00:52:757 (2,3) - Might want to move this away from each other for readability. It's not that hard, but i think the readability is quite poor in some stack slider like this.
00:54:844 (2,3) - 00:56:931 (2,3) - 01:42:844 (2,3) - 01:44:931 (2,3,4,5) - 01:47:018 (2,3) -
i'd not say that's really hard to read because all these pattern have same flow.
also if they'll be spaced enough much to not be overlapped, there will be no contrast with patterns like 00:51:714 (1,2) - which is emphasizing drum, when patterns you mentioned is emphasizing synth
id prolly just do this maybe cuz then u dont have to unstack and the spacing is a lot smaller https://imgur.com/D6J7Ygt
