A - C# - E - G - F
A7b13
This happens all the time in Scaler.
Actually, A7b13 is very easy to understand. The notes are A - C# - E - G - F
At that time, I entered A - C# - E - G - F in Scaler
This is it Fmaj9(#5)/A
I wonder if this will be better in Scaler 3.0?
you do need an extra long finger to reach the high F though 
Same thing for C E G A which is C6 or Cadd6
Scaler 2 show the chord as a Cmaj add13.
Good question! Scaler 3.0 might improve chord recognition, but it depends on how it handles extended and altered chords. Have the developers mentioned any updates on this?
