About

Augmatic GRE

Generate complex and evolving drum patterns using algorithmic and Euclidean engines. This app creates MIDI notes that require a separate sound source to produce audio, offering deep control over rhythm and dynamics.

Highlights
  • 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.

Evil Otto is a multiband OTT (Over-The-Top) compressor that applies simultaneous upward and downward compression across three frequency bands. The result is dense, hyper-detailed audio where peaks are controlled and quiet details are pushed forward — a sound heard across modern electronic music, pop, and hip-hop production. Features -- Three-Band OTT Compression Evil Otto splits your signal into low, mid, and high frequency bands and applies independent upward and downward compression to each. Quiet details come up, peaks come down, and each band can be tuned separately. -- Precise Control Without Complexity Fifteen parameters give you everything you need and nothing you don't: Depth, Time, independent Down and Up amounts, per-band thresholds, per-band output levels, and input/output gain. -- Sidechain Input Route an external signal to duck the compressed output for rhythmic pumping effects. A dedicated Listen mode lets you monitor the sidechain signal to verify routing. -- Real-Time Metering Nine meters show input levels, gain reduction, and output levels per band. The center meters display both downward compression and upward expansion relative to the threshold, so you can see exactly what the compressor is doing. -- Factory Presets Includes a library of starting points across a range of applications. Save and recall your own presets with the built-in preset browser. -- Cross-Platform Compatible User presets created on iOS work on macOS, Windows, and Linux. Sessions created in GarageBand or Logic on iOS will open the desktop version on macOS.
