Basic concepts 3•3
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.
