Sawer - Effects


The effects are important to add 'polish' to your sounds. Sawer offers CHORUS, PHASER, DELAY and REVERB. To activate the effect, click on the 'ON' button next to the effect name (it will light red).


The Chorus effect results from the interaction of several copies of the original sound that are detuned by a very small and continuously variable amount. 'Chorus' is so called because it makes a single voice sound like a chorus of singers (all slightly out of tune relative to each other). Chorus creates a thick and lush texture. The Chorus in Sawer does not have a delay time control, rather delay time is modulated with the main LFO. With rate at which the pitch variations occur is controlled by "rate" knob.

  • DEPTH - Depth of the chorus detuning.
  • RATE - The speed at which the chorus voices change pitch (in Hz).
  • MIX - The amount of wet (effect) added to the dry sound (i.e. Full-Left is 100% Dry + 0% Wet, Full-Right is 100% Dry + 100% Wet).


Phasing is closely related to Flanging. Various frequencies in the original signal are delayed by different amounts, causing peaks and troughs in the output signal. Phasing and flanging sound similar, as both come from combining delayed versions of the signal with the original. However, the Phasing effect is significantly more intense, with a greater 'sweeping' effect across the spectrum.

  • CENTER - Center frequency around which the phase inversion occurs.
  • RATE - Controls the LFO detune speed between phaser voices.
  • DEPTH - Control the range (depth) of the phasing effect.
  • FDBK (Feedback) - Increases the amount of signal fed back into the phaser for a more complex sound.
  • MIX - Mix between the wet and dry signal. Effect level in other words.


Delay is an echo-based effect. Very short values of the delay time controls can produce a 'reverb' like sound while longer asymmetrical settings are great for left-right 'ping-pong' effects.

  • LEFT - Delay time for the left channel.
  • RIGHT - Delay time for the right channel.
  • FDBACK (Feedback) - Adjusts the level of the delay feedback. Greater levels produce more echoes.
  • M DEPTH (Modulation Depth) Delay Time Modulation Depth. This is an internal LFO that can modulate the delay time.
  • LO-CUT - Low Cut, sets a high-pass filter amount applied to the delay feedback loop. That is, the longer the tail of echoes, the less low frequencies they will contain. The sound becomes 'thinner'.
  • HI-CUT - High Cut, sets a low-pass filter amount applied to the delay feedback loop. That is, the longer the tail of echoes, the less high frequencies they will contain. The sound becomes 'darker'.
  • MIX - The amount DELAY effect added to the dry sound.


Reverb, short for reverberation, simulates acoustic spaces. If you clap your hands in a bathroom and in a concert hall, the two sounds will be quite different. In enclosed spaces reflections overlap one another to create a 'reverberant' sound. Sawer's reverb parameters allow you to simulate different types of acoustic spaces. If you want to give your patches a realistic (live) feel, then use of reverb is critical.

  • DECAY - The time it takes the reverberation to fade away. Higher values make the room sound like it has hard shiny surfaces. Lower values simulate more muted and padded surfaces.
  • HI-CUT - Changes the cut-off frequency of a low-pass filter. Use this to remove high frequencies from the reverb, or to make the room sound duller.
  • DAMP (Damping) - Damping, adjusts attenuation of the high frequencies in the reverb signal. Damping refers to the rate at which the high frequencies decay relative to the low frequencies. This level control causes the sound to become gradually muffled and warmer. The frequencies affected are controlled by the HI-CUT knob.
  • MIX - Mix between the wet (reverberant) and dry signal.
