- Algorithmic and Euclidean rhythm generation
- Morphable Grids Engine for evolving beats
- Blend control between pattern types
- Linear drumming for articulate patterns
- Velocity bender for expressive dynamics
- Groove tools for swing and timing

MAIN FEATURES: - 6 Algorithmic Channels - Bass drum, snare, hi-hat, plus accents which create complementary rhythms, not duplicates. Each channel can generate its own rhythmic voice for rich, layered drum patterns. - Topographic Engine - Morphable, evolving beats based on the Mutable Instruments Eurorack module. Navigate an X/Y map of interconnected drum patterns extracted from actual drum loops with smooth interpolation between patterns. - Euclidean Engine - generate evenly distributed, world‑inspired rhythm patterns using Euclidean algorithms. Configure steps, hits, and start position independently on each channel for precise control. - Blend Control - Crossfade between Grids and Euclidean patterns to introduce variation while preserving the core character of your groove. - Linear Drumming - Control which drums play together or play alone. Eeach sound has room to breathe. Creates clean, articulate patterns. Used in Hip-Hop, IDM, Funk, Fusion. - Velocity Bender - Shape velocity dynamics for a more expressive, dynamic pulse. Create ghost notes, and rhythmic emphasis that bring patterns to life. - Groove Tools - Swing, humanization, clock division, and timing shift. Fine-tune the feel of your patterns from tight and mechanical to loose and human. IMPORTANT: This app does not produce sound on its own. It generates MIDI notes and requires a drum sampler or synthesizer to play them.
