Chorus/Flanger; Other Parameters - Roland SD-90 Effects Manual

Audio Multi-Effects

Chorus/Flanger

Chorus:A sound with a subtly shifted pitch is added to the direct sound, making the final output sound thicker
and broader.
Flanger:The flanging effect gives a twisting, jet-airplane-like character to the sound.
CF SW (switch)
Off, On
Turns the chorus or flanger effect on/off.
CF Type (type)
Cho, Fln
Select the type of effect.
CF PreDly (pre delay)
0.1 – 3.2 – 30.0 ms
Adjusts the time needed for the effect sound to be output after the direct sound has been output. By setting a
longer Pre Delay time, you can obtain an effect that sounds like more than one sound is being played at the same
time (doubling effect).
CF Rate (rate)
0.05 – 0.4 – 10.0 Hz
Adjusts the rate at which the chorus is modulated.
CF Depth (depth)

Adjusts the depth of the Chorus effect. To use it for doubling, set the value to "0".
CF Fbk (feedback)
-98 – +70 – +98 %
Determines the amount of feedback.
Increasing the value will emphasize the effect, creating a more unusual sound. (Type = Fln only)
CF Bal (balance)
D100:0W – D50:50W – D0:100W
Adjust the balance between the effect sound volume and the direct sound volume.
