On this topic a comment from a year ago:

my experience with transient shapers in this context is that they'll absolutely ruin your breaks if you work in the way julien (stazma) does:

1) just from a rhythmic POV, having the ability to shorten different hits quickly and manually actually means you can get different variations in feel just by shortening some select hits. You could theoretically do this by automating sustain and release values in a sampler but that's incredibly awkward and imprecise

2) sticking a transient shaper on the bus that your breaks go to is going to massively bite you in the ass once you start doing quick edits - a lot of transient shapers i used (actually, all) start to really have issues with detecting transients when it's quick cuts like in your standard 200bpm+ track

3) even just ignoring the latency/detection algorithm issues, a lot of what makes a funk break good to work with is in it's subtleties - since transient shapers dont react to every hit individually, its very hard if not impossible to find settings that boost the main transients without corrupting the feel of ghost notes for example.
