SKIIID is a percussion synthesizer built for real-time performance. Four pads. Each one is a sound sculpted by where your finger lands. Move left or right to morph between synth parameters. Move up or down to control velocity. Simple to play, deep to explore. — PADS — Four independent drum voices. Each pad morphs between parameter extremes based on X-axis position. Velocity is Y-axis. — STEP SEQUENCER — 16-step sequencer per pad. Variable step length for polyrhythms. Reverse playback, shuffle, pin and random step modes. Sync to Ableton Link or run free. — AUTO-MUTATE — Evolves your sound automatically. Individual interval and intensity per pad, synced to tempo. — CHAOS ENGINE — RANDOM, CHAOS, and MUTATE modes generate new sounds instantly. — AUv3 PLUGIN — Run SKIIID inside AUM, ApeMatrix, Audiobus, or any AUv3 host. Multiple instances work independently — different patches, different sequencers, no shared state. — MIDI — MIDI In for pad triggering. MIDI Learn for external controller mapping. Ableton Link for tempo sync. — WORKS ON — iPhone and iPad, all modern screen sizes. Landscape mode.

Evil Otto is a multiband OTT (Over-The-Top) compressor that applies simultaneous upward and downward compression across three frequency bands. The result is dense, hyper-detailed audio where peaks are controlled and quiet details are pushed forward — a sound heard across modern electronic music, pop, and hip-hop production. Features -- Three-Band OTT Compression Evil Otto splits your signal into low, mid, and high frequency bands and applies independent upward and downward compression to each. Quiet details come up, peaks come down, and each band can be tuned separately. -- Precise Control Without Complexity Fifteen parameters give you everything you need and nothing you don't: Depth, Time, independent Down and Up amounts, per-band thresholds, per-band output levels, and input/output gain. -- Sidechain Input Route an external signal to duck the compressed output for rhythmic pumping effects. A dedicated Listen mode lets you monitor the sidechain signal to verify routing. -- Real-Time Metering Nine meters show input levels, gain reduction, and output levels per band. The center meters display both downward compression and upward expansion relative to the threshold, so you can see exactly what the compressor is doing. -- Factory Presets Includes a library of starting points across a range of applications. Save and recall your own presets with the built-in preset browser. -- Cross-Platform Compatible User presets created on iOS work on macOS, Windows, and Linux. Sessions created in GarageBand or Logic on iOS will open the desktop version on macOS.
