We agree, the bass note (or chord inversion as it is also sometimes called) is very useful information. After some investigation, it appears this would be a very large undertaking. We have however been working on this and we hope to implement this soon. Stay tuned!James Clarke supported this idea ·James Clarke commented
I think that it would be really helpful to bassists who want to create chord-based grooves if Chordify would provide additional chord-diagram options for them. Plus, I have a tenor guitar that I tune to Perfect 4ths, and so this would help me and other, similarly-inclined tenor guitarists.
