I think I remember reading somewhere that you can change the colour (color for all the US folk :-) of this dot.

I tried the help option in serato and the manual but couldn't see anything about it.

Can you do this?

Yeah, but not in bulk. Choose the grey dot when you map the song, and click on it, a color pallete (?) will appear.

cheers nik...

when u say 'map the song' are u meaning load it onto one of the virtual decks ?

Yes, then you will see a bigger grey dot (I think on the left bottom side of each virtual deck).

aaaaah cool .... got u now...

thanks...

oh thats cool i should do that
