Creating a Patch
Cutoff Frequency ★
110
Selects the frequency at which the filter begins to have an
effect on the waveform’s frequency components.
Value: 0–127
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.
If “BPF” is selected, harmonic components will change
depending on the TVF Cutoff Frequency setting. This can be
useful when creating distinctive sounds.
With “HPF” selected, higher Cutoff Frequency settings will
reduce lower harmonics to emphasize just the brighter
components of the sound.
With “PKG” selected, the harmonics to be emphasized will
vary depending on Cutoff Frequency setting.
Resonance ★
fig.06-034.e
To edit the overall patch while preserving the relative
differences in the Cutoff Frequency values set for each
tone, set the Cutoff Offset parameter (p. 98).
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.

Cutoff Keyfollow
fig.06-035.e
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. Larger settings will produce
greater change.

Selects one of the following seven curves that determine
how keyboard playing dynamics (velocity) influence the
cutoff frequency. Set this to “FIXED” if you don’t want the
Cutoff frequency to be affected by the keyboard velocity.
