MFX types and parameters<br />

16. St. Flanger<br />

This is a stereo flanger. It produces a metallic resonance that<br />

rises and falls like a jet airplane taking off or landing.<br />

● Filter Type (OFF, LPF, HPF)—Type of filter. OFF: no filter is used.<br />

LPF: cuts the frequency range above the Cutoff value. HPF: cuts<br />

the frequency range below the Cutoff value.<br />

● Cutoff Frequency (200~8000Hz)—Basic frequency of the filter.<br />

● Flanger Pre Delay (0.0~100.0ms)—Adjusts the delay time from<br />

when the direct sound begins until the flanger sound is heard.<br />

● Flanger Rate (0.05~10.0Hz)—Frequency, i.e. modulation speed.<br />

● Flanger Depth (0~127)—Modulation intensity.<br />

● Flanger Phase (0~180 deg)—Spatial spread of the sound.<br />

● Flanger Feedback (–98%~0~98%)—Adjusts the proportion of<br />

the flanger sound that is fed back into the effect. Negative (–)<br />

settings will invert the phase.<br />

● EQ Low Gain (–15dB~0~15dB)—Gain of the low range.<br />

● EQ High Gain (–15dB~0~15dB)—Gain of the high range.<br />

● Balance (D100:0W, D50:50W, D0:100W)—Volume balance<br />

between the direct (D) and the effect sound (W).<br />

● Level (0~127)—Output level.<br />

17. Step Flanger<br />

A Step Flanger is a flanger effect with clearly noticeable steps<br />

rather than continuous pitch changes.<br />

● Flanger Pre Delay (0.0~100.0ms)—Adjusts the delay time from<br />

when the direct sound begins until the flanger sound is heard.<br />

between the direct (D) and the effect sound (W).<br />

● Level (0~127)—Output level.<br />

18. St. Delay<br />

Delay is an effect that allows you repeat the input signal, thus<br />

creating echoes (repetition).<br />

● Delay F<strong>BK</strong> Mode (Normal, Cross)—Select the way in which delay<br />

sound is fed back into the effect. NORMAL: The left delay sound<br />

will be fed back into the left delay and the right delay sound<br />

into the right delay. CROSS: The left delay sound will be fed<br />

back into the right delay and the right delay sound into the left<br />

delay.<br />

sound until when the left delay sound is heard.<br />

● Delay Right (0.0~500.0ms)—Adjust the time from the direct<br />

sound until when the right delay sound is heard.<br />

● F<strong>BK</strong> Phase Left (Normal, Invert)—Select the phase of the left<br />

delay sound. NORMAL: Phase is not changed. INVERT: Phase is<br />

inverted.<br />

● F<strong>BK</strong> Phase Right (Normal, Invert)—Select the phase of the right<br />

delay sound. NORMAL: Phase is not changed. INVERT: Phase is<br />

inverted.<br />

● Delay Feedback (–98%~0~98%)—Adjusts the amount of the<br />

delay sound that’s fed back into the effect. Negative (–) settings<br />

invert the phase.<br />

● Delay HF Damp (200~8000Hz, Bypass)—Adjusts the frequency<br />

above which sound fed back to the effect is filtered out. If you<br />

don’t want to filter out any high frequencies, set this parameter<br />

to BYPASS.<br />

● EQ Low Gain (–15dB~0~15dB)—Gain of the low range.<br />

● EQ High Gain (–15dB~0~15dB)—Gain of the high range.<br />

● Balance (D100:0W, D50:50W, D0:100W)—Volume balance<br />

between the direct (D) and the effect sound (W).<br />

● Level (0~127)—Output level.<br />

19. Mod. Delay<br />

This effect adds modulation to the delayed sound, producing<br />

an effect similar to a Flanger.<br />

● Delay F<strong>BK</strong> Mode (Normal, Cross)—Select the way in which delay<br />

sound is fed back into the effect. NORMAL: The left delay sound<br />

will be fed back into the left delay and the right delay sound<br />

into the right delay. CROSS: The left delay sound will be fed<br />

back into the right delay and the right delay sound into the left<br />

delay.<br />

speed.<br />
