Accompaniment Machine 3.0
The Accompaniment Machine (AMac) is an easy-to-use program that lets you create professional-sounding custom accompaniments to any song, even if you have no experience in composing and arranging. 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. The package includes a library of over 7000 tested styles and hundreds of ready-to-use accompaniments. The programs Style Customizer and MIDI Doctor are included free.
