Monstrous is a powerful instrument designed to deliver rich and immersive soundscapes through its 3-layer architecture, each layer featuring dedicated amplitude envelope controls, detune, pan settings, and a MIDI channel selector. It offers advanced filtering with three filters equipped with envelope shaping, allowing for dynamic tonal adjustments. The instrument includes two send effects—chorus and delay—and a unique Preverb effect that functions both as a reverb and as a send effect, enhancing spatial depth and texture.

The expansive 2.0GB sound library encompasses a wide range of sounds including atmospheres, textures, vocals, keys, organs, brass, strings, basses, plucked instruments, percussion, and sound effects. These sounds are particularly suited for creating atmospheric and cinematic music, ideal for science fiction, horror, and moody settings, as well as for experimental and creative musical projects. The library's diversity supports a broad spectrum of genres and moods, providing users with a comprehensive toolkit for sound design.

Monstrous also features two master effects—a smooth reverb and a tempo-synced delay—designed to polish and enrich the overall mix. Additional functionality includes MIDI automation compatibility, allowing seamless integration with control surfaces for dynamic performance control, and velocity response for expressive playing. This instrument combines extensive sound shaping capabilities with a robust sound collection, making it a serious choice for musicians and producers seeking to craft compelling and immersive audio experiences.
