ThermoSynth vs LoopMangler
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
ThermoSynth
This app is a generative synthesizer that creates evolving sonic structures inspired by thermodynamic systems. It features a self-regulating hyper oscillator engine with a feedback matrix and stochastic modulators for unique, never-repeating drone synthesis and organic textures.
- Self-regulating hyper oscillator engine
- Generative synthesis at waveform level
- 4x4 feedback matrix for oscillator interaction
- Stochastic modulators for sonic changes
- User-controlled injections for system perturbation
- MPE support
- High-resolution rotary encoder MIDI mapping

Welcome to the politics of sound ! ThermoSynth is a self regulating hyper oscillator engine inspired by thermodynamic systems. ThermoSynth extends the classical oscillator concept, it is a generative synthesizer at the waveform level, which does not express only static / interference waveforms but also an evolution of a sonic structure by internal communication and its actions inside certain controllable margins. The oscillator of ThermoSynth establishes its own engine environment and begin its signal path with a waveform generator ( pure mathematical, not samples nor optimized tables ) rendering basic waveforms and capable of morphing in between. The 4 oscillators of the Thermo are in continuous interaction sending each other their signals thanks to a 4X4 feedback matrix. Many type of changes in this system are introduced by the stochastic modulators which sonicLAB is known for and also by the user through some perturbations called the injections into the system. Each oscillator engine continuously checks its environment conditions and takes decisions, “self regulates”, in reaction to these changes applied. The result is unique never ending and never repeating drone synthesis, pure organic textures for electronic music; and hours can easily pass with experimenting on ThermoSynth. Detailed app description can be found at https://www.sonic-lab.com/thermo/ And you can download the manual here : https://www.sonic-lab.com/Thermo/Thermo-iOS_manual.pdf ThermoSynth is identical to the desktop sonicLAB Thermo version. For external control, it comes with MPE support and sonicLAB high resolution rotary encoder midi mapping feature as on the desktop version.

LoopMangler is an innovative multi-effect glitch sequencer designed to manipulate rhythmic samples, external input, or output from other applications. This powerful tool operates based on the effect sequence patterns, allowing you to transform ordinary loops into unusual glitchy and noisy textures. Key Features: Advanced Sound Design: With its well-designed user interface and creative features, LoopMangler provides an exciting playground for sonic exploration and sound design. Random Pattern Generation: Make patterns and individual bars randomly or according to specific rules, offering a quick start or a source of inspiration for your projects. Multi-Effect Sequencing: Assign up to six distortion and filter effects to each step of the sequencer, providing endless possibilities for sound manipulation. Envelope Modulation: Each effect is modulated with its own envelope generator, ensuring that every step is unique and dynamic. Intuitive Editor: The user-friendly editor allows you to easily copy, move, and delete individual cells and bars within the sequencer, making pattern creation a breeze. Live Pads: Assign presets and loops to on-screen pads and use special pads to dynamically alter sound patterns during live performances or studio sessions. Real-Time Processing: Process audio in real-time, allowing you to hear the effects of your adjustments immediately. Flexible Integration: Seamlessly integrates with other audio applications, making it a versatile addition to your music production toolkit. Whether you’re looking to add subtle textures or completely transform your audio, LoopMangler provides the tools you need to achieve your sonic vision. LoopMangler is a universal application for iOS and macOS. It can work on iPhone and iPad as well as Mac / MacBook with M1 chip (and later). LoopMangler works on iPhone and iPad standalone, as an Audio Unit or Inter-App Audio module, and supports Audiobus and Ableton Link. On MacOS, LoopMangler can works both as a standalone application and as an Audio unit (AUv3) with DAWs and other hosts that support AUv3 plugins. LoopMangler has a built-in detailed description of all parameters also available as PDF file on the application site.
