BEATS Drum Machine

BEATS is a command-line drum machine written in pure Ruby. Feed it a song notated in YAML, and it will produce a precision-milled *.wav file of impeccable timing and feel. Here's an example song:

Song:
  Tempo: 120
  Flow:
    - Verse:   x2
    - Chorus:  x4
    - Verse:   x2
    - Chorus:  x4
  Kit:
    - bass:       sounds/bass.wav
    - snare:      sounds/snare.wav
    - hh_closed:  sounds/hh_closed.wav
    - agogo:      sounds/agogo_high.wav

Verse:
  - bass:             X...X...X...X...
  - snare:            ..............X.
  - hh_closed:        X.XXX.XXX.X.X.X.
  - agogo:            ..............XX

Chorus:
  - bass:             X...X...X...X...
  - snare:            ....X.......X...
  - hh_closed:        X.XXX.XXX.XX..X.
  - sounds/tom4.wav:  ...........X....
  - sounds/tom2.wav:  ..............X.

And here's what it sounds like after getting the BEATS treatment. What a glorious groove!

Current Status

The latest stable version of BEATS is 1.2.2, released on June 12, 2011. This is a minor release which includes two bug fixes:

• Bug fix: Compatibility issues with Windows
• Bug fix: Return the correct status code when BEATS terminates, to improve scriptability.

Installation

To install the latest stable version (1.2.2) from rubygems.org, run the following from the command line:

gem install beats

Note that if you are installing using the default version of Ruby that comes with MacOS X, you might get a file permission error. If that happens, use sudo gem install beats instead. If you are using RVM, plain gem install beats should work fine.

Once installed, you can then run BEATS from the command-line using the beats command.

BEATS is not very useful unless you have some sounds to use with it. You can download some example sounds from http://beatsdrummachine.com.

Usage

BEATS runs from the command-line. Run beats -h to see the available options. For more detailed instructions, visit https://github.com/jstrait/beats/wiki/Usage on the BEATS Wiki.

The BEATS wiki also has a Getting Started tutorial which shows how to create an example beat from scratch.
