Morphimus

Read full description

Morphimus is a playful, touch-first synth playground that turns simple gestures into rich, musical sound. Tap bubbles, slide the rainbow strip, spin the orbit wheel, glide along the tone stream, and jam drum pads to shape bright plucks, dreamy clouds, punchy beats, zappy FX, and flowing wave textures. With expressive live controls, colorful motion, and fast, responsive audio, Morphimus offers a fresh, hands-on way to explore music on iPhone and iPad. With advanced randomization features, exploration is at the heart of the experience. Re-roll the individual sound flavors to get a vastly different timbre, or use the global re-roll to roll a random combination of play style, sound flavor, key, and effects. You can also save and recall your favorite sounds.

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.
