LFO1(2) KEY SYNC

OFF, ON

Sets whether you want the LFO cycle to start in sync with the

(LFO Key Sync)

 

timing of a key press (ON) or not (OFF).

LFO1(2) PITCH DEPTH

-63–+63

Adjusts how much the LFO affects the Tone’s pitch.

 

 

 

LFO1(2) TVF DEPTH

-63–+63

Adjusts how much the LFO affects the Tone’s TVF cutoff fre-

 

 

quency.

LFO1(2) TVA DEPTH

-63–+63

Adjusts how much the LFO affects the Tone’s TVA Level.

 

 

 

LFO1(2) PAN DEPTH

-63–+63

Adjusts how much the LFO affects the Tone’s TVA Pan.

 

 

 

*Noise may result from making the LFO PAN DEPTH too deep. To prevent noise, you can either lower the value for the PAN DEPTH, or lower the LFO Rate.

PATCH TVF (Changing the Brightness with a Filter)

The settings for the TVF (Time Variant Filter) allow you to change a Tone’s timbral content by altering its brightness or thickness.

Description

 

 

 

FILTER TYPE

OFF, LPF, BPF,

Selects a filter type. A filter typically reduces, or attenuates, a specific frequency

 

HPF, PKG,

range within a Tone in order to accentuate its other frequencies.

 

LPF2, LPF3

OFF: No filter is used.

 

 

LPF: A Low Pass Filter reduces the volume of frequencies above the cutoff fre-

 

 

quency in order to un-brighten the sound. This is the most common filter used

 

 

in synthesizers.

 

 

BPF: A Band Pass Filter reduces the volume of frequencies below and above the

 

 

cutoff frequency range. This is most effective when creating sounds with a

 

 

strong character since it can accentuate a desired range of frequencies anywhere

 

 

in the sound.

 

 

HPF: A High Pass Filter reduces the volume of the frequencies below the cutoff

 

 

frequency. This is suitable for creating percussive sounds by rolling of their low-

 

 

er frequencies, thus emphasizing their higher ones.

 

 

PKG: A Peaking Filter emphasizes frequencies around the cutoff frequency by

 

 

raising their level. You can use this to create wah-wah effects by employing an

 

 

LFO to change the cutoff frequency cyclically.

 

 

LPF2: Low Pass Filter 2. This reduces the volume of all frequencies above the

 

 

cutoff frequency. This differs from LPF in that you can control the amount of the

 

 

reduction using the TVF ENVELOPE settings while still maintaining a fixed cut-

 

 

off frequency. 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.

 

 

LPF3: Low Pass Filter 3 reduces the volume of frequencies above the cutoff fre-

 

 

quency. While similar to LPF2, it reduces the frequencies more gently than LPF2.

 

 

This can also be effective with acoustic-instrument-based Tones.

 

 

* This disables the Resonance setting.

 

 

 

CUTOFF

0–127

Adjusts the frequency at which the filter begins to have an effect on the waveform’s

(Cutoff Frequency)

 

frequency components. With LPF/LPF2/LPF3 selected for the Filter Type param-

 

 

eter, 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. This can be useful when creating sounds that need to stand

 

 

out. 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.
