Hello!
Im trying to make a drum kit using arduino, I've got most of it sorted but I'm struggling to find a way to play one sound over another, say for instance hitting one pad directly after another should end the first sound whilst the second one is starting. If anyone knows if there's a way of doing this I could really use some help please.
Thanks!
just add the 2 signals ...
Hi,
Welcome to the forum.
Please read the first post in any forum entitled how to use this forum.

Do you have any code to show how you are getting the drum kit to play at the moment?
Can you please post a copy of your circuit, in CAD or a picture of a hand drawn circuit in jpg, png?
Have you googled
arduino drum machine
Thanks.. Tom.... 
Since you've given us no idea of what exactly you're doing now or how you're doing it's really difficult to advise you on what you might want to change.
If you really want one sound to stop instantly because you've hit another pad that's known as choking and it's a standard technique. It's normally used only for hi-hats because it sounds really odd if e.g. a cymbal sound stops dead when you hit the snare.

How are you playing that first sound?
