First of all, thanks for checking it out!
About peaking - went and checked levels of the resulting wav - just below zero, hence, I assume what you mean by "peaking" is just harsh drum sound itself, which i'm not gonna argue at all.
Instead, I'd like to share some insights:
TLDR: making it nasty allowed me to cheat and make reversed part sound kinda not-reversed)
Long story:
on a screenshot above :
Drums:
1, 2 - "normal" kick and snare envelopes, high peak then slope. (for reference)
But using "normal" kick and snare for such track would produce "swells" on reversed part of a track, which I wanted to avoid.
This why I went with some kinda symmetry:
3, 4 - waveforms I've generated and used instead of kick and snare - essentially, pulse waves with additional distortion, tuned somewhere in a ballpark of where snare/kick usually goes; attack and release are almost instantaneous. They sound harsh and nasty, but on a flip side - they sound identical when played forward and reversed.
Sidechain:
On top of "symmetrical" "drum" sounds, I've also went with really hard sidechain.
5 - average sidechain curve (for reference)
6 - mine - instantaneous and symmetrical too.
In normal situations. such hard curve is undesired and sounds bad, in my particular case it allowed sidechain to work the same on both normal and reversed parts of the track, while still giving illusion of "pump" effect.
On top of all that, there's some hard limiting on master bus producing -5 LUFS at loudest part.
All above allowed to masquerade the fact of drums not being exactly drums, achieve the same groove on a reversed part.
Harsh and unpleasant overall sound was a price to pay.
...and also SKILL ISSUES on my part!
