Siren makes playable instruments from words and provides ADSR controls and low-pass, high-pass, band-pass, and notch filters. DrumGPT creates 16-element drum kits from text prompts, with pitch, volume, and amplitude-envelope controls. The Stems Plugin works with major DAWs and other software that supports VST3, with Windows VST3 and Mac VST3/AU support. Siren is available online, as an iPhone and iPad app, and as an audio plugin. The API separates songs into vocals, drums, bass, melodies, and instrumental, and detects MIDI, chords, key, and tempo. API use requires Fadr Plus; its Create Stem Task endpoint costs US$0.05 per minute of audio.
