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 […]

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 […]

The right accompaniment can enhance your vocal, instrumental or keyboard performance. Accompaniments are also a great way to practice.

On the other hand, sometimes you may want to use a full MIDI file to accompany an iconic song, complete with […]

The quantity Note takes integer values from &h00 (0) to &h7F (127) following the chromatic scale. Middle C corresponds to Note = &h3C (60). Therefore, a transposition of […]

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 […]

Manually creating a new file type in Windows

File types in Windows are designated by extensions (e.g., .txt, .html, .jpg, …). You can associate a file type with a specific program. Then, if you double-click on a file in MIDI File Manager or Windows Explorer, the file opens in the associated program. For example, my computer is set up to open files of […]

MIDI File Organizer: new feature

MIDI File Organizer is one of the components of our MIDI Utility Pack. In addition to organizing and previewing your MIDI file, the program provides an effective method to organize data on your disks. The idea was to incrementally add all the features I ever wanted in a file manager. For example:

A clear and […]
