00:40:815 - I think can reverse the stream direction into the left to represent the pitch change, also to make some symetrical pattern like this -> https://osu.ppy.sh/ss/18432996/8881
00:41:315 - tbh I kinda confused about the chord usage at this part, why is prominent kick here was represented with single? I guess it should be double? by percussion based, it should be:
00:41:315 - add a note
00:41:481 - remove a note
00:42:315 - add a note
00:42:481 - remove a note
00:43:981 - add a note
00:44:148 - remove a note
00:44:898 (44898|0) - remove, haven't on 1/4 stream section yet
00:44:981 - add a note
00:45:148 - remove a note
also need to rearrange if the pattern looks broked by the adjustment, or you have any intention on current pattern?
00:46:364 - Any particular reason why you stop doubling these from this point onwards? (see 00:45:197 (45197|2,45197|0), 00:44:697 (44697|2,44697|0), etc, all doubled regardless of having kick or not)
00:49:481 (49481|2,49648|2,49815|2,49981|2,50148|2,50315|2) - should avoid this long anchor, maybe 00:49:828 - https://osu.ppy.sh/ss/18433057/3f44
02:19:363 (139363|3,139863|2) - I'm assuming these two notes are here just to keep the flow? (that'd be perfectly fine, but wanna make sure). Just pointing out bcs they do not have any percussion onto them
02:53:647 - to make similar motion as 02:48:314 (168314|0,168481|0,168647|1,168647|0,168814|1,168981|1)
might do somthing like -> 02:53:397 - https://osu.ppy.sh/ss/18433091/3755
02:54:030 (174030|1,174030|0,174113|2,174196|3,174196|0,174280|1,174280|2,174363|3,174363|0) - This pattern should maybe be layered the same way as this: 02:48:696 (168696|1,168696|0,168780|2,168863|3,168863|1,168946|2,169030|3,169030|0,169030|1) - As they sound identical
02:56:530 (176530|0,176696|0,176863|0,177030|0,177196|0,177363|0,177530|0,177696|0) - Unusually long anchor in this part, moving 02:56:863 (176863|0) - to the second column would fix the problem.
04:02:647 (242647|1,242647|2) - here and here 04:02:980 (242980|2,242980|0) can be expressed as single coz the sound seems still fading in
idk the timestamp seems on older mp3 but I think one of them 04:05:063 (245063|1) (tom sound) is still on 1/6 snap for me, please recheck, as for me should be like this => https://osu.ppy.sh/ss/18433123/d0a2 (also arranged for playability
04:07:313 (247313|1) - I think based on later pattern, it worth double? see 04:08:647 (248647|3,248647|0)
and maybe can split this jack 04:11:147 (251147|1,251147|2,251313|1,251313|2) as it appears to be the only jack on triplets-doublets pattern at this section
05:14:147 (314147|2) - minor thing to move this on col 4 maybe? to avoid anchor if it's not intended
06:46:813 (406813|0) - may do something with this long anchor on col 1 since the sound does not support this. imo
07:36:612 (456612|2,456737|2) - May be unexpectedly tricky to play, probably worth moving first note to col.4
