Just for those with a short memory, seriously claiming that the Oasys plays remotely in the same league as the Kronos:
This is what the Kronos has over the Oasys:
- new Piano-Engine with 2x Gb-Premium-Pianos (plus many more high quality pianos available only for the Kronos)
- new EPiano-Engine with 5 different Rhodes/Wurly models
- updated: new B3 engine vastly superior over the old one
- SSD-drive for fast streaming (no mechanical harddisk dangers)
- signifcantly stronger processor
- smooth sound transition across all modes:
- setlist-function
- many new programs / combis: not just from the new Engines, but also 7 full HD-1 banks (128 patches each) compared to 5 in the Oasys, and lots of additional banks not present in the Oasys for user patches
- drum Track feature with possibility to add 1000 user drum patterns
- 75 drumkits compared to 40 in the Oasys; including new high quality mega-drumkits
- sample-comparison of factory-content: Oasys: 3,518 drum multisamples from dem standard ROM, EXs1 mono and EXs1 stereo; Kronos: 7,000 drum multisamples from Standard ROM, EXs1 ROM expansion 1 in stereo, EXs5 ROM Expansion 2, EXs8 - Rock Ambience Drums, und EXs9 - Jazz Ambience Drums.
- higher sequencer resolution
- 24-bit audio-recording (Oasys 16-Bit)
- lots of choices from additional sound libraries, among them many first class libraries which are not available for the Oasys
- since OS 2: user sample streaming (which is a revolution for the use of big user libraries). That allows getting virtually any sample instrument sound in high quality into your Kronos, whatever you want and need.
- since OS 2: second SSD allowing to have a) lots of data plus any kind of backups directly on board for super fast access
- despite all the better specs: much easier to carry
- since last update: fast split mode
I'm not even sure I mentioned everything.
All in all, that's two completely different instruments, for anyone knowing how to use a powerful workstation live. For live purposes, the Kronos has developed miles ahead of the Oasys. Calling that "cosmetic" is nothing but unwillingly funny from my view.
Concerning the so called "death of workstations": "Workstation" is just a name for something you can use live in a specialized way for your musical purposes: in a melting of soft- and hardware, which you just don't get from your casual notebook, nor from any simpler synth or performance keyboard. The definition of "workstation" will surely change with developing hard- and software, but the underlying idea is as much alive as it ever could be.
Jan1 is completely right: the workstation concept has just expanded, in sharp contrast to dying, and reached the drum box market, where it will be extremely sought after by DJs and performers as long as the software in it works well.
I don't think Korg will present a new workstation 2017. But they could advance the Kronos as much with new hard- and software, as the Kronos is ahead of the Oasys, if they wish to do so - anytime. For the moment, they do not even have a Kronos competitor - after 6 years!
