SKIIID v1.5 by Stephan Bolch

The v1.5 overhaul transforms workflow. Each AUv3 instance now carries its own sound, sequencer, and presets with zero shared state. The sequencer gains shuffle, reverse playback, variable step length per pad for polyrhythms, plus pin and random modes. Auto-Mutate evolves every pad independently with tempo-synced interval and intensity controls, while MIDI In and MIDI Learn let external controllers trigger pads and map parameters. Ableton Link sync now runs flawlessly and the randomizer works without limits.

SKIIID remains a real-time percussion synthesizer built for expressive finger performance. Four independent pads respond to X-axis finger position for morphing between synth parameters and Y-axis for velocity, turning every tap into dynamic, musical hits. The chaos engine delivers instant RANDOM, CHAOS, or MUTATE variations that spark new ideas in seconds.

The app balances simplicity and depth perfectly. Producers love the immediate playability and the way Auto-Mutate keeps patterns alive without constant tweaking. It works smoothly as an AUv3 plugin inside AUM, letting you layer multiple SKIIID instances with completely different sequencers and sounds in a single project.
