Mick Guzauski demonstrates how to use sidechain compression with the Avid BF-76 to make a hi-hat sit well in a busy mix.
By routing the bass drum sample into the sidechain input of the hi-hat's compressor, he creates more movement and ensures the hi-hat tucks in nicely with the rest of the elements.
This method also adds rhythmic interest without overpowering other instruments.
