Sound clips have been trimmed and edited from the following free audio files:

If you'd like to add or update the sounds on your soundboard, more audio clips can be downloaded from sites like http://soundbible.com/ or https://freesound.org/

You will need to convert the files to the appropriate format for microcontroller use. See this guide on how to do that.

When you have a file converted, you can name it like the files in the xmas directory. For example, say you downloaded a clip and you wanted it to be activated on the second row, end key. That is the 16th key counting from upper left. Rename 16.wav to 16-old.wav and name your clip 16.wav and copy it into the xmas folder on the CIRCUITPY drive. Now your sound will play when that button is pressed. Note for keys 1 to 9, add a leading zero, like 01.wav02.wav, etc. so all filenames are two digits.

No Mix & Match on mono and stereo files, please.

Make sure your audio files are exported as 16-bit PCM WAV at 22,050 Hz and they are all Stereo or all Mono -no mix and match!
