Fathom Synth is a modular software synthesizer designed for innovative sound creation and detailed waveform manipulation. It offers a fully modular signal flow, allowing users to craft unique sounds through original waveform development and advanced wave table processing. The synth features multiple oscillators, including alias-free basic waveforms, analog saw, additive spectrum, and wave draw capabilities, enabling a wide range of sonic possibilities. Its extensive modulation options support complex and accurate modulations, with an advanced matrix that permits unlimited modulations per dial and dials per modulation.

At the heart of Fathom is its wave table morphing oscillator, which allows real-time morphing between two tables of 16 waveforms each, creating a dynamic 3D wave space. Users can modulate wave indexes and apply various algorithms such as morph, add, subtract, and pulse width to shape sound textures creatively. The synthesizer supports freehand wave drawing, Bezier and exponential curve shaping, and compatibility with Serum wave table import and export. With over 500 factory presets, 250 waveforms, 100 wave tables, and rich effects including chorus, reverb, phaser, and delay, Fathom provides a comprehensive toolkit for sound designers.

Fathom Synth also delivers high polyphony of 32 voices and user-defined microtuning with file support, enhancing its musical flexibility. Its interface is resizable with multiple themes, making it accessible and visually adaptable. The synthesizer is compatible with both Windows and Mac, offering extensive control over buffer sizes and interpolation algorithms for optimized performance. With frequency-ranged noise generation, harmonic and random distortion, and host automation for nearly every control, Fathom stands out as a powerful instrument for producers seeking deep sound design capabilities combined with an intuitive workflow.
