Synthractive is a stereo subtractive synthesizer designed to shape sounds by filtering out unwanted frequencies and harmonics. Users can sculpt a broad range of sonic textures by adjusting parameters from oscillators, low-frequency oscillators (LFOs), amplitude, and filter envelopes. This approach allows for precise control over the tonal character and dynamic shaping of each sound, making it suitable for creative sound design.

This synthesizer excels at producing a wide variety of sounds, including spacey pads, synth leads, basses, keys, sequences, atmospheric textures, ambient soundscapes, and unique sound effects. It offers 40 presets that cover many musical genres and styles while providing the flexibility to custom design sounds across an extensive sonic palette. The built-in preset manager makes browsing, loading, and saving sounds effortless.

Synthractive features two oscillators with multiple waveform options, fine-tuning, pulse width, and level controls. The state-variable filter provides lowpass, highpass, bandpass, and band-rejection modes with adjustable cutoff, resonance, keyboard tracking, and a dedicated envelope. Two LFOs with selectable waveforms offer modulation options for pitch, filter cutoff, pulse width, and volume, adding movement and expression. Additional effects like stereo reverb and delay enhance spatial depth and stereo imaging, making it a powerful tool for both studio production and live performance.
