i don't think there's a gap. You are using enough basic - novice expressions with each other.
00:39:464 - 00:39:593 - If use a melody for correction, the expression will overlap, and it will not be consistent because it is different from my intentions. 00:40:234 - If expressing the melody, it should be the same here, so I'll keep it for consistency.
I don't use all LNs as melodic expressions in this part.
00:39:208 - 00:39:977 - My intended sound highlights the background synth sound, not the melody. This is to reprocess simple and easy LN patterns at high bpm.
And as you have figured out, 00:40:362 (40362|2) - because there is an intermediate drum burst, we add a strain representation to mitigate the repeatability of the pattern.
In this section you already mapped for piano except huge kicks so 00:47:798 (47798|3) unnecessary note that u mapped for drum, i'd like to say move this into 00:48:054 for piano instead
02:12:597 (132597|2,132854|1) - This section can be a little more complex, how about place them at 2-3? mapped 1/1 LN stairs from 4 to 1 and ends at 4 again is pretty awkward like last LN is having special than other LNs or something but its actually has same sound
