Read full descriptionHide full description
Turn your music into live, reactive visuals, right from your iPhone, iPad, and Mac. The whole app now speaks 15 languages. ImmerGround is a music-reactive visual instrument for musicians, VJs, DJs, producers, and performers: a music visualizer you can play like an instrument. Start from a shader or bring your own video and images, map them to audio and MIDI, and watch every beat, note, and frequency reshape the picture in real time. ImmerGround is free to start, and anyone can create projects. ImmerGround Pro, an optional auto-renewing subscription, unlocks the Pro shaders and effects, sharing, and renders up to 4K. FEATURES Shaders That Move to Your Music: 28 generative scenes, from cymatics and city skylines to ink, posters, petals, and glyph storms. Every scene has four knobs of its own, already mapped to the music, so it moves with your track from the first second. Save a look as a preset and bring it back in one tap. Your Music, in Sync: Play songs from your files or your music library, build setlists, or use the mic. Open a streaming panel in the Music sheet: it plays in its own app and ImmerGround hears it through the mic. Music keeps playing in the background. The Music Clock follows tempo and beats live, so effects and pad scenes land on the beat. On Mac, visuals can also follow music playing in any other app. Audio-Reactive in Real Time: Split the spectrum into Sub, Bass, Mid, High, and Air, or dial in your own frequency window. Full MIDI Mapping: Connect any MIDI controller and map CC knobs, notes, pitch bend, and pads to anything on screen. Built-in MIDI Learn binds a control in one move. A Rack of Effects: Pixelate, glitch slicing, RGB split, zoom pulse, strobe, and more, plus eight effect packs: Kaleidoscope, ASCII, Motion Track, Old TV, Print, Film, Flow, and Depth. Stack and modulate them into a look of your own. Precise Source-to-Effect Routing: Pick a source (a bass band, a MIDI knob, a held note), pick a destination (glitch amount, zoom, kaleidoscope sides, playback speed), and shape how one drives the other with response curves, output ranges, and smoothing. Build as many links as you like, all at once. Trigger Mode, Pad Scenes & Video Cues: Load a bank of clips and images and fire them from pads. Split a video into pads and jump to any moment with a tap, a key, or a MIDI pad. Play setlists, not settings. Multi-Layer Compositing: Stack video, image, and effect layers with blend modes and opacity. Store: Free CC0 VJ loops you can use anywhere, plus shader looks and effect packs, right on the library page. In Your Language: ImmerGround now speaks English, Deutsch, Español, Français, Italiano, 日本語, 한국어, Nederlands, Polski, Português (Brasil), Русский, Svenska, Türkçe, 简体中文 and 繁體中文. Projects That Remember: Unlimited projects, saved automatically, with undo and redo that survives across launches. Built for the Stage and the Studio: A fast, hardware-inspired interface designed for live control. Send the show to a projector or second screen over HDMI or AirPlay. Hit REC to capture your set, or render it offline up to 4K. Universal across iPhone, iPad, and Mac. From bedroom jams to club walls, ImmerGround makes expressive visual performance accessible. Bring your sound to life. SUBSCRIPTION ImmerGround Pro unlocks every Pro shader, effect pack, and loop, sharing and export, and renders up to 4K. It is available as a weekly or annual auto-renewing subscription. Payment will be charged to your Apple Account at confirmation of purchase. Your subscription automatically renews unless it is canceled at least 24 hours before the end of the current period. Your account will be charged for renewal within 24 hours prior to the end of the current period. You can manage or cancel your subscription anytime in your App Store account settings. SAY HI!

055U4RY (say it: "ossuary") is an 8-voice polyphonic synthesizer sealed inside a haunted DOS terminal — and, since 1.30, a second plug-in that turns the same machine loose on any audio you feed it. A photographic ASCII skull is the front panel: its jaw hinges open with the amplitude envelope, its eye sockets ignite with the output level, and the whole interface tears, melts and reassembles itself while you play. THE VOICE - 15 synthesis engines: detuned saw/square/triangle unison stacks, sine and sub-oscillators one and two octaves down, two-operator FM, ring modulation and inharmonic partials. Every factory preset is a different engine. - Twin chaotic LFOs that cross-modulate each other's RATE, so pitch and filter drift never repeats. Held notes stay alive and slightly wrong. - A Shepard-Risset layer tuned beneath every note: five windowed partials in an endless downward glissando - the bottomless-pit illusion of classic horror scoring, fused into the oscillator core. - A 19 Hz infrasonic tremolo at the edge of perception. On headphones it is a shiver; on a big system it is pressure. THE CHAIN - State-variable filter, low-pass or band-pass per engine, with resonance that will scream - Sample-rate reducer and bit-depth crusher for terminal-grade lo-fi - Saturating drive stage - GLTCH: a real-time stutter buffer that seizes and re-loops your signal - CRYPT: a damped, pitch-black comb/allpass reverb - GLIDE: exponential portamento up to 1.5 seconds - DOOM: one macro that leans the chaos, the descent and the tremor deeper into the signal PERFORM - 14 knobs, all ASCII, every one audible on every preset - 15 factory presets with per-preset patch memory: your tweaks persist for each preset, and [RESET] restores the factory sound - Two-octave on-screen keyboard with octave transpose and note names - Hardware MIDI in (all sources auto-connect), built-in Bluetooth MIDI pairing, pitch bend, MIDI 2.0 aware - The skull is your meter: jaw = envelope, eyes = level, decay = how hard you push GLTCH 055U4RY FX - THE EFFECT The same app installs a second, separate plug-in. Put it on a drum loop, a guitar, a vocal or a whole mix and run it through the machine: - The full destruction chain as an insert - drive, bit crusher, sample-rate reducer, stutter, filter and the CRYPT reverb - in true stereo - HAUNT: a cross-fed delay whose repeats rot as they decay, with MURK controlling how fast they turn to mud - SYNC: stutters and echoes locked to your host's tempo, 1/16 through 1/1, or free-running - DOOM as an injector: the endless Risset descent and the 19 Hz tremor printed underneath your audio, so anything you feed it gains a bottomless falling drone that was never in the source - Fifteen presets sharing the instrument's names, each a different topology - Wet/dry MIX, output trim, and a skull that reacts to whatever passes through AUv3 + STANDALONE The synth runs standalone with zero setup. Both plug-ins install into your host: AUM, Logic Pro, GarageBand, apeMatrix, WBTRK and any AUv3-compatible DAW, with full parameter automation - "hejluxom: 055U4RY" under instruments, "hejluxom: 055U4RY FX" under effects. One purchase, every platform: iPhone, iPad and Mac. No accounts, no ads, no data collected - your patches never leave the device.
