Were my ear better I wouldn't need to bother you folks with this, but alas . . .

I need to enter both major 7 and dom 7 augmented chords -- i.e., 1 3 #5 7 and 1 3 #5 b7, but I'm not sure I'm doing it right.

The editor seems to accept: C+, C7+ and C+7. But it will not accept the triangle for major AND the + for augmented both, in either order. When I try to enter the triangle, it enters ^ instead, and will not play that chord back.

Does C+7 play back as C major 7 augmented or C dom 7 augmented?
What does C7+ play as?
What does C+ play as?

Thanks very much.
