I was searching around and couldn’t find them. Kinda disappointed ;/
Chords I’m trying to make would be for example Cm7(#11) using the notes C, G, F#, B, E, or maybe an AbM7(add13) like Ab, Eb, G, C, E(natural), etc.
Are they possible here on hookpad?
Nope, they aren’t. You can use a 7th chord and put #11 or 13 notes in the melody, but you can’t add them to the chord itself. There are lots of posts on the forum about what is and isn’t possible (e.g., here and here)
That sucks. It’s so inconvenient, but thank you!
