Merry Christmas mate.
You didn’t find the bits about chaining patterns of odd time signatures helpful? For instance, if you’re wanting to play in 7, Pattern A01 is two pages, a bar of four (16 steps) on page one, and a bar of three (12 steps) on page two? Then to get to the next bar of the pattern, put it on A02, then on to A03, etc. Enter song mode, or chain the patterns together.
This way you can visualize the 7 (or whatever it is) a lot better. Instead of having to think to yourself “okay my beat resets on the 13th step of the second page” which, for me, really fucks with my brain.
