MIDI Implementation
●0141: Tremolo Chorus
This is a chorus effect with added Tremolo (cyclic modulation of volume).
●0143: Space D
This is a multiple chorus that applies two-phase modulation in stereo. It gives no
impression of modulation, but produces a transparent chorus effect.
●0144: 3D Chorus
This applies a 3D effect to the chorus sound. The chorus sound will be positioned 90 degrees
left and 90 degrees right.
●0145: 2Band Chorus
A chorus effect that lets you apply an effect independently to the low-frequency and high-
frequency ranges.
