Creating a Patch

Cutoff Frequency

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.

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).

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.

Value:

0–127

To edit the overall patch while preserving the relative

differences in the Resonance values set for each tone,

set the Resonance Offset parameter (p. 98).

Cutoff 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. Larger settings will produce

greater change.

Value:

-200, -190, -180, -170, -160, -150, -140, -130, -120,

-110, -100, -90, -80, -70, -60, -50, -40, -30, -20, -10,

0, +10, +20, +30, +40, +50, +60, +70, +80, +90,

+100, +110, +120, +130, +140, +150, +160, +170,

+180, +190, +200

Cutoff V-Curve
(Cutoff Frequency Velocity Curve)

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.

Value:

FIXED,
