PercussionStudio

From Henry Kellner:

Rhythm patterns are often difficult to remember, and even more difficult to read. Percussion Studio solves these problems with its simple rhythm notation system that lets you easily transcribe rhythms. It can play multiple instrument voices simultaneously, and each track is mutable so you can play along and learn individual parts. The program comes with a set of standard rhythms, and you can add your own instruments. It provides functions for automatic handset notation. You can also use Percussion Studio as a rhythm sampler with WAV files. The program allows simultaneous playing and editing, and plays note changes immediately. About 150 percussion instruments for download available.
