{ 
   long lDryMix; 
   long lWetMix; 
   long lDelay; 
   long lFeedback; 
   BOOL bEnabled; 
   long lDDryMix; 
   long lDWetMix; 
   long lDDelay;

   BOOL bDEnabled; 
} ECHO_ATTRIBUTES; 

Members

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.
