Turbocharging Yamaha-format styles

Styles are great additions to Yamaha keyboards. They make it possible for players with moderate ability to create good sounding songs. On the other hand, standard style files have several limitations. Like MIDI files, they are constrained to support all hardware designed over a span of 40 years. The challenge for improving styles is […]

Tap-Tap-Tap

Most Yamaha-format accompaniment styles for keyboards include multiple introductory sections (IntroA, IntroB, IntroC). The loose convention is that IntroA is relatively simple and starts with a measure of downbeats. This presents a problem if you want to use the introduction in a performance. Furthermore, the downbeat is unnecessary in the Accompaniment Machine — the program […]

To minimize […]

Where to get keyboard style files

Style files in the format defined by Yamaha are central to the Accompaniment Machine (AMac).

The first stop (always at the top of the search page) is the official Yamaha store at http://www.yamahamusicsoft.com. I’ve passed by there […]

Standard keyboard accompaniment style libraries

The function of the program is to convert ordinary style files to the compact, universal PureStyle format. After some tune-up to improve the identification of redundant files, we applied the […]

Guiding style harmony in the Accompaniment Machine

When performing a piece using styles on a keyboard, the function of the left hand is to signal the harmony applied to the style notes.
