Meet Jynth, the new synth by Fingerlab for iPhone, iPad and Mac — the warm, analog soul of the iconic Roland Juno-106, reimagined with a groundbreaking Physics Engine for organic, living sound. Designed for leads, basses, keys & pads, Jynth delivers that classic vintage character you love — housed in a meticulously crafted, photo-realistic interface that looks as good as it sounds. Shape your sound with a full analog-style signal chain: From the dual oscillators and resonant VCF filter to the ADSR envelope, LFO and built-in arpeggiator — every parameter has been carefully tuned to feel as musical as it sounds. Go further with 6 studio-grade effects: Tremolo, Flanger, Overdrive, Chorus, Delay & Reverb — stack them to build rich, evolving textures and cinematic soundscapes. Bring your presets to life with the Physics Engine: This is where Jynth truly stands apart. Assign up to 8 physics-driven modulations to any synth or effect parameter. Gravity, bounce, impulse, angle — let the laws of physics shape your sound in ways no LFO ever could. Every preset becomes unique, every performance feels alive. Explore new sonic territory with Preset Per Note & Preset Ribbon: Inspired by the music of Aphex Twin, Preset Per Note lets you assign a different preset to each key of the piano keyboard — so every note triggers an entirely different sound. Take it further with Preset Ribbon: select a collection of presets and glide between them in real time, simply by sliding your finger across the ribbon. A new way to perform. A new way to play. Play anywhere, plug into anything: Jynth is universal — one purchase gives you the full experience on iPhone, iPad and Mac. Use it as a standalone app or load it as an AudioUnit (AUv3) plugin directly inside your favorite DAW. Pair it with your MIDI controller via MIDI In support, and your sound is always there — even when your screen is off, thanks to Audio Background mode. Unlock the Full Version to access preset creation, all factory presets, FX, Physics Engine, Randomizer, Undo, Preset Per Note & Preset Ribbon.
