seriously just change this to HD, then change HD to MX, and then create the new NM. the '++' sign doesn't help it anymore
00:01:479 (1479|0,1923|3) - make them normal notes
00:09:923 - add note
00:10:812 (10812|1) - move to 1 for balance
00:11:257 (11257|1) - move to 3^
00:12:812 - add note, you mapped to the piano
00:13:034 - ^
00:13:257 - ^
00:13:479 - ^
etc. you can actually do a stream on the piano sound
00:26:812 - pattern like this fits better i think v
00:28:368 (28368|2,28479|2,28590|2) - do something about this unnecessary jack
00:44:590 (44590|2,44812|2) - what is this? I really don't recommend you to do this. It only gets more unreasonable
00:45:479 (45479|0,45923|0,46368|0) - ^
00:47:257 (47257|0,47368|0,47701|0) - ^, etc.
I stopped modding halfway and skim the rest part. They basically had the same error e.g. misplaced notes, missing notes, ghost notes, unnecessary jacks (only use jack on notes with the same pitch/sound, pattern consistency and balance issues. you can still improve a lot on this diff, i hope ou can find more mod, and sorry if my mod is a little bit harsh
