Tonic AP is a physically modelled acoustic piano: every note is calculated the moment you play it, from the hammer, the strings and the wooden soundboard — not from recordings. It runs as an app and as an Audio Unit (AUv3) instrument in GarageBand, Logic, AUM, Cubasis and any host on iPhone, iPad and Mac. PHYSICAL MODELLING, NOT SAMPLES No recorded velocity layers: hit harder and the felt compresses and the tone OPENS, from a velvet pianissimo to a steely fortissimo, with no step between layers. The strings of each key ring together at the bridge, the soundboard sings after the strike and, with the pedal down, the whole piano resonates. No library to download: the app is light and switches sounds instantly. BUILD YOUR OWN PIANO You choose the parts and the piano is recalculated around them: • Model — a grand, from living-room to concert size (1.5 to 2.9 m), or an upright, with its height and distance from the wall. • Soundboard — four woods and the thickness. • Hammers — five felts (from soft to lacquered, plus Felt, the felt-piano strip), the hardness at pp and ff, the strike point and the balance from bass to treble. • Strings and dampers — unison, sustain, damper, resonance, duplex, the damper position and the last damper. • Tuning — pitch, stretched tuning and seven historical temperaments. • Condition — from a brand-new piano to a saloon piano. • Key by key — the tuning, level, hammer, sustain and unison of each of the 88, the way a technician voices them, or a ready-made profile: warm bass, singing treble, well-worn, honky-tonk. CHOOSE HOW YOU LISTEN Place up to eight microphones around the piano, each with its own pattern (omni, cardioid, figure-8), level and pan — or listen binaural on headphones, with the head wherever you like. Or start from a ready-made setup, the ones engineers use: spaced pair, XY, ORTF, Blumlein, a three-omni tree, close pop/jazz, a mic under the soundboard, the audience pair and the player's ears. Pick the room — studio, living room, chamber, concert hall or church —, drag its corner to resize it and change the walls: wood, plaster, stone, curtains or studio. The lid opens and closes. REAL PEDALS Continuous sustain (half-pedalling works), sostenuto and una corda. And the rarer pedals, for exploring: celeste, harmonic, Mozart rail, buff stop, super sostenuto, rattle and pinch harmonic. A PIANO RACK 5-band EQ, compressor, exciter, 8-mode chorus, delay, a reverb with 9 spaces and a limiter. 34 effect presets change the effects without touching the piano. BUILT FOR THE STAGE Six scenes per sound (A–F). MIDI Learn on any control. Nine velocity curves plus Fixed, sustain, sostenuto and una corda over MIDI, Program Change and PANIC. One voice per key, as on a piano: a ringing note is never cut to make room for another. 46 FACTORY SOUNDS In 6 banks: Concert Grand, Studio Grand, Parlor Grand, Upright, Character and Stage & FX — every wood, felt, condition, room and effect appears in at least one. Favourites, search, tags, import and export — and your sounds stay yours when the app updates. LEARN BY PLAYING Turn on the guided tour and touch a knob: it tells you what that part does to the sound. USING IT AS A PLUG-IN Open Tonic AP once after installing and ask your host to rescan plug-ins: that is what registers the Audio Unit. Sounds, scenes and MIDI maps are the same in the app and the plug-in. Thank you for playing with RSJB — made by musicians, for musicians! Follow the news at www.rsjb.com.br ## Is Tonic Piano safe?
