Bouncit: Stereo Delay / Echo

Bouncit free stereo delay & echo plugin UI

A BPM-synced stereo delay for grooves that bounce.

Bouncit is a tempo-synced stereo delay with independent left/right timing, a filtered and saturated feedback path, tape-style modulation, ducking, swing, freeze, and stereo-width control.

macOS (Apple Silicon and Intel): AU, VST3, CLAP, AAX, Standalone. Signed and notarized by Apple.

Windows 10 and 11, 64-bit: VST3, CLAP, Standalone. Authenticode signed.

AAX ships on macOS only.

🎛️ Features

  • Tempo-synced delay: Sync to host BPM across 6 note values (1/32, 1/16, 1/8, 1/4, 1/2, 1/1), or switch off Sync for free time (1–2000 ms).
  • Independent L/R timing: Link both channels together, or set each side separately for ping-pong effects.
  • Feedback: 0–95%, with an internal Freeze mode that loops the delay buffer infinitely.
  • LP Filter: Low-pass tone shaping in the feedback path (200 Hz – 20 kHz).
  • HP Filter: High-pass in the feedback path (20 Hz – 2 kHz) to keep repeats out of the low end.
  • FB Saturation: Tanh saturation in the feedback loop (0–100%) for repeats that grow warmer as they decay.
  • Ducking: Delay repeats duck out of the way when the input signal is present (0–100%).
  • Mod Rate / Mod Depth: LFO modulation of the delay time (0.01–5 Hz rate, 0–100% depth) for tape-style pitch wobble.
  • Stereo Width: Mid/side width control on the wet signal, from mono (0%) to extra-wide (200%).
  • Swing: Offsets the right-channel delay for a shuffled, grooving feel (0–100%).
  • Mix: Dry/wet blend (0–100%) for series or parallel use.
  • Output: Output level trim (−24 to +6 dB).
  • Freeze & Bypass: One-click infinite-hold and true bypass with a click-free crossfade.
  • Preset menu: 14 factory presets, selectable from the UI.
  • A/B compare: Snapshot two settings and flip between them instantly.
  • Randomize: Generate a fresh starting point with one click.
  • User presets: Save and load your own .preset files.

🔬 Under the Hood

  • TPT feedback filters: Low-pass and high-pass filters run inside the feedback loop using a topology-preserving state-variable design for stable, allocation-free per-sample cutoff changes.
  • Anti-aliased saturation: Both the feedback saturator and the output soft-clipper use first-order antiderivative anti-aliasing (ADAA) to keep the drive clean.
  • DC blocker: A one-pole ~10 Hz high-pass in the feedback loop prevents DC build-up in long-decay repeats.
  • Fractional delay: Linearly interpolated delay reads with smoothed delay times for click-free timing and subdivision changes.
  • Output safety: A soft-clip stage plus a hard ceiling and NaN/Inf guards protect the output at all times.
  • Universal binary: Native on Apple Silicon and Intel.
