Hi,
First, thanks for the great app !!
I wanted to practice my phrygian scale and when trying to make a playback I didn't find the m7b9 chord in the pop up list (when I type it, it is not recognized)
I guess I missed something because its a usual chord, but I dont see an other way to write it and as the 7b9 chord is there, I don't see why the m7b9 is not
any clue ?
