Pulsar (Delay)

Delay

Pulsar Device

Essentials

Pulsar is a stereo delay effect designed for rhythmic, spatial, and creative audio manipulation. Combines two independent pre-delay paths (left and right) with a synchronized feedback delay circuit, LFO modulation, filter section, stereo cross-swapping, and wet/dry mixing. Perfect for wide stereo delays, rhythmic patterns, and creative spatial effects.
  1. Independent left/right pre-delay paths with individual panning
  2. Shared feedback delay circuit with LFO modulation
  3. Filter section (highpass and lowpass)
  4. Stereo cross-swapping in feedback loop
  5. Comprehensive wet/dry mixing

Pre-delay

Pulsar Pre-delay
Sync (L/R) When enabled, each channel's pre-delay time syncs to the project tempo
ms (L/R) Sets the delay time for each channel in milliseconds (0 to 500 ms, if Sync is off)
Pan (L/R) Positions each pre-delay in the stereo field independently (-100 = fully left, 0 = center, 100 = fully right)

Feedback delay

Pulsar Feedback delay
Sync Syncs the feedback delay time to the project tempo
ms Manual control of feedback delay time when sync is disabled (0 to 500 ms)
Rate LFO speed for modulating the feedback delay time (0.1 to 25 Hz)
Depth LFO modulation depth for the feedback delay time (0 to 50 ms)
Feedback Sets how much of the delayed signal is fed back into the delay input (0 to 100%). Higher values create more repeats

Filter

Pulsar Filter
HP filter Highpass filter cutoff frequency (20 to 20000 Hz); removes frequencies below the set point
LP filter Lowpass filter cutoff frequency (20 to 20000 Hz); removes frequencies above the set point
Stereo Cross Controls channel swapping on each feedback cycle (0 to 100%). 0% = no swap, 50% = mono, 100% = fully swapped (ping-pong in feedback loop)

Output

Pulsar Output
Dry Sets the level of the original (unprocessed) signal
Wet Sets the level of the processed signal
On/Off Activates or bypasses the effect

Practical Tips

Practical Tips

  • Tempo-synced Echoes: Sync both pre-delay and feedback delay to the BPM for rhythmic effects that align with your track.
  • Ping Pong Delay: Use different pre-delay times and pan settings on left/right channels to bounce delays between speakers.
  • Dub Delay: Push feedback high and filter the loop for resonant, analog-style decay.
  • Stereo Ambience: Add subtle delay and use Stereo Cross for ping-pong effects in the feedback loop.
  • Sound Design: Modulate feedback delay time with Rate/Depth LFO for chorus, flanging, or pitch drift effects.
  • Use feedback carefully. High values can create infinite loops and even self-oscillation.
  • Automate the filter or Stereo Cross for evolving spatial effects.
  • Combine with other effects like reverb or distortion for advanced layering.
