5. Pattern mode

Ring Mod. (ring modulation)

This effect applies modulation to the sound in order to cre- ate metallic resonances or unusual sound effects.

Edit 1 _ Frequency 0...127

Specifies the frequency of the modulation that will be ap- plied. The frequency will rise as the knob is rotated toward the right.

Edit 2 _ Balance 0...127

Specifies the balance of the effect sound and direct sound. As the knob is rotated toward the right, the effect sound will increase and the direct sound will decrease.

Pitch Shifter
This effect shifts the pitch.
Edit 1 _ Pitch	0...127

Specifies the amount of pitch shift. When the knob is in the center position, the output pitch will be the same as the in- put pitch. As the knob is rotated toward the left the pitch will become lower, and as the knob is rotated toward the right the pitch will become higher. The available range of pitch shift is +/-2 octaves, and will change as shown below.

Knob value	Pitch	Example pitch (input note C3)
127	2 octaves		C5
105, 107...125	◊		C 4, D4...B4
103	1 octave		C4
73, 76...97, 100	◊		D3, D 3...A 3, B3
70	semitone up		C 3
64 (center)	0		C3
57	semitone down		B2
27, 30...51, 54	◊		C 2, D2...A2, A 2
24	–1 octave		C2
2, 4...20, 22	◊		C 1, D1...A 1, B1
0	–2 octaves		C1
Edit 2 _ Dry level			0...127

This adds the original sound to the pitch-shifted sound. As the knob is rotated toward the right, increasing amounts of the original sound will be added to the effect sound.

Compressor

A compressor boosts low level sounds and reduces high level sounds in order to minimize differences in volume and make the sound more consistent.

Edit 1 _ Sensitivity 0...127

Specifies the sensitivity of the compressor. When the knob is in the far left position, there will be no effect. As the knob is rotated toward the right, the effect will apply more strongly.

Edit 2 _ Attack 0...127

Specifies the attack speed until the compressor begins to take effect. The attack will become slower as the knob is rotated toward the right.

Decimator

This effect lowers the sampling frequency and the number of sampling bits, producing a grainy sound characteristic of cheap samplers.

Edit 1 _ Sampling frequency 0...127

Rotating the knob toward the right produces a more lo-fi sound, and rotating it toward the left produces a more hi-fi sound.

Edit 2 _ Number of sampling bits 0...127

Rotating the knob toward the right will produce a sound typical of fewer bits (lo-fi), and rotating it toward the left will produce a sound typical of more bits (hi-fi).

If the input volume is extremely low, there may be no output. If there is a high noise level during silent times, noise may be generated.

Isolator

This effect cuts the sound of a specific frequency. You can use this to cut just the vocal range, or just the bass range, etc. Edit 2 (Mid Control) will take priority.

Edit 1 _ Low / High Control 0...127

This controls the low or high range. Rotating the knob to- ward the left will cut the high range, and rotating it toward the right will cut the low range.

Edit 2 _ Mid control 0...127

This controls the mid range. Rotating the knob toward the left will cut the mid range, and rotating it toward the right will retain only the mid range.

Reso. Filt. (resonance filter)

This is a low pass filter with resonance. It cuts the over- tones that are above the cutoff frequency, producing a milder tone.

Edit 1 _ Cutoff Frequency 0...127

Adjusts the cutoff frequency of the low pass filter. The cut- off frequency will rise as the knob is rotated toward the right.

Edit 2 _ Resonance 0...127

This emphasizes the sound in the region of the cutoff fre- quency, adding a distinctive character to the sound.

Depending on the cutoff frequency or input sound, high

resonance settings may cause the sound to distort.

Wah

This is a wah that uses an LFO to control the cutoff frequency.

Edit 1 _ LFO Rate 0...127

Adjusts the speed of the LFO that controls the cutoff fre- quency. Rotating the knob toward the right will increase the LFO speed.

Edit 2 _ Cutoff Frequency 0...127

Adjusts the cutoff frequency. Rotating the knob toward the right will raise the cutoff frequency.

5. Pattern mode

Distortion

By boosting the volume appropriately, this effect causes the sound to distort and produces a rich overtone structure.

Edit 1 _ Gain 0...127

Specifies the degree of distortion. The sound will be dis- torted more greatly as the knob is rotated toward the right.

Edit 2 _ Level 0...127

Adjusts the output level. The output level will increase as the knob is rotated toward the right.
