Ok I need to learn how to sidechain guys? What is the best plug in for it ?
Not sure what DAW you use, but I find that the bundled compressor in Ableton Live 10 is a great place to start. Any theory and techniques you pick up here will translate to other 3rd party plugins. Great place to start: https://www.ableton.com/en/blog/sidechain-compression-part-1/
