"from Scratch" Dsp Chains

Post your ‘From Scratch’ device chains here!
what i mean: i’ll start with a simple example called the perfectkick (haha)
how to use: start a renoise song, F5 to sample editor, F11 to create, create sample of length: 1
now load the .xrnt on a track, and even though there’s no starting sample/sound you can create a kick drum with keys from C-4 through about C-5 (use own judgement).
I’ve got some more of these but want to see what y’all people have. :D
