Create Chords takes single notes and adds 2 or 3 more notes to make a triad or seventh chord.
This version has an improved user window, minor keys and allows individual chords to be changed.
You first create an instrument/staff with measures containing single notes. Then run Create Chords on selected measures.
You can save the single notes from the selection before changing and then later reset some or all measures if you wish to start again.
They key can be changed and the also the relative positions of the notes in the resulting chords (root, third etc.).
Individual degrees can be modified.
Run Create Chords for the first time without selecting any measures and a help window will appear telling you how to use it.
Note. Only notes in the first voice are processed.
