«Rate Player» by joehigham

This is a player that I use for live work. It takes piano samples (or anything else I guess) and plays them in a rhythmic way that is also based on chord pitches. You'll see the GUI has (for me) chord names to remind me of what harmonic area this plays in. I'm using small sample of Morton Feldman's "Triadic Memories", if that's of any interest.
