Abstractor is a comprehensive additive synthesizer offering a wide range of sound design capabilities. It combines additive synthesis with frequency modulation (FM) and amplitude modulation (AM) to create rich and dynamic tones. The synthesizer supports importing single cycle waveforms, allowing users to customize and expand their sonic palette with unique textures.

The interface features an intuitive XY pad that enables real-time modulation and expressive control over sound parameters. Abstractor also includes a two-step sequencer for creating rhythmic patterns and evolving sequences. Its FFT-based wave generator, which incorporates a low-frequency oscillator (LFO), adds depth and movement to the generated sounds.

With an analog-style filter and a selection of 110 presets, Abstractor provides both classic and modern tones suitable for a variety of musical styles. This free synthesizer is designed for musicians and producers seeking a powerful tool to explore additive synthesis without complexity.
