ThermoSynth vs Oscidia
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.
Oscidia
This powerful synthesizer app allows iOS users to create a vast array of sounds using multiple oscillators, wavetable synthesis, and advanced modulation options. It features a versatile sequencer with independent arpeggiators and built-in effects for complex sound design.
- 3 Oscillators Per Voice
- Wavetable & Additive Synthesis
- Morphing & Warping Wavetables
- 5 Morphable Filter Types
- 3 Independent Arpeggiators
- Mod Matrix
- Internal Effects Suite

Oscidia is an AUv3 plugin for iOS which can be loaded into your favorite DAW allowing you to use it as a sound source for any MIDI source. Its wide range of features and oscillator types allow it to produce a vast variety of sounds. In particular, the inclusion of WaveTable greatly expands the traditional wave types and brings a wealth of modulation options. Oscidia has 3 oscillators per voice, and each oscillator can be a different wavetable – all working and morphing together to create some incredibly amazing sounds. Oscidia includes SINE, SAW, SQUARE, TRIANGLE, SUPERSAW, SUPERSQUARE, WAVETABLE and ADDITIVE wave types. You can import and export compatible wavetables using drag and drop directly to the WaveTable manager. Wavetables support morphing and warping (phase distortion), all controlled by the Mod Matrix routing. The SINE and TRIANGLE wave types both support several wave folding modes which allow dramatic real-time morphing too. Oscidia also supports 5 filter types which support 12/24dB modes and morphable LP/BP/HP filter modes which can be automated from the Mod Matrix or via the Sequencer. The sequencer itself is very unique and allows up to 3 simultaneous ARPs to play at the same time. Each ARP can directly control the 3 oscillator levels independently per step, as well as the pitch, filter morph, cutoff frequency, probability, gate, note repeat and ties. This allows for some really complex rhythms to be created that are not tied to pitch. Oscidia Features: • 3 Oscillators Per Voice. • Support for Wavetable and Additive synthesis. • WaveTable supports Morph and Warp (Phase Distortion) features. • 4 LFOs Per Voice. • 5 Filter types with 12/24-bit slopes and morphable LP/BP/HP. • 4 ADSR (Attack, Decay, Sustain, Release ) or FEG (Fluid Envelope Generators). • Wave Folding is available for basic waveforms such as SINE and TRIANGLE. • OSC Sync. • XMod & Ring Mod (on osc1 & osc2). • Additive Synthesis for glass, metallic and bell like tones. • Build in Sequencer (with 3 independent ARPs). • Mod Matrix. • MPE Mode. • Internal Effects - reverb, delay, chorus, Haas, and Phaser effects. • Drag and Drop for import and export presets and wavetables. • Build in Help Manual.

Verdict
The clearest difference is price: Oscidia at $14.99 against ThermoSynth's $34.99. Oscidia also leads on review sentiment (88% vs 50%) and device support (3 vs 1). ThermoSynth's advantage is iOS requirement (9.3 vs 13). On rating, update cadence, ads and in-app purchases there is nothing between them.
