Using the XV-2020 Effects
9: COMPRESSOR
Flattens out high levels and boosts low levels, smoothing out
fluctuations in volume.
fig.02-009m
10: LIMITER
Compresses signals that exceed a specified volume level, preventing
distortion from occurring.
fig.02-010m
11: HEXA-CHORUS
Uses a six-phase chorus (six layers of chorused sound) to give
richness and spaciousness to the sound.
fig.02-011m
12: TREMOLO CHORUS
This is a chorus effect with added Tremolo (cyclic modulation of
volume).
fig.02-012m
