Robby Greengold is a music arranger, music engraver, and composer at IndigoMusicBox.com. He developed the MIDI orchestration service there, providing composers an affordable way to hear their music performed with expressive techniques, vibrato, and dynamics that were originally intended. Composers and other music professionals finally have nuanced control over the sound of their music, and can use the mockups as part of a film score or part of their demo reel.
