138. chorus

A pretty standard chorus effect.

in is the input signal.

rate is the LFO in Hz, (1.6 seems to work pretty well).

depth refers to the amount of modulation (0-1). small depth values (~0.01 or less) are ideal.

mix is wet/dry balance of the output (0 is 100% dry, 1 is 100% wet)

delay is the size of the buffer, in seconds. 0.1 seconds ought to be enough? This needs to be a constant. The longer the delay, the greater pitch variance there can be with the depth control.

(define (chorus in rate depth mix delay)
  (param in)
  (param rate)
  (param depth)
  (param mix)
  (param delay)
  (rvl "chorus"))
