	Name	Description
	fDryMix	Dry (unaffected) signal mix (-2...+2). Default = 0.
	fFeedback	Feedback (-1...+1). Default = 0.
	fMaxSweep	Maximum delay in ms (0<...6000). Default = 0.
	fMinSweep	Minimum delay in ms (0<...6000). Default = 0.
	fRate	Rate in ms/s (0<...1000). Default = 0.
	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.

True vintage chorus works the same way as flanging. It mixes a varying delayed signal with the original to produce a large number of harmonically related notches in the frequency response. Chorus uses a longer delay than flanging, so there is a perception of "spaciousness", although the delay is too short to hear as a distinct slap-back echo. There is also little or no feedback, so the effect is more subtle.

The fDryMix is the volume of input signal and the fWetMix is the volume of delayed signal. The fFeedback sets feedback of chorus. The fRate, fMinSweep and fMaxSweep control how fast and far the frequency notches move. The fRate is the rate of delay change in millisecs per sec, fMaxSweep-fMinSweep is the range or width of sweep in ms.
