Missing accidentals for doubly altered chord extensions

When manually altering a chord extension that is already altered by default, Hookpad doesn’t reflect these alterations in the chord name. For example if we’re in the key of C major, the 9th and 13th of Emin are already flat by default, so if you flatten them again the chord name would have to be em7(♭♭9♭♭13), but Hookpad displays it with single flats.

Also if you sharpen the 9th of a chord that would otherwise have a flat 9th, it is displayed as ♯9, when it should just be displayed as 9. The same thing applies to chords that have flat 11ths by default (iiio in Phrygian Dominant and viio in Harmonic Minor).

I’m only talking about the absolute chord names by the way - the roman numerals are totally fine.

Hi, I’m not exactly sure about this. Something is definitely wrong. I’ll discuss with the team, thanks for bringing this up!
