031: Black Chorus

This models a Danish‐made stereo chorus + pitch modulator
& flanger. Although this effect was originally intended for
guitar, it was also used by numerous keyboard players.
Used with electric piano, it produces a distinctive tone.

Increasing the Intensity value will strengthen the
modulation effect. This controls the effect, direct, and
feedback values. The values that are controlled will depend
on the Mode setting.

032: EP Chorus

This is inspired by a rare chorus built into an early version of
a famous modified tine piano.

033: St.HarmonicChorus
(Stereo Harmonic Chorus)
This effect applies chorus only to higher frequencies. This
can be used to apply a chorus effect to a bass sound without
making the sound thinner. You can also use this chorus
block with feedback as a flanger.
