Chromatic tuner optimized for the Oud. It supports two modes of operation: manual and automatic. In manual mode, it operates as a general purpose tuner. In automatic mode, it cycles through all the strings of the Oud, instructing the user to tighten or loosen each string until tuning is achieved. Choose one of 10 common presets or define your own custom tuning. Automatic mode is also a quick way to make sure your Oud remains tuned. Supports Solfege and letter notes. Plays reference tones for tuning by ear.
