	Name	Description
	Preset_DoubleKick	Sets the instance members to a preset.
	Preset_LongEcho	Sets the instance members to a preset.
	Preset_SmallEcho	Sets the instance members to a preset.

	Name	Description
	bStereo	Echo adjoining channels to each other? Default is disabled.
	fDelay	Delay in seconds (0<...n). Default = 0.
	fDryMix	Dry (unaffected) signal mix (-2...+2). Default = 0.
	fFeedback	Output signal to feed back into input (-1...+1). Default = 0 (disabled).
	fWetMix	Wet (affected) signal mix (-2...+2). Default = 0.
	lChannel	A BASSFXChan flag to define on which channels to apply the effect. Default: -1 (BASS_BFX_CHANALL) - all channels.

This is an echo effect that replays what you have played one or more times after a period of time. It's something like the echoes you might hear shouting against a canyon wall. For reverb effect enable feedback.

The fDryMix is the volume of input signal and the fWetMix is the volume of delayed signal. The fDelay is the delay time in sec. The fFeedback sets how much delay is feed back to the input (for repeating delays). If bStereo is enabled and a stream has an even number of channels then, each even channels will be echoed to each other.
