Members
- fWetDryMix
- Ratio of wet (processed) signal to dry (unprocessed) signal. Must be in the range from DSFXCHORUS_WETDRYMIX_MIN through DSFXCHORUS_WETDRYMIX_MAX (all wet).
- fDepth
- Percentage by which the delay time is modulated by the low-frequency oscillator, in hundredths of a percentage point. Must be in the range from DSFXCHORUS_DEPTH_MIN through DSFXCHORUS_DEPTH_MAX. The default value is 25.
- fFeedback
- Percentage of output signal to feed back into the effect's input, in the range from DSFXCHORUS_FEEDBACK_MIN to DSFXCHORUS_FEEDBACK_MAX. The default value is 0.
- fFrequency
- Frequency of the LFO, in the range from DSFXCHORUS_FREQUENCY_MIN to DSFXCHORUS_FREQUENCY_MAX. The default value is 0.
- lWaveform
- Waveform of the LFO. Defined values are DSFXCHORUS_WAVE_TRIANGLE and DSFXCHORUS_WAVE_SIN. By default, the waveform is a sine.
- fDelay
- Number of milliseconds the input is delayed before it is played back, in the range from DSFXCHORUS_DELAY_MIN to DSFXCHORUS_DELAY_MAX. The default value is 0 ms.
- lPhase
- Phase differential between left and right LFOs, in the range from DSFXCHORUS_PHASE_MIN through DSFXCHORUS_PHASE_MAX. Possible values are defined as follows:
- DSFXCHORUS_PHASE_NEG_180
DSFXCHORUS_PHASE_NEG_90
DSFXCHORUS_PHASE_ZERO
DSFXCHORUS_PHASE_90
DSFXCHORUS_PHASE_180
