Two interesting video tutorials today. The first one is about Ableton Sidechain Compression and the second is about Ableton Sidechain Autofilter. I like that these videos don't focus on the basics (such as describing threshold, ratio), but on some small details ignored often. For example first video nicely describes the difference between Post FX, Post Mixer setting, the second video very nicely describes Auto Filter's knob called: envelope.
Overall, professional videos by Loudon Stearns from Berkleemusic.com, where "everything" is crystal clear :)
