Other than that, I've been testing Half of Reatrack midi actions and so far so good ! It's not to be confused with the "so what" chord which is just an inversion of a min11 chord, which means it's already there in reatrack !Ī sibling chord would be the Q5, which is, you've already guessed, a stack of 3 fifhts. It's sometimes notated as Q4 or simply 4 (a quartal F# would be F#Q4 or F#4). Well, at least in Jazz and probably contemporary music. I feel its inherent simplicity makes it a more often used chord than ultra-complex structures. This one as you may know is simply 3 stacked fourths (a quartal C would be c-f-Bb). The only addition I can think of would be the quartal chord. While I'm at it, you've been pretty extensive in your chord database, going as far as referencing ultra exotic chords, C13susb9#11 or the like !
