Countrypicker, that post didn't seem to register on the ol' radar. I was in your position a couple of years ago, and I understand your frustration. But the advice you got is all good. There is no substitute for poking around and thinking: "where else can I find the note I'm after?" That's how I discovered a nice way to find a major seventh chord. (Go up 2 frets, A&B pedals in, and play 9,7,6, and/or 5.) You have to think what the pedals and levers do, of course, when exploring.
That's all "getting to know your instrument". And you can always change your copedent if you want a particular effect. For example, I'm currently using "raise E's" and "lower E's" on different knees so that, with the "up 3 and use A&F" major chord I can seamlessly go from the second note of the scale to the third, without that annoying "dead zone" in between if they are on the same knee.
It's all part of that journey we all try to make towards mastery of this amazing instrument. Good luck!
