typedef struct 
{ 
   long lDryMix; 
   long lWetMix; 
   long lDelay; 
   long lFeedback; 
   BOOL bEnabled; 
   long lDDryMix; 
   long lDWetMix; 
   long lDDelay; 
   long lDFeedback; 
   BOOL bDEnabled; 
} ECHO_ATTRIBUTES;

Describes the echo attributes.

Name	Description
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 echo. 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.
bEnabled	Indicates whether the echo 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 depth value. Original default value is 500.
lDFeedback	Default feedback value Original default value is 25.
bDEnabled	Default for bEnabled value Original default value is TRUE.
