What the reviews say: "A must-have drum synth for electronic music lovers on iOS" - Keyboard Mag "All of this comes together in a vision that’s really playable [...] this is another excellent choice for the iPad." - CreateDigitalMusic "Small, compact and easy to use, Ruismaker is both inexpensive and a perfectly credible choice if you are after solid drum synth sounds." - MusicAppBlog -- Ruismaker is a unique drumsynth plugin (i.e. it does not use samples), which is coupled with a creative Euclidean sequencer when run in standalone mode. The plugin is fully AUv3 (Audio Unit) compatible: - Seamless integration with Garageband and other AU hosts - Audio Unit Instrument: making music on iOS doesn't get more convenient - Supports Multi-Output AUv3 in AUM and ApeMatrix! - Each sound is modeled using authentic analog and FM algorithms; - Comes with dozens of unique customizable models - Does not use any samples; all sounds are synthesized in realtime, on the fly - Emulates analog components, introducing subtle, natural fluctuations in the sound - Light on the CPU, so you can run lots of Ruismakers simultaneously - Fully automatable parameters (requires host support) and MIDI CC controllable - Has its own preset manager The standalone sequencer is refreshingly different: - Program patterns using Euclidean algorithms - Powerful random feature and mutation probability settings per channel - Syncs with Ableton Link or MIDI Clock - Exports WAV and MIDI - Compatible with Audiobus 3 (including MIDI IN/OUT mode) - CoreMIDI In and Out - AU MIDI output for the on-screen pads User manual available on Ruismaker.com

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.

Ruismaker's advantage is rating (4.8 vs 4.4) and iOS requirement (11.0 vs 16.0). On review sentiment, ratings volume, ads and in-app purchases there is nothing between them.
