Oscidia is an AUv3 plugin for iOS which can be loaded into your favorite DAW allowing you to use it as a sound source for any MIDI source. Its wide range of features and oscillator types allow it to produce a vast variety of sounds. In particular, the inclusion of WaveTable greatly expands the traditional wave types and brings a wealth of modulation options. Oscidia has 3 oscillators per voice, and each oscillator can be a different wavetable – all working and morphing together to create some incredibly amazing sounds. Oscidia includes SINE, SAW, SQUARE, TRIANGLE, SUPERSAW, SUPERSQUARE, WAVETABLE and ADDITIVE wave types. You can import and export compatible wavetables using drag and drop directly to the WaveTable manager. Wavetables support morphing and warping (phase distortion), all controlled by the Mod Matrix routing. The SINE and TRIANGLE wave types both support several wave folding modes which allow dramatic real-time morphing too. Oscidia also supports 5 filter types which support 12/24dB modes and morphable LP/BP/HP filter modes which can be automated from the Mod Matrix or via the Sequencer. The sequencer itself is very unique and allows up to 3 simultaneous ARPs to play at the same time. Each ARP can directly control the 3 oscillator levels independently per step, as well as the pitch, filter morph, cutoff frequency, probability, gate, note repeat and ties. This allows for some really complex rhythms to be created that are not tied to pitch. Oscidia Features: • 3 Oscillators Per Voice. • Support for Wavetable and Additive synthesis. • WaveTable supports Morph and Warp (Phase Distortion) features. • 4 LFOs Per Voice. • 5 Filter types with 12/24-bit slopes and morphable LP/BP/HP. • 4 ADSR (Attack, Decay, Sustain, Release ) or FEG (Fluid Envelope Generators). • Wave Folding is available for basic waveforms such as SINE and TRIANGLE. • OSC Sync. • XMod & Ring Mod (on osc1 & osc2). • Additive Synthesis for glass, metallic and bell like tones. • Build in Sequencer (with 3 independent ARPs). • Mod Matrix. • MPE Mode. • Internal Effects - reverb, delay, chorus, Haas, and Phaser effects. • Drag and Drop for import and export presets and wavetables. • Build in Help Manual.

Ascent is a dual reverb for iPhone and iPad. It pairs a deep, natural hall reverb with a granular pitch-shifting particle engine: two reverbs, one interface, built to work together. The result is a sound that moves, from grounded, room-filling depth to shimmering, pitch-shifted atmospheres that evolve over time. The hall is the foundation; it always runs. The particle engine sits on top, and BLOOM sets how much of it you hear. Pull Bloom to zero for a pure hall, push it up for shimmer over the space, and dial in the built-in ducking compressor to keep your dry signal present. Subtle space to full cinematic wash, without ever touching a second effect. FEATURES • Dual reverb engine: hall reverb and particle reverb run simultaneously, with Bloom controlling the amount of shimmer. • Granular particle engine: pitch transposition from -12 to +12 semitones. Dual overlapping grains eliminate the metallic artifacts common in lesser shimmer reverbs, and an octave down gives darker, sub-octave shimmer just as easily as pitching up. • Expanse control: three tuned room modes (Small, Medium, Large) shape the delay network and spatial character of the hall, not just the decay time. • Particulate: adds a touch of randomness to grain pitches for thicker, more organic texture. • Built-in dynamic ducking: reverb tails pull back on transients automatically, keeping your dry signal present without constant fader riding. • Full preset manager with factory presets and favorites. • Runs as an AUv3 plugin in your favorite host, plus a standalone app. Ascent is part of Audio Damage's Motion Effects family, alongside Descent and Traverse. No accounts, no subscriptions, no in-app purchases. Buy it once and it is yours.
