Building a style library

Styles are MIDI loops included on digital keyboards from Yamaha and other manufacturers from which you can build automatic accompaniments. The feature, which makes a good approximation to a backup band, can turn a simple tune into an interesting performance piece. Yamaha-format styles form the core of our program, the Accompaniment Machine. A typical keyboard […]

PureStyle file format reference

Styles are the versatile automatic accompaniments found on digital keyboards from Yamaha and other manufacturers. There are thousands of Yamaha-format style files available for purchase or download on the Internet. Styles are employed to create custom accompaniments — a virtual backup band for performances. Styles may be installed on keyboards or used in computer programs […]

Tempo corrections in Style Customizer

I added a new feature to the Style Customizer in response to a problem I encountered creating an accompaniment to Memory by Andrew Lloyd Weber. The piece is in 12/8 time and there are few, if any, Yamaha-format styles available with this time signature. On the other hand, there are many available styles in 3/4 […]

Style Customizer: bulk style corrections

Styles are the automatic accompaniments available on digital keyboard from Yamaha and other manufacturers. They function like a backup band to spice up performances. The Yamaha-style format has become the de facto standard for style exchange. There are more than a hundred-thousand style files available for download or purchase in all musical genres. Unfortunately, the […]

Fixing percussion sounds with Style Customizer

Yamaha-format styles are accompaniment files that you can play on your digital keyboard or use in our Accompaniment Machine program. Often, you may find a great style that is effectively useless because 1) it’s permeated by police whistles and other strange sounds or 2) the percussion sounds like someone pounding on a piano . In […]

FreeStyle: Yamaha-format style improviser for professionals

On January 1 we are releasing a new product, FreeStyle. With it, accomplished keyboardists can improvise sophisticated accompaniments using Yamaha-format style files [1] as MIDI loops. FreeStyle builds on the robust style reproduction engine that we developed for The Accompaniment Machine. Before describing the features of FreeStyle, it’s useful to point out the differences between […]

Converting AMac songs to accompaniments

Users of AMac Versions 1.0 and 2.0 with a library of song files (ASG) probably want to convert some of them to AutoSequence files (ASQ) to use the new capabilities of AMac 3.0. This article describes the conversion process along with some tips on sequences.

To begin, load the song file in the AMac Performance […]

Converting Cakewalk Instrument Definition Files

A user suggested that AMac and SVO[1] would be easier to use if they could read INS[2] files. In this way, the full set of voices for particular keyboard synthesizers would be immediately available for styles and melodies. I analyzed the content of INS files for over 40 keyboards available at http://www.jososoft.dk/yamaha/ins_files.htm. My conclusion was […]

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 […]

It sounds funny

Suppose you have grown tired of the 150 styles that came with your keyboard. You want to expand your options to the 10,000+ styles available on the Internet by using the Accompaniment Machine. You download and try out styles and find that some are strange and that the sound of others is not as good […]
