Very useful and educational addon indeed. Especially the pull down menu against each chord.



Future improvements could include:


Slash chords with chromatic bass notes

Including dimMaj7 as a chord option (needs adding anyway to the chord list )

b5th substitutions

Other parallel harmony options based on negative diatonic harmony with a shifted axis

A Modal version of the app with a full list of scales and possible chords.

Progression builder try outs based on the number of common tones between chords




* There should also be the ability to double the slash chord bass tone in the upper register instrument
