+Now we can press the second to last button on the kit and send a **bang** to our new **pd boop**. We won't hear anything yet because we haven't connected it to **pd speaker**. Do that now.

+Now see if you can make the two buttons play two different notes.

+But why stop at two buttons?

+Try to connect the other four buttons on your kit to your patch in the same way that we connected the first two:
+* first **copy** and **paste** the **bang**, **message**, and **pd boop** objects
+* rearrange them as necessary
+* connect them to the four outlets on the object with the long name that are next to the two we already have connected. 
+* finally connect the new **pd boops** to the **pd speaker**

+Let's try to play a song

+You should now have 6 **pd boops** that you can control with the 6 buttons on your kit. 
+You should also have 6 **messages** that you can use to tell your **pd boop**s which notes to play.
