Before I make a Wishlist post, I want to see if someone can give me a solution for a chord spelling that would work in BIAB.

These two chords are in sequence in Lembra de Mim, a beautiful ballad by the incredible Brazilian composer Ivan Lins. This is from a chord/lyric sheet intended for guitarists to play and sing, and I do not spell some chords the way they do. For simplification I've transposed it from C# to the key of C.

C4(7M/9) resolving to C4(7/9)

I think that first chord means, C root with a 4, major 7, and natural 9. Spelled up from the C root, it would be C - F - G - Bnatural - D.

I don't think BIAB has any way to do that. When I try chord spellings like C9sus+7, or CMaj9sus, then BIAB doesn't accept the entry. I can't think of a way to do it with a slash root, either, because I need the C in the bass. The closest sound I can get is Cmaj9 but I lose the F that carries over.

[The second chord is C9sus. The 7 would be a minor or dominant seventh. This, BIAB can do: C - F - G - Bflat - D.]

So, how do you do a major 9 sus? Suggestions?
