Reader Gibran Curtiss Salomao shared this video demo of the Tambores, an open source DIY Eurorack drum machine.

The Tambores offers 3 channels to play any uploaded instrument, plus a tone control for the 2 first channels. There is a gain/distortion available too.

Details about Tambores are available on GitHub. The project is based upon Bret Truchan’s project, called Equation Composer.
