Gary Garritan: A Personal Orchestra for Everyone. The Garritan Personal Orchestra includes Garritan's award winning orchestra samples, music notation software (Overture SE-4), sequencing software (Cubase LE), and a sample player. It runs on relatively modest personal computer hardware (PC or Mac). It costs $250.
