Tried to blend both high scream and clean vocals, think it sounds pretty good. At least a lot better than with just the clean vocals. What do u think? Would also need opinions on the vocal processing in whole, I'm having trouble to make the harmonizing vocals blend with the standard vocals. Vocal post-processing seems to be my Achilles heel when it comes to mixing
