Chronos
Real-time pitch detector and visualizer for musicians.
See pitch motion over time, not just a tuner reading. Chronos turns voice, instruments, MIDI, and MPE input into live pitch curves for intonation practice, microtonal scales, and focused listening.

Overview
From pitch detection to musical context
Chronos starts as a real-time pitch detector, but the value is the visual history.
You see vibrato, bends, slides, and stability unfold over time, so practice becomes awareness, not correction.
That same pitch-tracking view extends into musical context and serious practice tools:
- •Practice inside real musical systems instead of abstract tuner feedback
- •Switch freely between voice, instruments, MIDI, and MPE controllers
- •Save moments when something clicks and revisit them later
