3. CUTOFF FREQUENCY

Range: 0 … 127

Sets the basic frequency around which the wah filter sweep will occur.

4. RESONANCE

Range: 1 … 12

Creates a resonant peak at the frequency determined by the CUTOFF FREQUENCY parameter, above.
The higher the value the higher the peak, and the more the sound at that frequency is emphasized.

In the DelayLCR effect, independent delays are provided for the left and right channels, plus a center

delay. The DelayL,R variation provides independently programmable delays for the left and right chan-
nels.

1. L CH DELAY
2. R CH DELAY
3. C CH DELAY

Range: 0.1 … 715 ms

Set the delay time between the direct sound and the first repeat. Independent parameters are provided for
the left (“L CH”), center (“C CH”), and right (“R CH”) channels. Only the L CH DELAY and R CH DELAY
time parameters are available for the DelayL,R effect.

4. FEEDBACK DELAY (DelayLCR)
3. FEEDBACK DELAY 1 & 4.FEEDBACK DELAY2 (DelayL,R)

Range: 0.1 … 715 ms

Sets the delay time between repeats. The higher the value the longer the delay. In the DelayL,R effect
independent feedback delay parameters are provided for the left and right channels.

5. FEEDBACK LEVELRange: –63 … 0 … +63

Determines the amount of effect-sound feedback returned to the input of the delay stage. Higher values
produce a greater number of repeats.

Although similar to the DelayL,R effect, Echo features independent feedback level parameters for the

left and right channels, plus a “high damp” parameter that simulates the high-frequency damping charac-
teristics of most natural acoustic environments.

1. L CH DELAY
3. R CH DELAY

Range: 0.1 … 715 ms

Set the delay time between the direct sound and the first repeat. Independent parameters are provided for
the left (“L CH”) and right (“R CH”) channels.

2. L CH FB LEVEL
4. R CH FB LEVEL

Range: –63 … 0 … +63

Determine the amount of effect-sound feedback returned to the input of the corresponding delay stage
channel: L CH FB LEVEL for the left channel and R CH FB LEVEL for the right channel. Higher values
produce a greater number of repeats.

5. HIGH DAMP

Range: 0.1 … 1

Produces a natural decay in the high-frequency components of subsequent repeats. The lower the value
the faster and more pronounced the drop-off in high-frequencies.

38. DelayLCR

39. DelayL,R

40. Echo
