Detailed Description

V/Oct pitch CV input with smoothing and calibration.

Owns a CvInput for EWMA smoothing and stores calibration state. Hardware-agnostic — takes raw ADC values, no driver calls.

V/Oct pitch CV input with smoothing, calibration, and pitch conversion

Note

All public methods are ISR-safe — pure state machine with no hardware I/O.
