Filthpig is a powerful hybrid synthesizer designed for creating rich drones, noise textures, sirens, and glitch sounds. It features six oscillators divided into two sections, each with three oscillators, where one section generates the primary sound while the other acts as a dedicated modulation source. Each oscillator offers five waveform options, individual tuning controls, amplitude envelopes, and modulation depth settings, allowing extensive sound design possibilities.

The synthesizer includes a sophisticated modulation matrix that enables any oscillator to modulate itself or others, providing complex and evolving sonic textures. This matrix also supports oscillator sync, enhancing the harmonic interaction between oscillators. The modulator section links oscillator output to pitch control in the sound-producing section, expanding the modulation capabilities for dynamic sound shaping.

While primarily a monosynth, Filthpig offers a three-voice polyphonic mode for added flexibility in performance and composition. Its dual cascaded filters, including a high-cut and a low-cut filter, provide advanced tone shaping options to refine the output. This combination of extensive modulation, polyphony, and filtering makes Filthpig a highly expressive tool for experimental and electronic music production.
