======Chords======

When you initialize a track as a CHORD track type, the first parameter layer is a special "chord" layer.  Data on this layer is represented as upper or lower case letters with an octave offset.  The letters on CHORD layers are not related to note names - For example, a "C" is not necessarily a C chord.

When not transposed, the chords in a chord layer are all C chord variants.  You can play other chords by transposing the chord track.  If you're not up on your music theory, you might want to use [[forceScale|Force-To-Scale]] when transposing chords to ensure that your results are always in key.

When not transposed, the letters correspond to the following chords: 


  * **A-C:** Major I, Major II, Major III (transposed variants)
    * **A:** C Major (Root position) (notes: C E G)
    * **B:** C Major (1st inversion) (notes: E G C)
    * **C:** C Major (2nd inversion) (notes: G C E)

  * **D-F:** Root note, 3rd note, 5th note (single notes)
    * **D:** note: C
    * **E:** note: E
    * **F:** note: G

  * **G,H:** Root+3rd, Root+5th
    * **G:** notes: C E
    * **H:** notes: C G

  * **I-N:** Maj6, Maj7, Maj8, Maj9, Maj10, Maj12 (4-note chords)
    * **I:** C Maj6 (notes: C E G A)
    * **J:** C Maj7 (notes: C E G B)
    * **K:** C Maj8 (notes: C E G C)
    * **L:** C Maj9 (notes: C E G D)
    * **M:** C Maj10 (notes: C G C E)
    * **N:** C Maj12 (notes: C G C G)

  * **O-P:** Sus4 and Maj+
    * **O:** C Sus4 (notes: C F G)
