The Accompaniment Machine (AMac)

The Accompaniment Machine (AMac) is an easy-to-use utility to create professional-sounding custom accompaniments to any song — even a beginning pianist can sound like a pro. AMac is an invaluable resource for vocalists, instrumental soloist, choirs, singing groups and keyboardists. The key is the program's ability to access the multitude of Yamaha-format accompaniment styles available on the Internet — virtual backup bands for your performances. Libraries of over 7000 tested styles and a songbook of over 300 ready-to-use accompaniments are available.
