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 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

### cronchy bits
bit crusher
params:
- `cronch`: the ammount of bitcrushing. 1 is extreme crushing, 500 is basically no crushing
- `kind`: type of rounding to use in the crushing
changing the kind will not affect the tone much, but it's still a nice option to have
there's 4 available kinds:
- `[0.0, 0.25)`: round
- `[0.25, 0.5)`: truncate
- `[0.5, 0.75)`: ceiling
- `[0.75, 1.0)`: floor

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 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
