Using Music Cartridges s The Yamaha Style File Format The Yamaha "Style File Format", is an original Yamaha auto-accompaniment data format which has evolved through years of development and refinement of the Standard MIDI File and GM System Level 1 formats on which it is based. Style File Format makes it possible to provide exceptionally 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. q Different Number of Sections Some cartridge styles, for example, have A and B intro and ending sections 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 section 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. q 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. 46
