9. How to import a song into ProChords
Let’s say you have a chord progression you would like to import into ProChords.
At the moment ProChords doesn’t support import from other sources, so you will have to type them in manually.
In most songs you will find the vast majority of chords among the find match suggestions – and often among the first 5.

If You don’t find exactly the chord you where looking for, pick another one closely related.
When you have entered them all, use the edit panel to fine tune them. I use to be the fastest method.
