Is there a way to tell BIAB not to try to "blues up" my chords? For example, if I enter a simple C, Am, F and G progression for a poignant ballad, BIAB will occasionally slip in an Eb note while on the F chord, which turns it into an F7 which (in the key of C) ruins the whole mood by suggesting it's now become a sassy blues thing. Or, equally as jarring, if you've got a C and then a G (in the key of C) and BIAB slips in a Bb note while on the C chord, it suggests the next chord will be F, so when it goes instead to your G, it sounds ridiculous.

I seem to recall that there's a way to have BIAB "jazz up" your chords (and maybe "un-jazz" too?). Well, is there any kind of "un-BLUES" option, to keep those dominant 7th notes away (unless I ask for them, by, ya know, typing them in)?

Thanks.
