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.
