Osiris by Libre Wave is a sample library that captures the essence of the simsimiyya, a traditional Egyptian lyre. This instrument is deeply rooted in the religious and cultural traditions of Egypt, particularly the Sinai Peninsula, and is known for creating a hypnotic, trance-like atmosphere.

Osiris provides a comprehensive set of features for authentic and expressive performances:

• Articulations: Includes plucked and picked sample sets, tremolo, ebow drone recordings, and percussive hits. Additional articulations combine these samples for rich and varied tones.
• Round Robins and Dynamics: The plucked articulation offers twelve round robin repetitions per note, while the picked articulation includes six, with samples recorded at three dynamic levels triggered by MIDI velocity.
• Maqams: Features playable maqams (Middle Eastern scales) with key-switches or an on-screen dial to switch between pre-programmed maqams. The on-screen keyboard updates to show playable notes and those that play a quarter tone lower.
• Real-time Control: Dedicated retrigger key-switch for playing double notes or tremolo in real-time, and pitch bend variations triggered by high MIDI velocity.
• Interface: Provides standard velocity curve and ADSR envelope controls for detailed sound shaping.

Osiris is designed to integrate seamlessly with contemporary music production while preserving the rich cultural heritage of the simsimiyya, making it a valuable tool for composers and producers seeking authentic Middle Eastern sounds.
