lDryMix

Controls the level of unprocessed signals. Adjust to control the pass-through volume of the unprocessed signal.

lWetMix

Controls the level of processed signals. Adjust to control the pass-through volume of the processed signal.

lDelay

Controls the level of the chorus effect. Larger values result in greater delay times.

lFeedback

Feedback of the repeated signal, by default from -100 to 100. Zero feedback will result in only a single repeat, while nonzero feedback settings will generate numerous repeats.

lStereo

Stereo represents the phase difference between the left and right channel.

bEnabled

Indicates whether the chorus effect is enabled (TRUE) or not (FALSE).

lDDryMix

Default Dry Mix value.

Original default value is 70.

lDWetMix

Default Wet Mix value.

Original default value is 50.

LDDelay

Default delay value.

Original default value is 500.

LDFeedback

Default feedback value

Original default value is 25.

lDStereo

Default stereo value

Original default value is 90.

bDEnabled

Default for bEnabled value

Original default value is TRUE.
