there's a bit of an explanation of each of the plugins below, but it's not a thorough documentation or a manual, it's just a bunch of notes i've written and a short description of the parameters

the peak detector is still a bit fiddly, so you'll have to tweak the params a bit until it works for the kind of sound you're giving it. the defaults have worked great for me, so i recommend you start from there and change as you see fit

### velociter
|
||||||
|
|
||||||
|
velociter sets random velocities to midi notes
|
||||||
|
|
||||||
|
params:
|
||||||
|
- `min_vel`: minimum velocity
|
||||||
|
- `max_vel`: maximum velocity
|
||||||
|
|
||||||
|
it'll set the velocity of every incoming midi note to be in the range `[min_vel, max_vel)`

issues and prs are welcome, but please open an issue before making any big pr, i don't wanna have to reject a pr where you have put a lot of effort on. if you are fine with that, ig go ahead i'm not your mum
