Eventide Audio releases Blackhole Reverb, UltraTap Delay and MicroPitch for iPhone and iPad


Eventide Audio has released three new iOS music creation and live performance effects apps from their legendary catalogue of studio hardware and software: Blackhole Reverb ($19.99), UltraTap Delay, ($14.99) and MicroPitch ($9.99) for iPhone and iPad.

Blackhole Reverb for iOS is designed to break the rules by allowing musicians, producers and sound designers for film and game audio to create virtual spaces on their iPhone and iPad that could never exist in reality. At large sizes, Blackhole Reverb's soft attack and lingering, harmonic tails allow it to shine on guitars, strings, vocals and pads. At small sizes, those very same qualities can add an angelic sheen to vocals or turn a simple drum track into an otherworldly rhythm section.

Derived from the original hardware versions of Eventide's flagship studio processors and the popular "Space" pedal, the original Blackhole Reverb was created as "an abnormally large reverb, sucking everything into a bottomless chamber." Later in the Mac/PC plug-in version, the meta-controls offered by the added Ribbon and Hotswitch allowed musicians to musically manipulate multiple parameters for enhanced playability. Blackhole Reverb's otherworldly sound designs have been used on hundreds of recordings and science fiction films: for Prometheus it created the large cavernous soundscapes that evoked eerie, unsettling sensations. Skywalker Sound has used it on numerous film productions to create massive explosions and searing light-sabers and it can be heard throughout Blade Runner 2049's soundtrack enhancing the film's disturbing atmosphere.


  • Over 50 presets; many created by Eventide artists, such as Black Violin, Vernon Reid, Jakob Haq, MIKNNA, and many more.
  • Ability to create musical effects useful for highlighting key instruments.
  • Supernatural settings for abstract spatial effects and drones.
  • Subtle settings for ambient washes and track highlighting.
  • Unique "Gravity" control reverses the arrow of time by inverting the reverb's decay.
  • Innovative Ribbon and Hotswitch allow for 'playing' the effect by changing any combination of parameters seamlessly and simultaneously.
  • Fully flexible mono and stereo options bring new realms of stereo imaging to mono instruments.
  • Employ "Mix Lock" to scroll through presets while keeping the wet-dry mix constant.
  • Available as an Audio Units AUv3 plug-in, Inter-App Audio, and as a standalone app for iPhone / iPad.

UltraTap Delay for iPhone and iPad is designed to be a versatile, multi-tap delay effect capable of rhythmic delays, glitchy reverbs, wacky comb-filtering and huge pad-like volume swells by employing modulation techniques. Creative controls like "Slurm" for juicy tap slurring, glitched auto-volume chopping and enormous swell features for breakbeats or atmospheric rises make it the perfect tool for creating drum fills, vocal choruses, swelling guitar chords and other evolving effects. UltraTap Delay for iOS can create everything from reversed reverbs to a massed church choir singing a Gregorian chant in a cathedral. With playable Ribbon and Hotswitch meta controls, it's intended for sound designers, DJs, EDM, Trap, Hip-Hop producers and musicians for creating, enhancing and performing music.


  • Up to 64 taps to create simple repeats or morph delays into choruses and reverbs.
  • Control for speeding up or slowing down of the rhythmic spacing between taps using the Spread knob.
  • Onboard LFOs and envelopes to chop sound sources into stuttered rhythms.
  • Innovative "Slurm" control to smear taps together or modulate them to create truly unique reverbs and 'mushy' stutter effects.
  • Stereo image control of taps to alternate between hard-panned and mono.
  • Over 150 presets designed to inspire, including artist presets by Chris Carter, Colin Newman, Sasha, Jakob Haq and many more.
  • Playable Ribbon and Hotswitch allow for changing any combination of parameters simultaneously.
  • Use "Mix Lock" to scroll through presets while keeping the wet-dry mix constant.
  • Available as an Audio Units AUv3 plug-in, Inter-App Audio, and standalone app for iPhone / iPad.

MicroPitch for iOS allows musicians to mix in detuned and delayed versions of a signal. It creates depth and dimensions never before possible, with expanded controls for deep pitch dives, haunting echoes, and pristine chorusing effects. MicroPitch's included playable Ribbon and meta controls make it the perfect companion app for live performance on stage, or as a plug-in for popular iOS DAWs for use in the studio on all genres of music. MicroPitch is one of the effects that put Eventide Audio on the map - with origins in Eventide's legendary studio hardware - the H3000, H949 and H910 Harmonizer.


  • Two voices of pitch shifting, one from unison to -50 cents, the other from unison to +50 cents, each with up to 2 seconds of delay.

  • Feedback control to perform pitch dive or rise effects.

  • Innovative Ribbon control allows for changing any combination of parameters simultaneously.

Eventide Co-Owner, Tony Agnello says: "Entering into the iOS music creation ecosystem is an exciting new horizon for Eventide. Beginning years ago with our 'Factor' series of guitar pedals, our mission has been to put studio-quality performance effects within the grasp of all artists. A decade ago audio production techniques evolved from the exclusive world of the recording studio and expensive consoles to working 'in the box.' Eventide is now focused on partnering with Apple to help take the next step – moving music creation and audio production from 'in the box' to 'in the hand.' We also believe that each effect should be a 'playable' instrument in its own right and so we've developed our innovative 'Ribbon' control to unleash a new level of instant creative control. Our first three releases for iPhone and iPad - Blackhole Reverb, UltraTap Delay and MicroPitch - offer just that, playable effects processors and sound design tools for mobile musicians and producers, in every genre, from beginner to professional."
