Delay Bundle
Key Features
- Four distinct delay plugins (++delay, ++bubbler, ++pitchdelay, ++flipper) sharing a common hermite-interpolated delay engine with saturating feedback
- ++bubbler granular delay with 8-channel grain engine, MIDI-playable pitch distribution, and randomized grain parameters for ambient chordal washes
- ++delay offers up to 10 seconds of delay time with LFO modulation (5 waveforms), freeze mode, dual-head mode, and vintage-style feedback filtering
- ++pitchdelay delivers rotating-head pitch shifting with equal-tempered semitone, just ratio, cents, and octave controls for precise or extreme transposition
- ++flipper provides tempo-locked reverse delay for rhythmic backward textures synced to the host clock
- Saturating feedback loop with dc blocking across all four plugins doubles as a drone and noise generation tool
- Apple Silicon native (M1/M2) since v9.20, with support for VST, VST3, AU, and AAX formats on macOS and Windows
Description
The SoundHack Delay Bundle is a collection of four delay plugins designed by Tom Erbe, a professor of computer music at UC San Diego. Built around a shared core algorithm — a hermite interpolated delay line with variable modulation, dc-blocking feedback, and saturation — each plugin takes the concept in a distinct creative direction.
++delay delivers classic delay effects with up to 10 seconds of delay time, a wide-ranging filter section for emulating vintage delay characters, and an LFO modulator offering triangle, sine, ramp, square, and random waveforms. It also includes freeze mode, dual-head mode, feedback inversion, and full host tempo sync.
++bubbler is a granular delay that pulls grains from the delay line with randomized start time, reversal, panning, and pitch shift. Its 8-channel grain engine can produce extremely dense clouds of sound, and MIDI-playable pitch distribution turns it into an ambient chord generator.
++pitchdelay provides rotating-head style pitch shifting with controls for equal-tempered semitones, just ratios, cents, and octave offsets. Adjusting time and depth parameters transforms the pitch shifting from subtle detuning to wildly exaggerated effects.
++flipper is a tempo-synced reverse delay that records incoming audio and plays it back in reverse, producing rhythmic backward textures that respond best when locked to the host clock. The saturating feedback across all four plugins also makes them effective drone and noise generators.

Frequently Asked Questions
What plugins are included in the SoundHack Delay Bundle?
The bundle contains four plugins: ++delay (classic delay with modulation and filtering), ++bubbler (granular delay with MIDI-playable pitch shifting), ++pitchdelay (rotating-head style pitch shifter), and ++flipper (tempo-synced reverse delay). All four share the same core delay algorithm with saturating feedback.
Can ++bubbler respond to MIDI input?
Yes. ++bubbler distributes pitch shift values across its 8 grain channels, so you can play chords using the on-screen buttons or by sending MIDI notes to the plugin. This turns simple source material into ambient chordal washes.
Does the Delay Bundle support Apple Silicon Macs natively?
Yes. Version 9.20 added native Apple Silicon (M1/M2) support on macOS alongside Intel compatibility. The macOS installer includes AAX, VST, VST3, and AU formats.
Is the SoundHack Delay Bundle the same as the Delay Trio?
The Delay Trio was the original 2008 release containing ++delay, ++bubbler, and ++pitchdelay. The Delay Bundle adds a fourth plugin, ++flipper (reverse delay), and has been updated through version 9.20 with Apple Silicon support and VST3/AAX formats.
