Remix breakbeats or other sample loops on the fly with the Breakbeat Breadboard! Thanks to the CircuitPython audio library mixer, it's easy to do!

This project is easy to build, and the colorful tactile buttons are irresistible to push. Hold any button or combination of buttons to un-mute the synced loops like a DJ killswitch -- the music loops play constantly in the background, the audio mixer takes care of the rest. No tricky sync code to worry about.

While this project uses eight buttons, the KB2040 has enough GPIO pins to comfortably increase this to sixteen buttons before requiring a diode matrix.

You'll also need a electrolytic through-hole capacitor for audio filtering, a 1µF or 2.2µF cap works well. This is just used to filter some of the high-end noise.
