ThermoSynth vs Tone Workshop
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.

Verdict
The clearest difference is price: Tone Workshop at Free against ThermoSynth's $34.99. Tone Workshop also leads on device support (4 vs 1). ThermoSynth's advantage is in-app purchases (none vs 4) and iOS requirement (9.3 vs 13.0). On update cadence and ads there is nothing between them.
