AMac 3.0, a quantum leap

I started working on the Accompaniment Machine about two and half years ago. At that time, I had relatively narrow goals. I had purchased a Yamaha keyboard that I really enjoyed except for some limitations:

  • It had only 170 built-in styles, and it was difficult to load additional ones.
  • It could play only a limited subset of style sections (MainA, MainB,…).
  • I couldn’t figure any way to do fades besides turning the volume wheel with my nose.

I purchased a program that claimed to solve the problems. It proved to be unreliable and unwieldy, so I set out to write my own. The Accompaniment Machine (1.0-2.0) was the result. Effectively, the program replicated the auto-accompaniment function of keyboards, but on steroids.

In the AMac development process, I created a reliable engine for style performance. I realized that the program would have a much broader audience if I introduced a function to advance chord sequences and style-section changes automatically. Hence, AMac 3.0. Given a guitar chord sequence or fakebook, users can easily create and arrange custom accompaniments for any song in the universe. AMac could be a valuable resource for vocalists, instrumental soloists, choirs, singing groups and keyboardists.

I decided a demo would be much more effective than a list of program virtues. This video introduces many of the program features with lots of musical examples.
