From Sevilla Soft:
Alternative_Tuner is an accurate guitar tuner for high performance. It works automatically. Detects the string, the fret and the degree of deviation from the perfect pitch of the note.There is a list of alternatives tunings where some strings are lowered or tone up with respect to the standard tuning: EADGBE (MI LA RE SOL SI MI) giving the guitar different characters depending on the type of pitch.When selecting a type of pitch, 6 buttons representing the 6 strings are illuminated. Pressing one of these buttons hear the note corresponding to that string and having a reference sound of the note to reach.The indicators clearly show whether we raise or lower a string, or if the pitch is correct.Types of tuning:StandardDrop D tuningD for Flamenco RondeaOpen D tuningOpen G tuningLow C tuningOpen C tuning
