Modulation and delay effects
The VT20+/VT40+/VT80+/VT120+ provides eleven types of modulation
effects, delays and other effects.
The SPEED parameter of modulation effects and the TIME parameter of delay
effects can be easily adjusted by pressing the TAP switch twice.
HINT: To set a precise speed or time that matches the tempo of a song,
press the TAP switch several times in rhythm with the song.
You can use the DEPTH knob to adjust most of the parameters. In addition,
you can hold down the TAP switch and turn the DEPTH knob to make more
detailed settings.
NOTE: To turn the modulation/delay effect off, rotate the DEPTH knob
all the way to the left.
