This foundation ensures rich, realistic bass tones with expressive features such as multisampled dynamic slides and extensive round-robin sampling for natural repetition.

Featuring a modern user interface, Trilian introduces innovative tools like an arpeggiator with Groove Lock to synchronize bass lines effortlessly with grooves or MIDI files. The instrument supports eight-part multi-timbrality, allowing multiple articulations to be accessed simultaneously, while Live Mode provides instant key-switching between dynamic bass articulations. The new Custom Controls page simplifies rapid editing and customization of patches, and the integrated effects rack includes all effects from the flagship Omnisphere synthesizer for enhanced sound design possibilities.

Trilian also offers full library integration with Omnisphere, enabling users to utilize Trilian’s bass sounds within Omnisphere's expansive environment. The powerful new browser facilitates quick searching through sounds with attributes, tags, and images, while the Edit Page delivers advanced manipulation capabilities such as timbre shifting, FM synthesis, flexible modulation, and dual-voice harmonies.
