4Pockets Auto Tuner is real-time chromatic instrument tuner for your PC and 838 Pro. The tuner can accurately determine the frequency, musical note and octave of any input signal without the need to pre-select target notes or strings.

Auto Tuner automatically calculates the nearest musical note to that being played on your instrument and accurately determines how many cents the note is away from the true frequency. Simply tune your instruments so that the actual frequency of the note being played matches that of the true calculated target frequency. This allows you to easily experiment with different tunings as it eliminates the need to pre-select note frequencies.

The program incorporates harmonic error correction technology and the ability to compensate for notes played in wrong octave, allowing you to tune using either open strings or harmonics.
