Okay, I think I found it -- and not a moment too soon, b/c it's after 1:15 am, and my damn alarm is set for 5:30. Guh!

It is a soloist setting, not a chord-sub thing (unless it's also somewhere else). Sorry for mentioning this whole thing in the context of Jazz-up/down of chords and chord subs. My bad.

If you press the Soloist button, the Select Soloist panel opens up. Pretty complex thing, that. But -- Lo!! -- there's more. Press the Edit... button on the right to open the Soloist Editor window. On the bottom right are all sorts of boxes to check regarding the treatment of major chords, dominant chords, and the V chord in particular.

I'm not sure I understand the bottom one: "Treat all 7th chords like Major." Does that mean Maj7 or Dom7? I don't see how treating Dom7 chords like simple major triads can make a solo sound more bluesy. On the other hand, I can see how treating Maj7 and Maj9 chords as simple major triads would make a solo sound more "bluesy." And since the word "dominant" was used for the other check boxes, I'm assuming that "7th" means Maj7.

But I suppose that's something ELSE to try out! TOMORROW!

Uh, I mean later today!
