We present MuSA.RT, Opus 1, a multimodal interactive system for music analysis and visualization using the Spiral Array model. Real-time MIDI input from a live performance is processed, analyzed and mapped to the 3D model, revealing tonal structures such as pitches, chords and keys. A user can concurrently navigate through the Spiral Array space using a gamepad or set the camera control to automatic pilot. The interaction among and concurrent processing of the different data streams is made possible through the Modular Flow Scheduling Middleware.
