Metronaut

Metronaut is an AI-powered accompaniment app that lets musicians play with world-class orchestral and piano backings that adapt to them in real time. It transforms any acoustic or MIDI instrument or voice into an interactive performance experience: the app follows the musician’s tempo and expression, aligns the audio with the score instantly, and produces a fully responsive accompaniment. This creates a uniquely engaging live demo format — one performer, a device, and a full orchestra reacting musically to their playing. It’s accessible, visually compelling, and speaks directly to how modern musicians use technology. (Demo video of our MIDI feature: https://youtu.be/Tw15poOkDpc )

Behind this simplicity is a deep stack of AI algorithms capable of interpreting the score, aligning real musical performances with symbolic notation, and extracting expressive parameters that drive our orchestral synthesis engine. This makes Metronaut an ideal early adopter and demonstrator for MIDI-CI Profiles for Orchestral Articulation: our internal models can already generate articulation-aware orchestral accompaniments, and MIDI-CI gives us a standardized way to express and exchange that musical intent. We can showcase, in a live setting, how intelligent performance analysis and standardized articulation semantics combine to produce expressive, portable orchestral results — exactly the type of forward-looking, musician-centric use case that embodies the promise of MIDI 2.0.
