A randomized drum machine.

Play non-repeating drum beats.

This can be used for:

• Creating a drum track for twelve tone music intended to be used for modern dance.
• Generating audio that can be sampled and sliced.
• Listening to experimental jazz drums for hours and hours on end.

Requirements

• SDL2 (including sdl2_image and sdl2_mixer)
• Download and extract the drum samples, either manually or by using make run.
• g++ that supports C++20.
• pkg-config
• make

Build

Tested on Arch Linux and macOS.

• Build with make.
