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.

• 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

Tested on Arch Linux and macOS.

• Build with make.

• Press r to randomize the samples.

• Press p to pause toggle (try holding it down for an interesting effect).

• Press space to toggle pause, with a 200ms fade-out.

• Press esc to quit.

• Press a to play a kick drum sound.

• Press w or f to play a snare sound.

• Press d to play a crash sound.

• Press s to play a closed hi-hat sound.

• Press q to play a tom sound.

• Press e to play a ride sound.

• Press x to play an open hi-hat sound.

• Press return to play a snare sound with a tiny bit of delay added.

• Press m to increase the tempo.

• Press n to decrease the tempo.

• Press y to use the current settings, don't change the samples.

• Press i to toggle "random beat skip".

• Press j to toggle "use random beat silence".

Note that playing too many sounds at the same time does not always work.
