Chronos - See pitch movement live for voice and MIDI

by•
Chronos shows pitch as a continuous curve in real time for voice and MIDI. Instead of snapping to note values like a traditional tuner, it visualizes full pitch movement over time. It supports per-note pitch tracking with MPE, works with custom tuning systems beyond standard equal temperament, and provides scale context with built-in Western and Arabic modes.

Maker here. I built Chronos because I wanted to see what I was actually playing and singing in real time, not just a tuner number. I sing and play MIDI, and I could not find a tool that lets me visualize both at the same time. Chronos draws pitch as a continuous curve and keeps a short rolling history. You can pause the display to freeze the plot and inspect what just happened and how stable a note was, how vibrato moved, or how a pitch approached a target. It supports MPE for per-note pitch tracking and works with alternative tuning systems beyond equal temperament. You can also import custom scales and use built-in Western and Arabic modes for scale context while practicing. For me, the shift was seeing pitch as motion instead of discrete notes. Curious how you would use something like this practice, performance, production, or microtonal work?
