Thanks Scott!!…All I had to do was look in “GROOVES” area of EZ Drummer GUI and there is “Cocktail”!!…I Was making things real complicated for myself….As soon as I saw your reply about Expansion Pack, I realized That I had to open EZ Drummer First..Not too sure if Cocktail Install Instructions clearly point out how/where to find/operate Expansions once they are installed?..But Thanks,All is well now here!
