This tutorial was done using Live 8. You can still find the Live 8 Compressor & other Live 8 resources in the Live 8 Legacy Pack from Ableton using this link https://help.ableton.com/hc/en-us/articles/209773685-Live-8-Legacy-Pack
Just open the Live8LegacyLibrary_r30431_v9.0.alp with Live 9 after download & it will install in your Ableton Packs.
FL is my DAW of choice, but I see how I can incorporate elements taught in this course into my FL work.
Thanks. I signed here to watch your video
