386 Chapter 24 EVP88
Chorus
The well-known chorus effect is based on a delay circuit, the delay time of which is
permanently modulated by an LFO, while the delayed effect signal is mixed with the
original dry signal. It is the most popularly used effect on electric piano sounds. The
single parameter regulates the intensity (the amount of delay time deviation), while the
LFO rate is fixed at 0.7 Hz. Pay close attention when using high values as this may result
in the piano sounding detuned.
