Filter/Dynamic

If Sweep Mode is set to LFO, the sound will change cycli- cally from “a” to “i,” “u,” “i,” then “a.”

h: Formant Shift

This parameter adjusts the frequency level to which the effect is applied. If you wish to apply the effect to a higher-range sound, set this parameter to a higher value; to apply the effect to a lower-range sound, set this to a lower value.

h: Resonance

This parameter sets the intensity of resonance for the voice pattern. A larger value will add more character to the sound.

014: Decimator

(Stereo Decimator)

This effect creates a rough sound like a cheap sampler by low- ering the sampling frequency and data bit length. You can also simulate noise unique to a sampler (aliasing).

a: Pre LPF

If a sampler with a very low sampling frequency receives very high-pitched sound that could not be heard during playback, it could generate pitch noise that is unrelated to the original sound. Set “Pre LPF” to ON to prevent this noise from being generated.

If you set the “Sampling Freq” to about 3kHz and set “Pre LPF” to OFF, you can create a sound like a ring modulator. e: Resolution, f: Output Level

If you set a smaller value for the “Resolution” parameter, the sound may be distorted. The volume level may also be changed. Use “Output Level” to adjust the level.
