Hello, i’m building a Sampler / Sequencer using the minim library.  
I’d like to add the option to add reverb to the tracks, seeing that the “Sound” library had one i tried to use it but sadly they seem not to work well together (AudioSample being a variable that i think exist in both). Any help ?

I’m not sure – although there are passing mentions of reverb here:

- [Repository search results · GitHub](https://github.com/ddf/Minim/search?q=reverb)
- [Wiki search results · GitHub](https://github.com/ddf/Minim/search?q=reverb&type=Wikis)

…and here is the JSyn implementation in Processing Sound:

A while ago I extracted and adapted the Freeverb implementation from RasmusDSP (the precursor to Gervill from the JDK) as a JAudioLibs AudioOp. You should be able to plug it in to any audio library that uses Java float[]
