Function fluidlite_sys::fluid_synth_set_chorus

pub unsafe extern "C" fn fluid_synth_set_chorus(
    synth: *mut fluid_synth_t, 
    nr: c_int, 
    level: f64, 
    speed: f64, 
    depth_ms: f64, 
    type_: c_int
)

Set up the chorus. It should be turned on with fluid_synth_set_chorus_on. If faulty parameters are given, all new settings are discarded. Keep in mind, that the needed CPU time is proportional to 'nr'.
