M4L Device: SA.Wash

Wash is a Max Audio Effect that uses comb filters to create a reverb style effect. The aim of the device is to create dense washes of sound (akin to a watercolour wash).

 

Parameters

  • del fb (delay feedback) : determines the amount of feedback, with higher values producing longer sustains.
  • del time (delay time): changes the length of time of the delay.
  • mod freq (modulation frequency): controls the frequency of the sine wave modulation oscillator. 
  • mod depth (modulation depth): changes the depth or amount of the modulation. 
  • jitter var (jitter variation): This modulation stage uses low pass filtered white noise, and the variation sets the cutoff frequency of the lowpass filter, with higher values producing more erratic variation. 
  • jitter depth: This parameter controls how much jitter is added to the delay time.
  • low cut: attenuates low frequencies from the effect
  • damping : attenuates high frequencies from the effect.
  • dry wet : fades between the dry and effected audio signals.
  • ef. gain (effect gain): scales the gain of the effect. This parameter is useful when the effect has high feedback settings as the volume can build up quickly.
  • clear button : In between the final two parameters is a button that will clear audio from the delays.

Note that changing the delay time, jitter, and modulation parameters will affect the pitch of the effected audio.
