No Programming Needed

You just need to change the Audio Files to add your own sound FX
Step 4: Load Sounds on the MicroSD Card.
The Touch Board comes pre-loaded with an Audio Guide to help you with all it’s features. One of the first things you may want to do is change the sounds that the Electrodes will trigger. Changing the sounds on your Micro SD by plugging in the micro SD card into your computer, it should show up on your desktop under the name “TB AUDIO”.
When you click on it, you should see a series of files that look like the image on the right. The document titled “README.txt” contains instructions on the Touch Board Audio, as well as the Audio Guide in written form. Don’t delete this document unless you remember everything and will never forget the instructions ever again.
Amie's in Game-Hint:
It's important that you keep all the files in the top level of the SD card, a lot of these files are related to the workings of the Touch Board, so deleting or moving them may affect your board’s functionality. You will see twelve tracks titled:
TRACK002.mp3 up to TRACK011.mp3
00 is for electrode 0, 01 is for electrode 1, 02 is for electrode 3, each TRACK name has to be named to match the electrode. Also make sure you do not have multiples on the SD Card (example TRACK000.mp3 TRACK000.mp3)
These are the files you need to replace to input your own audio. Bare Conductive recommended  mp3cut to clip your own mp3 sound files. It free, simple and easy to use. Make sure the files are named correctly on the sd card.
