Warning Always insert limiter after FeedbackPhaser. It can output very loud signal (slightly over +145 dB).

Quick Start

Below is an example setup steps.

1. Launch FeedbackPhaser.
2. Lower Output depending on the amplitude of input.
3. Change Feedback Amount.
4. Change Modulation Amount.
5. Change Safety Clip.

Output amplitude is mostly determined by above steps. After that, start changing other parameters.

Note that the character of Modulation Amount changes depending on Modulation Type.

Taming Feedback

Safety Clip is the most important parameter to limit output amplitude. if feedback amplitude exceeds Safety Clip amplitude, the text indicator:

Output is clean.

changes to:

Too much feedback.

Distortion will be added when "Too much feedback." is displayed. If distortion is not desired, increase Safety Clip, and decrease Output.

Sometimes increasing Safety Clip can't stop distortion. In this case, reduce Feedback Amount and/or Modulation Amount.

Where to Automate

Following parameters might be fun to automate.

• Allpass
  • Spread.
  • Center.
• Modulation
  • Mod. Asym..

Also, note event can be used to control Allpass Center.

More Allpass Stage adds more resonance for feedback. However, it also dilutes the texture of input signal.
