4-track sampler / sequencer Naive tracker is a modern, minimalistic implementation of the vertical sequencer concept known as "tracker", designed specifically for small screens with touch interface and optimized for a fast and easy workflow. - single screen editor: immediate access to everything - sleek monochrome UI - ready to use: comes with a collection of synthetic lo-fi and acoustic instrument samples - sample browser: load / play samples super fast from anywhere in the file system - record samples - sample editor: select, trim, normalise, reverse or draw the raw wave form - random: shuffle parameters for new inspriration - pattern list: switch patterns live, chain patterns in a loop or arrange a song - export / re-sample: save complete songs as wav file - Ableton Link: plays in sync with any Link enabled app/device The two-dimensional note editing with instant transpose function enables a clear and compact sequencer where everything happens in a single layer. Patterns can be selected manually, play as looped range or in linear order so that the pattern column is suited for live performance as well as song arrangement. The 16-step sequencer grid may be extended with meta step, variable track length or by looping a chain of patterns. Specs - 4 tracks - 16-step sequencer with variable track length - 8 samples, max. 2.7 sec. each - 16 patterns - 256 patterns song length Sequencer parameters - note value (octave / semitone) - pitch envelope - pitch LFO - AD / gate / D envelope - volume / panning - offset / loop length - filter high / low pass - meta (play steps conditionally) No in-app-purchases, no subscription, no ads, no AI.

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.
