62
A phaser that continues raising/lowering the frequency at which the
sound is modulated.
fig.MFX-14
This is an effect that applies amplitude modulation (AM) to the input
signal, producing bell-like sounds. You can also change the
modulation frequency in response to changes in the volume of the
sound sent into the effect.
fig.MFX-15
This is a ring modulator that uses a 16-step sequence to vary the
frequency at which modulation is applied.
fig.MFX-16
Cyclically modulates the volume to add tremolo effect to the sound.
