Thirty-four effects. One tap to add each one — and the order of the chain is yours. Tonic FX is the Tonic effects rack in an app of its own, focused and affordable — an Audio Unit (AU and AUv3) effect in GarageBand, Logic, AUM, Cubasis, Drambo and any host, and a standalone app that processes your microphone or line input. A RACK YOU BUILD — AND REORDER Every effect has its own on/off, grouped by category: add one with a tap, then drag the cards to rearrange the chain. The order is saved with the preset. THIRTY-FOUR EFFECTS • Drive — Overdrive, Distortion (hard, asymmetric and fuzz), Amp Sim with 6 models and cabinet, Wavefolder/Fuzz, Bitcrush, Ring Modulator and Lo-Fi/Vinyl. • Modulation — an 8-mode Chorus (vintage through string ensemble), a Phaser with four voicings, from the gentle 4-stage pedal to a slow 10-stage pad sweep, Flanger, Vibrato, Detune, Pitch Shifter/Harmonizer, Throb (the pulsing vibrato of the sixties) and Frequency Shifter. • Motion — a two-rotor Rotary cabinet, Auto-Pan, Tremolo, a Stereo Widener with a mono maker that keeps the bass centred, a Pedal Wah you can put under an expression pedal, and the Trance Gate, with a draw-your-own-rhythm mode. • Time — a tempo-syncable ping-pong Delay, with Wow and Sat for tape character; a Reverb with nine spaces: room, hall, cathedral, plate, spring, shimmer, cloud, gated and swell — plus Freeze, to hold a chord and play over it; Reverse, which plays back what you just played backwards; and Call & Response, which listens to your phrase and answers in the gap. • Dynamics & EQ — Compressor, Limiter, Noise Gate, De-esser, a musical 5-band EQ and a 12-band graphic EQ, each with eight one-tap starting points you can overwrite with your own. Compressor, gate, de-esser and limiter show how much they are holding, in dB. • Vocal — Voice, a whole vocal channel behind one knob: low cut, gate, de-esser, compressor and sheen, all in the right measure; and the Doubler, which simulates two or four voices singing along. • Filter — an Auto-Wah that breathes with your playing, always first in the chain. BUILT FOR PLAYING Full MIDI Learn maps any hardware knob to any control, including the from–to range for an expression pedal. Tempo sync from your host keeps delay and modulation in time. Colour-coded scenes A–F, a preset library with favourites, and factory presets to get started fast. A tactile "pro hardware" interface, native on iPhone, iPad and Mac.

EverSpace is an algorithmic reverb designed for creating enormous spaces, evolving ambience and richly modulated echoes. Built upon the CloudSeed engine by Ghost Note Audio, its architecture draws inspiration from the algorithmic studio reverbs of the 1980s, where networks of delays and diffusion were used to create spaces that extended far beyond the limits of the physical world. Rather than attempting to recreate a particular room, hall or vintage hardware unit, EverSpace embraces the more creative possibilities of algorithmic reverb. Dense diffusion, multiple delay stages and extensive modulation allow sounds to bloom into vast, constantly moving environments — from spacious reflections and drifting echoes to seemingly endless atmospheric tails. At more extreme settings, EverSpace becomes much more than a conventional reverb. Simple sounds can be transformed into thick evolving pads, shimmering textures and expansive ambient soundscapes, with subtle variations within the reverb network ensuring that the resulting space remains alive and in motion. EverSpace can be used as a traditional send or insert effect, but it is at its best when treated as a creative sound-design tool where the reverb itself becomes part of the sound. Features ○ CloudSeed algorithmic reverb engine — a sophisticated multi-stage architecture inspired by classic algorithmic studio reverbs. ○ Early reflection and diffusion network — control density, delay, modulation and feedback to shape the initial character of the space. ○ Extensive late-reverb section — create everything from diffuse ambience to enormous, slowly evolving reverb tails. ○ Deep modulation — independently shape the movement of diffusion and delay stages for lush, animated spaces. ○ Multi-tap delay stage — adds rhythmic reflections, echoes and additional complexity before the main reverb network. ○ Integrated equalisation — low and high frequency shaping plus filtering to sculpt the colour and decay of the reverb. ○ Seed controls — regenerate the internal delay and diffusion structures to produce different variations from the same settings. ○ Interpolation modes — alter the behaviour and character of the internal delay network. ○ Real-time visualisation — waveform and frequency displays provide visual feedback as sounds enter and evolve through EverSpace.
