Quick Start New features in software version 1.1

Increased polyphony for the AL-1 & STR-1
As part of our continued refinements to the OASYS
system, you can now play more voices of the AL-1 and
STR-1!
The updated AL-1 is capable of playing 96 voices (up
from 84), and the STR-1’s max polyphony is now 48
voices (up from 32–a factor of 50%). Naturally, the full
audio fidelity of the previous versions has been
preserved.
Unison enhancements
Unison has been improved in several ways, for both
HD-1 and EXi Programs. To begin with, you can now
enable unison in Poly mode, as well as in Mono. The
new Unison Stereo Spread parameter distributes
unison voices across the stereo field, for a more intense
effect. Finally, the range of Unison Detune has been
doubled, to a total width of 200 cents (100 cents up and
down).
For more information, see “Unison” on page 34 of the
Parameter Guide.
Max # of Notes
The new Max # of Notes parameter lets you model the
voice-leading of vintage synthesizers, such as the
Polysix, as well as control the resources required by
individual Programs in Combination and Sequencer
modes. Max # of Notes is available in both HD-1 and
EXi Programs, as well as for each Timbre in a Combi
and each Track in a Song.
For more information, see “Max # of Notes” on
page 33 of the Parameter Guide.
Improved parameter smoothing
Since its initial release, OASYS has used several
different smoothing processes to minimize
“steppiness” on knobs, sliders, and controls. These
processes have been further improved, via a new
adaptive smoothing algorithm.
Tone Adjust is now smoothed as well, so that you can
use this Control Surface mode for performance as well
as editing. Many parameters are also now smoothed
even when edited from the LCD.
Chord mode
The original Polysix had a fun, cool Chord function,
which let you store a chord and then transpose it by
playing single notes on the keyboard. We thought this
was such a good idea that we integrated it throughout
the OASYS system. You can now enable Chord mode
for any HD-1 or EXi Program, as well as for each
Timbre in a Combi and each Track in a Song.
Chord mode is integrated with the Drum/Chord Pads.
Just as before, you can store up to 8-note chords for
each Pad–but now, with Chord mode, you can use the
pads to select a chord, and then play it from the
keyboard.
A new Chord SW function lets you enable and disable
Chord mode from SW1, SW2, or the Assignable Foot
Switch.
Chord mode can duplicate the way that the Polysix
chords worked, but it can also use all of the Voice
Assign options to create different effects–such as mono
legato chords with fingered portamento, or poly
chords that overlap one another.
For more information, see “Using Chord mode” on
page 49, and “Chord” on page 34 of the Parameter
Guide.
New features in software version 1.1
OASYS software version 1.1 added a number of new
features, including the STR-1 Plucked String EXi,
support for up to 2GB of RAM, a new AMS Mixer type,
and more.
New EXi: STR-1 Plucked String
As the first EXi update for OASYS, the STR-1 Plucked
String advances the state of the art in physical
modeling, building on over a decade of Korg’s research
with new innovations exclusive to OASYS. It offers a
comprehensive and sophisticated set of synthesis tools,
capable of creating both traditional sounds (acoustic
and electric guitars and basses, clavinets and
harpsichords, harps, bells, electric pianos, ethnic
instruments, etc.) and unique, experimental timbres.
For more information, see “EXi: STR-1 Plucked String”
on page 235 of the Parameter Guide.
Support for up to 2 GB of RAM
OASYS now supports up to 2 gigabytes of RAM,
which can be used for RAM and EXs samples. Among
other things, this means that you may now load both
EXs1 and EXs2 at the same time, if desired.
For more information, see “Installing memory” on
page 1038 of the Parameter Guide, “Expansion Sample
Setup” on page 684, and “Sampling and RAM” on
page 563 of the Parameter Guide.
Supported DRAM DIMM modules
The OASYS has two DIMM sockets. One slot is
occupied by factory-installed memory; the other is left
open for user expansion.
Some commercially-available memory will not
work with the OASYS. The following types of
memory are supported.
Specifications: 184-pin DIMM DDR SDRAM,
unbuffered, non-ECC
