The scrooo is a polyphonic software synthesizer designed for both Windows and macOS platforms, supporting multiple plugin formats including VST2, VST3, CLAP, and AU. Developed with native C++ code, it delivers high performance and efficient processing, making it suitable for complex sound design and music production tasks. Its architecture is based on spectral formant synthesis, allowing users to explore unique timbres and textures that go beyond traditional subtractive synthesis.

This synthesizer offers up to 64 voices of polyphony, including a Unison mode and portamento for smooth pitch transitions. It features two band-limited carrier oscillators alongside three fully independent formant generator sections, each with three different formant generation modes. These components work together to create rich, dynamic sounds that can be shaped extensively. The instrument also includes three envelopes with exponential slopes and three tempo-synchronized low-frequency oscillators, providing detailed modulation capabilities.

Additional controls include two amplifiers with volume and panorama settings, offering precise stereo image shaping. The plugin supports MTS-ESP dynamic micro-tuning, expanding its expressive potential by enabling microtonal adjustments. All parameters can be controlled via MIDI CC through its comprehensive MIDI Learn feature, allowing seamless integration into any MIDI setup. Compatible with both 32-bit and 64-bit systems, the scrooo is a powerful tool for producers seeking innovative sound synthesis.
