Tonic Synth vs PolyrhythmLab

Eight sound engines in one instrument — and a whole preset community living inside it. Physical modeling, virtual analog, 3D wavetable, 6-operator FM and a full SoundFont player: stack up to three engines per sound, each with its own filter, envelope and modulation. Play it standalone on iPhone, iPad and Mac, or load it as an AUv3 plug-in — instrument and effect — in your favorite host. One purchase. No subscription, no ads, nothing locked behind a paywall. • TONICA — THE SOUND COMMUNITY Your next signature sound might come from a player on the other side of the world. Browse what the community publishes without ever leaving the app: one tap auditions it under your fingers, two taps keep it. Love an author? Take their whole collection at once, into a bank named after them. And publish yours with a single tap — no account, no sign-up, no cost. • THREE OSCILLATORS Up to three independent layers — each with its own source, filter, envelope and modulation, plus mute/solo and keyboard split. From a simple patch to a fat, detuned stack on one spread knob. The Vector pad morphs across all three layers in real time: draw a path and the sound travels it on its own. • SOUND ENGINES Per layer: physical modeling (string, modal, wind, bowed), virtual analog (sine, saw, square, triangle, pulse and super-saw, with sub-oscillator and noise), wavetables up to 128 frames, SoundFont (.sf2 and compressed .sf3) and 6-operator FM that opens .syx cartridges. Record anything through the mic and turn it into a wavetable — or draw the waveform with your finger and hear it instantly, on a 3D landscape you can drag, rotate and resize. • FILTERS Eight analog-modeled voicings — LP/HP/BP/Notch, 12 or 24 dB per octave, resonance into self-oscillation, drive and 4× oversampling. From warm ladder to creamy SVF, from acid squelch to screaming resonance. • ARPEGGIATOR & SEQUENCER A step editor with a live playhead: ties, ratchets, accents and per-step probability, polymetric rhythm masks, capture of what you just played, swing, gate mode, key range and per-layer arping. Imports .mid patterns, follows MIDI Clock, and with Hold the pattern runs by itself. • EFFECTS RACK Chorus, tempo-synced ping-pong delay, 6-type FDN reverb, 5-band EQ, compressor and a Flanger/Phaser module — each one switchable and routable per layer. • BUILT FOR THE STAGE Six scenes (A–F) swap the entire patch live without cutting the sound: the note ringing out finishes naturally while the next one already speaks with the new tone. Switched apps mid-set? A sustain pedal left down or a mod wheel parked halfway no longer hijacks your sound — every control starts working again the moment you move it. The MIDI filter decides what each pedal, wheel or controller is allowed to do, and can target one specific device when there's more than one keyboard in the rack. Program Change and Bank Select switch sounds from your controller. MIDI Learn on any control, over USB or Bluetooth. • YOUR LIBRARY 280+ factory sounds in banks, and your own collection beside them: favorites, renaming, saving, tagging and search by name, tag or bank. Two file formats of its own — one to share sounds (.tpr) and one for a full library backup (.tbk). Double-click a file, or receive one by AirDrop, and it merges straight in without duplicating anything. • WHERE IT RUNS iPhone, iPad and Mac, from a single purchase. As an AUv3 it runs in the major recording apps on iOS and macOS. Using software that doesn't load AUv3 yet? See rsjb.com.br/support for the route other users have already proven.

PolyrhythmLab is a groovebox built around true polyrhythms: every sound layer gets its own step count, pulse count, and rotation, so layers of different lengths interlock and drift in and out of phase instead of locking to one shared grid. GROOVEBOX • Euclidean-style rhythm engine — set steps, pulses, and rotation per layer • Drums, glitch/textural one-shots, classic synth voices (piano, bell, pad, bass), and melodic synth patches • Per-layer filter, reverb, delay, pitch, and LFOs on every parameter • Randomize engine biased toward musical, playable combinations • Chord modes, scales, and modal note selection for melodic layers SONG MODE Arrange your saved patterns into sections and chain them into a full song. VJ MIX A live visual performance surface: blend two audio-reactive visualizations, layer on real-time color and shader effects — RGB split, kaleidoscope, pixelate, glow, trail — and a 3D camera with zoom, pan, orbit, and tilt, each with its own LFO. Randomize the whole look by hand, or hand it to an autonomous "robot" that keeps remixing itself. Record the performance in real time via ReplayKit, or export a styled video clip. CAST TO ANY SCREEN Send the VJ Mix visuals to a TV or projector over AirPlay or a wired adapter, while your device keeps the full set of live controls. PRESETS Save and reload both groovebox patterns and VJ Mix setups — visual styles, effects, camera moves, and their LFOs — as named presets. EXPORT Render your patterns and songs to audio, or export them as MIDI. No account, no ads, no analytics. Everything is stored locally on your device.
