Augmatic GRE vs tapeworm
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
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.
- 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.
tapeworm
This music app offers a unique tape delay effect with a "wiggly, dirty" sound. Control delay time by stretching or flicking a virtual tapeworm, with options for manual or random adjustments. It includes analog-modeled saturation, compression, and amplifier stages for a rich audio experience.
- Interactive tape delay time control
- Manual and free modes for delay
- Analog-modeled tape saturation and compression
- Overdrivable feedback
- AUv3 plugin compatibility
- Performative sound design elements

Tapeworm is a tape echo with a unique method of changing the delay time, and a wiggly, dirty sound. You can set the delay time manually by stretching the worm. The record button will flash to show the current interval. You can exit the fixed time mode and enter free mode by toggling. This lets the delay time change randomly, which you can encourage by flicking the tapeworm around. Double tap to reset, adding a fun performative element to your sound. Feedback can be overdriven. An analog-modeled tape saturation and compression, and amplifier and limiter stage, keep it sounding juicy when it gets loud. Tapeworm is audio unit (AUv3) compatible, meaning you can use it as a plugin in your app of choice like AUM, GarageBand or Logic. We hope you enjoy using tapeworm for music, or just for fun.
