I came up with a pattern I liked using tap to find, but didn’t find a close match ( a problem for another time). But in dragging my pattern to the timeline the pattern changed. It was a straightforward bass, snare and closed hi-hats, with two on-beat open hh in the first bar and two off-beat hh in the second bar. This became no open hh in the first bar and four open hh in the second bar. I tried this a few times but with the same result. Why am I losing my pattern? Quantising? Ideas appreciated. Thanks.
