Korg At2 Top

Allows for quick, accurate tuning of acoustic instruments without requiring a cable.

The AT-2 uses a digital signal processor (DSP) to analyze the incoming waveform from either the built-in microphone or direct input. It performs Fast Fourier Transform (FFT) to identify the fundamental frequency, compares it to the nearest equal-tempered note, and displays the deviation in cents. The “auto” mode eliminates the need to select an instrument or note. korg at2 top
