Thanks @Ryan and @Segon! I usually use a lot of 2:2 trig conditions to make patterns sound longer than 64 steps, but in this case I made six fairly straight forward patterns without trig conditions and chained them together (I do it in the beginning of the video). The reason I did it is because I wrote the track to have a 3/4 time signature, so I set the patterns to 24 steps.
rant warning: When I work on 64 step patterns and I want to make changes near the end, I can usually just copy that page to another pattern, make changes, then paste it back. But with 3/4 time sig it gets weird, because the first downbeat per bar would be on steps 1, 13, 25 and 37 instead of the usual 1, 17, 33 and 49. This makes it so that when I copy a page, I’ll be copying the last part of one bar, and the first part of the next bar. To get around this I just use more patterns and chain them.
