Lite nyare info om OASYS från Dan Philips (yahoo-group):
Speaking as someone who has worked on all three OASYS projects, I'm
pretty clear that the new OASYS is a step forward in many respects.
Here's some related info, arranged as FAQ questions and answers:
* What makes OASYS ?Open??
The synthesis and effects processing of OASYS is based on software, and
not on fixed-purpose, dedicated hardware. This is the reason that
OASYS can dynamically allocate between all of its synth models
(currently, the HD-1, Al-1, and CX-3), and if desired use all of the
system's power to play a particular model - unlike
expansion-board-based systems, which typically offer a fixed, limited
number of voices for each synthesis type.
This software-based architecture also allows you to make your own
trade-offs between the power allocated to playing synth voices, and
the power allocated to effects.
Because all synths and effects are software-based, Korg will be able to
expand these capabilities via software - without adding any additional
hardware (no EXB boards necessary, for instance). Future EXi
instruments and EXf effects should keep OASYS sounding fresh and
cutting-edge for many years to come. You can also expand sample
libraries via EXs , as well as by importing Akai, WAVE, or AIFF data.
* This product seems a little different from the unreleased, mid-1990's
OASYS keyboard, and from OASYS PCI. Why are you calling it OASYS?
All three OASYS products (so far!) have had differences from one
another, but they also all share the same, core ideas: expandable
software-based synthesis, physical modeling, and exceptional audio
quality.
OASYS offers a number of important advancements over OASYS PCI,
including significant improvements to the synthesis algorithms, greatly
increased number of voices, and dynamic voice allocation. It doesn't
currently have as many different synthesis algorithms as OASYS PCI -
but that's what EXi are for.
* Is this the original OASYS design from the mid-1990?s?
No. Although it's based on the same core ideas as the original OASYS
keyboard (see above), the 2005-model OASYS uses an entirely new
architecture. In comparison to the original, the new OASYS offers
significant improvements to the synthesis algorithms, polyphony, and
future expandability.
* Does OASYS support SynthKit, like the OASYS PCI?
Not currently.
* Are there third-party EXi, EXf, or EXs for OASYS?
Not currently, but we're very open to that possibility.
* Is it possible that future EX i will play samples, or are EX i just
for "modeling?"
Yes, it?s possible that future EXi would include sample-playback.
* Are EXi , EXf , and EXs expansions hardware boards, like the Triton
EXB series?
No. They are software and data, loaded onto the internal hard drive.
This is designed to allow easy future expansion of EX i , EX f , and
EX s via software (e.g., CD-ROMs, web downloads etc.).

When it's released, listen to the OASYS synth sounds, and compare them
to anything else on the market, hardware or software. If you don't
think that it sounds better, then you probably don't need it in your
studio. And if I didn't think it *did* sound better, I probably
wouldn't be suggesting this!

Most sample playback, both hardware and software, suffers either from
aliasing, from poor high-frequency response (from attempts to
ameliorate aliasing), or both. OASYS uses extremely high-quality
interpolation to minimize these common problems.
In other words - not all sample players sound the same.

We've announced that, relatively soon, we'll be upgrading the OASYS
software to support up to 1.5 GB of sample RAM.
