First,You should make a double note to all time that have a cymbals. (except 1/4 beat)
Next,arrange your note for hand balance (if possible) because many novice players sometimes confuse with 2 note in one column of 1/4or1/2 beat.But anyway,I don't want to break your own pattern so I'll only write it
Oh,it's Drum and Bass with long lead melody,so it's your choice to make a this diff to LN map or make it a 1/2 double&single note with rarely LN.
Also,don't forget to add Kiai Mode
Column : 1|2|3|4Offset : I think it's too fast (290 it's my suggestion)
00:17:088 (17088|0,17088|1) - delete one note
00:17:345 (17345|3) - arrange a note to 1/2 beat
i still confuse :/00:17:688 (17688|1,17688|0) - ^ and delete one note
00:18:459 (18459|3,18459|2,19145|2,19145|3) - make it single note per 1/2 beat
i will take this , and re arrange all DnB make it consistant00:19:488 to 00:20:688 - Pattern Suggest :
https://osu.ppy.sh/ss/5425773 rejected00:31:573 (31573|1,31745|2) - Ghost note,delete it
done00:39:030 (39030|2,39030|3) - delete one note

00:52:745 (52745|1,52745|3,52745|0) - I recommended don't use triple note on NM Diff,so delete one of it
00:53:430 (53430|2,53430|0) - Overmapped,it just a snare,so delete one of it
01:00:116 to 01:03:373 - Pattern Suggest :

https://osu.ppy.sh/ss/542591101:06:630 (66630|0,66630|1,66802|3,66802|2) - Make them single note

https://osu.ppy.sh/ss/5426887 or like this
https://osu.ppy.sh/ss/542690001:31:659 (91659|2,91830|3,92002|2,92173|0,92516|0,92688|1,92859|3) - Don't put notes for follow melody of vocal or another that is not a drum (because your pattern is follow the drum sound in all section) so think and make it a new one
01:38:773 (98773|1,98945|2) - Ghost note like the first one (same pattern),and it's hard for novice player because it's quick 1/4 that's not continue the stair (jump note)
01:42:630 (102630|2,102802|3,102973|2,103145|1,103488|0,103659|1,103830|2) - Don't put notes for follow melody of vocal or another that is not a drum (because your pattern is follow the drum sound in all section) so think and make it a new one
01:46:488 (106488|3,106830|1,106830|0) - arrange it to 1/2 beat
01:51:373 (111373|0) - should end at 01:52:059
01:51:888 (111888|1,112402|2) - it's same key sound so delete 01:52:402 (112402|2) and make 01:51:888 (111888|1) longer from 01:52:059 (from previous LN suggest) to 01:53:430
01:55:488 (115488|3) - move to column 2 for key pitch
01:56:088 (116088|1) - move to column 4 ^
01:59:259 (119259|1) - this should end at 02:00:802
02:00:973 (120973|3) - this should start at 02:00:802 (from previous LN suggest)
02:02:345 (122345|0,122859|1,123288|2) - same as previous LN suggest
02:04:402 (124402|0,124402|1) - Overmapped,delete it one
02:05:945 (125945|2,125945|1) - ^
02:06:288 (126288|0) - this should end at 02:07:145
02:07:830 (127830|2) - arrange it to 1/1 beat
02:21:888 (141888|0,141888|3,141888|1) - don't use triple notes like last recommended
02:22:573 (142573|0,142573|2) - delete one note
I choose to skip to 03:23:259 because it's same pattern as i mod
03:23:259 (203259|3) - move to column 1 for pitch key
03:26:002 (206002|0,206002|1) - Overmapped,delete one note
03:28:745 (208745|2,208745|3) - ^
03:30:116 (210116|1) - same pitch key delete it,and make a previous LN more longer to 03:31:488
03:32:859 to 03:42:288 - OMG,it's so overmapped.Delete it all and make a LN (I think a long trill it's hard for novice player also)
03:43:488 (223488|3,223488|0,223488|2) - It's clap sound,so delete one or two note(s)
04:27:716 to 04:49:488 - It's end and last part of song (and also low sound) I think it should be a LN with 1/1 beat note.
i will re arange pattern later , but almost all of mod applied , your suggestion is.. i will consider it too
