Since your files are missing i will provide steps to edit ByteController to work with Cog!
1. In Cog preferences edit Hot Keys.
2. Open ByteController in finder (right click - show package contents)
3. find next files: next.scpt, playpause.scpt and previous.scpt
4. edit files like this :
tell application "System Events"
keystroke "f" using {control down, shift down}
end tell
That code is for Ctrl+Shift+f ...
happy tweaking
