Mando 1.7 provides chord lookup for Mandolin, Mandola, and Octave Mandolin in standard tuning, and additional chord processing for 4 non-standard mandolin tunings. In the standard tuning library, 17 chord types are supported with 3 or 4 different fingerings each, depending upon the chord. To plot a chord diagram, select the root of the chord from the Root menu, and the type of the chord from the Type menu. Then, diagram it with the Form 0,1,2,3 buttons from the tool bar. Non-standard tunings do not contain these built-in chords, but full use of the Neck Window functions are supported.
