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 5 studio-grade effects: Tremolo, Flanger, 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.

GCS Model 8 is a free, pocket-sized 8-track tape DAW for iPhone. It has a full blown physics engine which runs in the background and models classic reel-to-reel machines and various formats ranging from LoFi cassette to HiFi 1" tape. The engine is the exact same as the one used in the professional desktop recording version, but still runs very nicely on iPhone. GCS Model 8 for iPhone is completely free, with no in-app purchases, subscriptions, or ads. I really want people to have the engine as a fun tool for mobile settings without any sort of catch. Features: • 8-track recording with a real tape transport (play, record, rewind, fast-forward, punch, scrub) • Analog tape physics: adjustable wow, flutter, stickiness, head gap, hiss, and age • Built-in effects and tape techniques: reverse, SOS, punch, click track, loop • Built-in instruments: A-1 Mono Synth, A-10 Poly Synth, Glissandio (Ondes Martenot style slide synth), Stage Keyboard • Voxtone Drum Machine: synthesized analog drums with a dedicated step-sequencer (MATRIX) and live-trigger (PADS) view, plus two sample-based kits (808, Acetone) • 8-pad MPC-style Pad Sampler: load your own samples or mic them in directly, with pitch, trim, and gate controls • Reels: save, load, and share your sessions • Bluetooth MIDI keyboard support • Importing recordings to hit them to tape • Sound of Sound looping (Fripp style) • Formats: cassette, 1/4", 1/2" and 1" - along with various presets •Most of the features found on the desktop version Reels you create on iPhone move over to GCS Model 8 for iPad and GCS Model 8 for Mac/Windows, which add more tracks, more effects, and full export/mixdown for when you're ready to take a session further.
