IBM PS1500 Stereo Amplifier User Manual


 
Basic concepts 3•5
when you play PS1500 as a stand-alone unit.
Selecting Sounds and Presets via MIDI is dis-
cussed in a later chapter.
TRACKS
A Track is the smallest part of a Preset. Pro-
grammable Presets have up to 3 tracks (for the
keyboard), Style-Presets have a maximum of 8
tracks (3 tracks for the keyboard and 5 engaged
by the sequencer for the accompaniments). A
Song-Preset can contain up to 16 tracks.
A Preset is a configuration of several tracks, so
that different Sounds can be combined to play at
the same time. In Style/Preset and Song/Style
modes, the Sound names of the keyboard tracks
appear in the main display. In Song mode, the
Sounds of all the tracks appear in the form of a
ProgramChange number. Sometimes, a track is
not assigned to a PS Sound, but it controls an
expander connected to the MIDI OUT. In this
case, the relative ProgramChange is shown on
the main display.
In the first page of «Edit Preset», it is possible to
see the sounds assigned to all the tracks of the
current Preset in the form of a ProgramChange
number. For the selected track, the correspond-
ing Sound name and Bank number is also shown
on the top line of the display. The Tracks are
shown from 01-08 and from 09-16. The Track
Select button in the 16 Track Recording Studio
section allows you to switch from the track set
01-08 to 09-16.
Most of the operating modes display the tracks
which can be selected and can be programmed
for Sound assignments, a transposition, an effect
selection or a performance control.
The status of the keyboard tracks (active or mute)
can be changed by intervening directly on the
corresponding keyboard activators (Upper 1, Up-
per 2 and Lower), or Function buttons F8, F7 and
Tracks/Sounds
F4/F5 respectively. The active/mute status of all
other tracks (Styles, Song/Style and Songs) is
changed by direct intervention on the correspond-
ing track buttons of the sequencer.
SOUNDS
PS1500 Sounds are divided in four different
types:
• ROM-Sounds
• E-Sounds (edited ROM-Sounds)
• Drumkits
• Samples
Rom-Sound
Sounds contained in ROM. These sounds are
permanent and cannot be cancelled. They are
based on the internal samples archive (ROM-
Waves)
E-Sound
E-Sounds are created by modifying ROM-Sounds
or by loading the data from disk (loading Presets
containing E-Sounds). A Preset can store up to
8 E-Sounds and it can be programmed to recall
E-Sounds or the original sounds.
Drumkit
Drumkits assign a different percussive sound to
each note of the keyboard.
A Preset can store up to 4 modified percussive
sounds of a Drumkit. PS1500 contains 16 Drum-
kits memorized in Banks 2 and 3 of the Percus-
sive Sound Groups.
Samples
The PS1500 on-board sampler can capture a
Sample which is stored in location 8 of the Sam-
ple-RAM.
PS1500 Sample kits are also available to load
