Aimed at the dance scene, HammerHead is a simple software drum machine similar to the Roland TR-909. You can use it to create techno loops and jungle patterns, and record your actions to a high-quality, noise-free WAV or RAW file for use with your sampler or sequencer. HammerHead also features adjustments for tempo, shuffle, feedback, and distortion, as well as the ability to export drum loops by measure or by entire session. It includes 23 separate drum patches and six complete loops, plus a feature to implement banks with six samples of your own, making a total of 35 samples that can be used at one time.

Best of all, it's 100 percent freeware. Most music-creation software is mired in overly complex interfaces and indecipherable jargon. HammerHead Rhythm Station 1.0 couldn't be more different. Although the software doesn't have much in the way of features, it doesn't need to. Six channels, 16 beat tracks, and basic tempo control provide a straightforward way to make unique beats. Any track worth saving can be exported as a CD-quality WAV file. Experienced beat aficionados may tire quickly of the minuscule sample library and effects tools, as well as the complete lack of integration with other music software titles. The percussion tool makes beat composition an effortless endeavor, even for those who have never used a drum machine. However, the software couldn't be more perfect for beginners who want to learn the drum-machine basics.
