Modulation Delay

Apple

Modulation Delay is a versatile modulation effect plugin that generates chorus, flanging, and extreme modulation effects by combining variable delay time with two independent LFOs. It can produce anything from subtle doubling and chorus to metallic robot-like modulations and tape speed fluctuation emulations, making it suitable for both traditional modulation applications and experimental sound design.

Key Features

01Dual LFO modulation with independent rate control per channel
02Variable delay time for flanger, chorus, and resonator effects
03Feedback control with phase inversion for chaotic modulations
04De-Warble and Constant Mod buttons for pitch and modulation width stability
05D-Mode spatial filtering resembling vintage processor
06Phase control with 0° to 180° range for stereo/surround channel relationships
07Allpass filter with Low/High Cut frequency control for phase shifting
08Volume Mod and Output Mix sliders for effect amplitude and dry/wet balance

Things to Try

  • 01Set Time knob to far left position to create flanger effects
  • 02Set Time knob to center position for chorus effects
  • 03Set Time knob to far right position to hear clearly discernible delays
  • 04Use high Feedback values for strong modulations, or disable Feedback entirely for doubling effects
  • 05Use negative Feedback values to invert phase and create more chaotic effects
  • 06Turn on De-Warble button to maintain constant pitch of modulated signal
  • 07Turn on Constant Mod button to maintain constant modulation width regardless of modulation rate
  • 08Turn on D-Mode button to introduce spatial filtering effect in stereo or mono->stereo instances
  • 09Set Phase to 0° for simultaneous extreme modulation values across all channels
  • 10Set Phase to 180° or −180° for greatest possible distance between modulation phases of channels
  • 11Turn on Filter button to introduce allpass filter that shifts phase angle and influences stereo image
