In this tutorial i will be showing the settings that i use. it's very simple to follow and you can always change them depending on the song you use.
1. ExpressFX Reverb
2. ExpressFX Delay
3. ExpressFX Equalization
4. Pitch Shift
5. ExpressFX Chorus
These settings have helped me to not get copyright strikes on youtube. Sometimes even they don't work so i advice you to include more song mashups in your videos which will help too.
