Siren is a musical synth that allows you to create playable instruments with words. Just describe the sound you'd like and Siren gives you an unlimited stream of unique options to choose from. It is available online, as a mobile app (iPhone + iPad), and as an audio plugin (compatible with all major DAWs).
Siren has been reengineered inside and out. It features a brand new AI instrument generation engine that is capable of creating an infinite number of never-before-heard sounds. The level of quality, accuracy, and control the new engine provides is vastly improved over Siren 1. We've also implemented a plethora of new features based on your feedback. With Siren, you can use a powerful ADSR curve to control the amplitude envelope of the synth's output. Additionally, Siren features four high quality filters, a low-pass, high-pass, band-pass, and notch filter, all available in 12 or 24 db/oct configurations. All of these parameters and more are tightly integrating with your DAW, enabling powerful automation possibilities.
