SONG MODE

A Song is sequenced data consisting of one or more tracks (instrumental parts). A Song can be loaded from disk as a PS Song or as a Standard MIDI-file, and it can be recorded one track at a time (multitrack recording).

Up to 16 tracks are available in Song mode. Via MIDI, PS1500 can be also used as a multitim- bral (16 parts) sound generator for Song record- ing with an external sequencer, regardless of the current play mode.

Up to 7 Songs can be stored in the PS1500 song memory. The 8th memory location is reserved for the Chain function which plays back all the Songs in memory as a medley.

PRESETS

A Preset is a combination of sounds (for the key- board, for the accompaniments, for a Song/Style or Song). It also contains the status of the ef- fects, the assignments of the controlling devices (pedals, pads), MIDI channel configuration, track status, Tempo data and the current status of the panel buttons. Selecting a Preset instantly chang- es all the sounds of the tracks and the relative preset settings.

Presets are divided into three types: the Grand- Piano preset, a “single” non-programmable ele- ment, those residing in the PROGRAMMABLE PRESETS which govern the keyboard sounds and those associated to the Styles, Song/Styles and Songs which are recalled by selecting the respective element. With exception of the Grand- Piano Preset, the structure and programming procedures of all are practically identical.

Modes/Presets

Grand Piano preset

The Grand Piano preset, recalled every time you turn PS1500 on, sets the instrument to play as a conventional piano, with the Grand Piano sound active across the full keyboard (assigned to Up- per 1). In addition, the Upper 2 keyboard section is turned off and the Lower section is disabled. The Grand Piano Preset recalls factory settings for the Reverb effect, Volume and Pan and a pre- set panel situation.

Whatever modifications are applied to the Grand Piano preset (reverb effect change, volume change, different sound assignment, etc.) can- not be stored to the Grand Piano Preset, but to the Programmable Presets with the STORE PRE- SET function.

If PS1500 is set to Style/Preset mode, selecting the Grand Piano Preset cancels the current pre- set and substitutes it with Grand Piano. Upper 2 turns off and the Lower section is disabled.

If PS1500 is set to Song or Song/Style mode, recalling the Grand Piano Preset escapes the cur- rent mode and returns the instrument to Style/ Preset mode with Grand Piano active to play on the Upper 1 section in Full mode.

Programmable Presets (Real Time)

64 user-programmable Presets are stored in the eight PROGRAMMABLE PRESETS banks 32 of which are factory-programmed. Presets recall programmed combinations of the keyboard sounds (maximum 3), memorized panel settings and also change the keyboard mode (full or split).

Given that the Presets store the current Style, Variation and Tempo at the moment of activating the STORE PRESET command, the Presets can also be utilized to recall a Style and a Variation. User-programmed Style Presets can be memo- rized to the Presets.
