New Features In Software Version 1.2 - Korg Oasys Operation Manual

Quick Start
New features in software version 1.2
OASYS software version 1.2 adds a number of new
features, including increased polyphony for the AL‐1
and STR‐1, polyphonic unison, unison stereo spread,
improved parameter smoothing, and a powerful and
easy‐to‐use chord feature. It also includes a demo of
the new Legacy Analog option, which can be enabled
via an authorization code purchased from
www.korguser.net.
New EXi option: Legacy Analog
The Legacy Analog collection for OASYS features
enhanced versions of two classic Korg analog synths,
using Korg's proprietary CMT (Component Modeling
Technology): the MS‐20EX and PolysixEX.
Much more than simple re‐creations of their acclaimed
vintage predecessors, however, these EXi take their
concepts to the next level–with many new features
unique to the OASYS.
Demo mode and authorization
A demo version of the Legacy Analog collection is
installed with OASYS software version 1.2, and new
Programs using the MS‐20EX and PolysixEX are
loaded into Bank USER‐D.
In demo mode, you can play, edit, and save Programs,
Combis, and Songs which use the new EXi–but until
you purchase an authorization code, their sound will
fade out periodically.
To purchase an authorization code, and to download
additional, free banks of Legacy Analog sounds, go to
www.korguser.net. Once purchased, you can enter the
authorization code on the new Plug‐In Info page in
Global mode.
For more information, see "Global P6: Plug‐in Info" on
page 738 of the Parameter Guide.
MS-20EX
The MS‐20EX is a flexible, semi‐modular virtual analog
synthesizer. At its heart is a faithful re‐creation of the
original Korg MS‐20, including both its many features
and its distinctive, often aggressive timbral signature.
To this core, we added all of the features first
introduced in the Korg Legacy MS‐20 plug‐in, such as
the External Modulation routings, tempo
synchronization, and the Analog knob, for modeling
the inherent instabilities of analog oscillators and
filters.
Then, we made significant, OASYS‐only modifications
to the Patch Panel, inspired by the MS‐20's big brother,
the MS‐50. These enable discrete access to all major
components, including both VCOs, the HPF, LPF,
VCA, and the ESP's Band Pass Filter, for more
powerful patching capabilities.
The Patch Panel itself is also more flexible, with two
new mixers for merging and scaling signals, and
unlimited "mults," so that each output can be
connected to multiple inputs. Like the original MS‐20,
you can also use a live audio input as both an audio
and control source.

Finally, we added AMS modulation for all original MS‐
20 controls, plus four additional EGs, four additional
LFOs, and four AMS mixers. Of course, the MS‐20EX
has access to all standard EXi Program features,
including dual key tracking generators, the Common
LFO and Common Step Sequencer, Vector, KARMA,
EQ, and effects.
For more information, see "EXi: MS‐20EX" on page 285
of the Parameter Guide.
PolysixEX
The PolysixEX is a rich‐sounding, easy‐to‐use virtual
analog synth. It also features very high polyphony–up
to 172 voices, with room for effects!
When designing the PolysixEX, we started with a
faithful reproduction of the features and sonic
character of the classic Korg Polysix. These include a
VCO and sub‐oscillator, pulse‐width modulation with
a dedicated LFO, a four‐pole, self‐oscillating resonant
lowpass filter, an ADSR envelope, a Modulation
Generator (aka LFO), an integrated arpeggiator, and
built‐in effects.
Next, as with the MS‐20EX, we added the features
from the Korg Legacy Polysix, including External
Modulation routings, tempo synchronization, and the
Analog control.
Finally, we added AMS modulation for all original
Polysix knobs and switches, plus two additional EGs,
two additional LFOs, and four AMS mixers.
Of course, the PolysixEX has access to all standard EXi
Program features, including dual key tracking
generators, the Common LFO and Common Step
Sequencer, Vector, KARMA, EQ, and effects.
These additional features open up expressive and
timbral possibilities far beyond the original
instrument–and yet all of the main synthesis
parameters fit onto a single page of the display.
Together, these make the PolysixEX a perfect
combination of simplicity, great sound, and versatility.
For more information, see "EXi: PolysixEX" on
page 313 of the Parameter Guide.
What is CMT?
Korg's CMT (Component Modeling Technology)
creates virtual instruments that are indistinguishable
from the original. CMT takes an organic approach to
modeling, reproducing not only the sound but also the
character and response curve of each parameter, so
that the results are completely faithful to the original
model.
CMT's cloning of the entire instrument, based on an
intimate knowledge of the original analog circuits,
ensures that every nuance is replicated–delivering all
the power and subtlety that up until now only true
analog synthesis could provide.
