overall Patch while preserving the relative
differences in the Cutoff Frequency values set for each
Tone, set the Cut parameter (PATCH/COMMON/
PATCH MODIFY) (p. 71).
Resonance ★
Emphasizes the portion of the sound in the region of the cutoff
frequency, adding character to the sound. Excessively high
settings can produce oscillation, causing the sound to distort.
To edit the overall Patch while preserving the relative
differences in the Resonance values set for each Tone, set
the Res parameter (PATCH/COMMON/PATCH
MODIFY) (p. 71).

Keyfollow (Cutoff Frequency Keyfollow)
Use this parameter if you want the cutoff frequency to
change according to the key that is pressed. Relative to the
cutoff frequency at the C4 key (center C), positive (+) settings
will cause the cutoff frequency to rise for notes higher than
C4, and negative (-) settings will cause the cutoff frequency
to fall for notes higher than C4. Higher settings produce
more change.
