R
Pre Dly (Pre Delay Time)
Adjusts the time delay from when the direct sound begins
until the processed sound is heard.
Rate
Adjusts the rate of modulation.
Depth
Adjusts the depth of modulation.
+Feedback (Feedback Level)
Adjusts the amount (%) of the processed sound that is
returned (fed back) into the input. Negative (-) settings will
invert the phase.
Phase
Adjusts the spatial spread of the sound.
#Step Rate
Adjusts the rate (period) of pitch change.
Balance (Effect Balance)
Adjusts the volume balance between the direct and the
processed sound.
"D" and "E" stand for "direct sound" and "effect sound"
respectively.
Low Gain
Adjusts the gain of the low frequency range.
Hi Gain (High Gain)
Adjusts the gain of the high frequency range.
Level (Output Level)
Adjusts the output level.

12: Tremolo

Tremolo cyclically modulates the volume to add tremolo
effect to the sound.

Mod Wave (Modulation Wave)
Tri/Sqr/Sin/Saw1/Saw2 [1 (40 03 03)]
Selects the type of modulation.
Tri: The sound will be modulated like a triangle
wave.
Sqr: The sound will be modulated like a square
wave.
Sin: The sound will be modulated like a sine
wave.
Saw1,2: The sound will be modulated like a
sawtooth wave. The teeth in Saw1 and
Saw2 point at opposite directions.
