Overview
From pitch movement to musical context
Chronos shows pitch as continuous motion, live, as you play.
You see vibrato, bends, slides, and stability unfold over time, so practice becomes awareness, not correction.
That same view extends into musical context and serious practice tools:
- •Practice inside real musical systems instead of abstract pitch
- •Switch freely between voice, instruments, and controllers
- •Save moments when something clicks and revisit them later
