Cycle combines wave-draw and spectral synthesis techniques to create unique sounds by processing audio in single-cycle units based on user-drawn waveforms. It analyzes each cycle's spectral content in real time, generating harmonic and phase spectra that can be independently shaped using spectral curves. The synthesis approach centers on geometric wave-shapes and spectral curves with multiple morphing states, enabling dynamic sound evolution through smooth transitions between different curve forms.

The instrument provides a comprehensive, CAD-style interface for creating and editing waveform geometry and spectral data all on a single page. Its robust workflow tools include freehand drawing, curve fitting, selection options, and undo functionality, supported by real-time visual feedback of waveform and spectral changes. This design aids sound modeling by making the impact of edits immediately clear. Cycle also supports importing audio samples to analyze their spectral qualities, enhancing sound design without resynthesis limitations.

Featuring meticulously crafted audio-specific curve design, Cycle offers smooth and flexible control over wave-shapes, envelopes, and effects such as a programmable waveshaper and impulse response convolution. The plugin delivers true stereo sound with multi-layered mesh geometry and includes tools like unison voices, delay, reverb, and EQ. With over 160 factory presets and an integrated browser for searching and sharing, it provides a powerful environment for innovative sound creation.
