A drum pattern composition tool, named Auto Drummer, created using answer set programming. Auto Drummer was ideally built to aid drum pattern programming in electronic music production. The style of drumming outputted is focused around traditional Drum & Bass 'breakbeats' however, the pattern generated can be used in any genre of music, particularly less constrained outputs.

The patterns themselves are primarily modeled using answer set programming in AnsProlog. Data handling and the GUI are handled in Python. The patterns are outputted in MIDI format for easy implementation in any DAW.

To start generating drum patterns, open the executable file. Click 'generate' to create your first one bar pattern. The GUI makes it clear what parameters can be controlled.

To use the single file distribution, it must be installed on Windows OS. The distribution may run on Linux OS and Mac OS through Wine, although this is untested. Download Wine from https://www.winehq.org/. To run Auto Drummer enter

wine Auto Drummer.exe

Everything necessary to generate the patterns themselves is listed below or included in the installer for users with a Windows enviornment. However, to play preview audio of the patterns, FluidSynth must be installed. This can be done by consulting the FluidSynth website, http://www.fluidsynth.org.

If you are not using a Windows enviornment, to deploy from the command line, several packages are required as well as a Python 2.X or 3.X build. Download Python from https://www.python.org/downloads. All other necessary packages can all be installed via pip once Python is installed.

pip install pyqt4
pip install numpy
pip install matplotlib
pip install MIDIUtil

Depending on your version of Python, PyQt4 may have to be installed with a wheel. If a pip installation does not work, try downloading the relevant wheel from https://www.lfd.uci.edu/~gohlke/pythonlibs/#pyqt4. Then enter on the command line

C:\path\where\wheel\is\> pip install wheel_file.whl

Users not using a Windows enviornment will need to also install the Clingo package. Please consult https://github.com/potassco/clingo/releases for more information. The most simple method for installation is with conda. i.e.

conda install -c potassco clingo

Once everything is installed correctly, the program can be run with

python auto_drummer.py
