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. ## Key features - Four morphing percussion pads - Real-time parameter control via touch - 16-step sequencer per pad - Auto-mutate sound evolution - Chaos engine for instant sound generation - AUv3 plugin support - MIDI input and Ableton Link sync ## Recent user reviews (10 of 23) All indexed reviews: https://appshunter.io/ios/app/skiiid/id1516634571/reviews.md ### 1/5 — Really sucks. *2026-02-18* It’s just a bunch of static and glitchy sounds. Nothing really musical. I wasted my money. ### 5/5 — Love it! *2026-02-10* Buy it! ### 1/5 — No real MIDI implementation in standalone mode. *2024-12-15* It must be profoundly challenging to implement MIDI in iOS apps. ### 5/5 — It’s own thing *2023-07-16* The sound palette and rhythmic structures this thing can produce are stunning. Teams up nicely with Octachron. Oscillator crackles when the pitch is changed. Hope this can be fixed. ### 5/5 — This was great! Easy five stars! Needs an update nowadays! *2022-12-21* Love this app but hadn’t used it in a bit. Just opened it up and it definitely needs an update. Do an IAP! I’d purchase in a heartbeat. This was cool in the first place! Recent updates make it awesome! Nice combination of random and programmed sounds! 😎👍🏼👍🏼 ### 1/5 — Wastes 20% of iPhone 12 display *2022-12-10* Making it impossible to see and play. ### 4/5 — app was the best until iOS 16 *2022-12-03* the app has multiple modes, and you can easily bounce between the three and really utilize this app by itself as a peformance level drum synth. unless you upgrade to an iphone 13 from iphone 11 and are using iOS 16. once that happens you lose the ability to leave the first mode, rendering the drone and sequencer as well as all of their features unusable. this is a bummer. i will go back to five stars if they update and fix this issue. ### 3/5 — Sound great *2021-12-04* Sounds great but midi implementation is not good. No midi cc. No way to change midi channel. No way to change midi notes. And you can’t trigger more than one sound at a time even if you load 2 instances in AUM. ### 5/5 — Favorite iOS percussion synth *2021-06-20* So innovative and weird but still easy to dial in to taste. Please make more apps! ### 5/5 — Great for experimental music! *2021-03-04, version 1.18* This is just what I was looking for, amazing, thanks!!! ## Frequently asked questions about SKIIID ### What is SKIIID? SKIIID is a percussion synthesizer designed for real-time performance. It offers four independent drum voices, each controlled by morphing pads where your finger position sculpts the sound parameters and velocity. It also includes a step sequencer, auto-mutation features, and a chaos engine for creative sound exploration. ### How does the morphing pad system work? Each of the four pads is a sound sculpted by where your finger lands. Moving your finger left or right morphs between synth parameter extremes, while moving up or down controls the velocity of the sound. This allows for intuitive and dynamic sound manipulation during performance. ### What are the sequencing capabilities? SKIIID features a 16-step sequencer for each pad, offering variable step lengths for polyrhythms. It includes modes like reverse playback, shuffle, pin, and random step options. The sequencer can sync to Ableton Link or run independently. ### Can I use SKIIID with other music apps? Yes, SKIIID supports AUv3 plugin hosting, allowing you to run it within applications like AUM, ApeMatrix, and Audiobus. It also supports MIDI input for pad triggering and external controller mapping, as well as Ableton Link for tempo synchronization with other devices and apps. ### What devices is SKIIID compatible with? SKIIID is compatible with both iPhone and iPad, supporting all modern screen sizes. It is designed to work in landscape mode for an optimal user experience during music creation and performance. ## Version history (last 5 releases) ### 1.5.4 — 2026-04-10 • Fixed MIDI Learn — CC mapping now works correctly with hardware controllers in standalone mode • Fixed sequencer OPTIONS popup — step count, direction, and shuffle changes now take effect immediately • Fixed AUv3 MIDI input — MIDI notes now correctly trigger pads in the Audio Unit plugin. • AUv3 layout overhaul — Redesigned the Audio Unit layout to look sharp and consistent across all iPads and iPhones.
