The logic I need is pretty straight forward, but I am having a hard
time replicating it using PHP functions. I will try to break it down
to it's simplest form:
I have a field that has several lines of text. Chords and Song Lyrics.
The "Chord" lines begin with an asterisk "*" and end with the line
break. This is the string I want to parse. Lines with no asterisk at
the beginning are ignored.
Based on 3 arrays of NOTES, I want SUBSTITUTE the text (based on exact
text character patterns - just NOTES not the chord type) of the lines
in my field that start with an asterisk "*".
original_chord_array = A, A#, B, C, C#, D, D#, E, F, F#, G, G#
transpose_up_array = A#, B, C, C#, D, D#, E, F, F#, G, G#, A
transpose_down_array = G#, A, A#, B, C, C#, D, D#, E, F, F#, G
It is important that it only effects EXACT strings. Notes will always
be capitalized and chord types will be lower case. Maybe we can use
that characteristic to better identify what to change. Here are some
examples of chords:
A
Asus7
Csus add9
Dmaj7
F#m7
G#
C#dim no3
When I transpose UP these chords, just the NOTE should change:
A#
A#sus7
C#sus add9
D#maj7
Gm7
A
Ddim no3
When I transpose DOWN these chords, just the NOTE should change:
G#
G#sus7
Bsus add9
C#maj7
Fm7
G
Cdim no3
I am working on a function, but still not producing the proper
results. Hopefully this break down is more clear and someone will bail
me out ;-)
Thanks again for the feedback.

Changing the NormalKeyID and using that ID with NoteSequenceNumber
should give you the new note to play.
I think.
