Using Music Cartridges
■ The Yamaha Style File Format
The Yamaha “Style File Format”, is an original Yamaha auto-accompani-
ment data format which has evolved through years of development and re-
finement of the Standard MIDI File and GM System Level 1 formats on
which it is based. Style File Format makes it possible to provide exception-
ally high-quality accompaniments on many of our instruments, and in the
Music Cartridges used by the PSR-320/420.
Due to the sophisticated accompaniment capabilities provided by Style File
Format, some cartridge styles may have a different number of sections and/
or accompaniment tracks than the internal styles provided by the PSR-320/
420.
● Different Number of Sections
Some cartridge styles, for example, have A and B intro and ending sec-
tions as well as A and B main sections. In such a case, if the [INTRO]
and MAIN [A] buttons are pressed in order to start the accompaniment
with an introduction and then go to the main A section, the intro A sec-
tion will play. If the [INTRO] and MAIN [B] buttons are pressed, the
intro B section will play. A similar situation applies to endings: if the
main A or B section is playing and the [ENDING] button is pressed, the
ending A or B section will play accordingly.
● Different Number of Tracks
While the PSR-320/420 styles have one rhythm, one bass, one chord, one
pad, and one phrase track, some cartridge styles may have two rhythm,
chord, and/or phrase tracks. In such a case these individual tracks can be
selected by moving the cursor from track to track in the normal way. If
the RHYTHM 1 track is selected and the cursor is moved once to the
right, for example, the cursor will not actually move but “RHYTHM 2”
will appear in place of “RHYTHM 1” and the parameters for the
RHYTHM 2 track can be changed as required. The same applies to the
CHORD 1 and 2, and PHRASE 1 and 2 tracks.
