The OASYS had vision - ie Open Architecture Synthesis Studio (and how it looked, its build quality and what it did). A vision - doesn't matter whether it happened or not - it was visionary (ie original).
The Kronos? No vision at all. Merely a technical extension of what already existed (and under no stretch of the imagination original) and at a lower price point. Change the game? I don't think so...
What's next? A MicroKronos? Hope not - as again there is no vision. Just capitalisation of a previous vision - at an even lower price point.
So - what's next that's visionary from Korg? Just like can be argued against the others in the big three (Yamaha and Roland), there's nothing visionary to move us music-makers (at what ever level - capability, live or studio, pro or am, etc) to our own relative 'next level'.
What do you think Korg should be doing next? Do we expect Korg to take the visionary lead or what?
(and before the trolls attack - there are amazingly creative machines out there ie Kronos, OASYS, JP-80, Nord, Kurzweil, Fantom, Motif, Virus, etc that could/perhaps should, keep us going for many years. Just appears to me that there's nothing visionary out there just now; or round the corner... just sayin'! - am interested to know what you think ->)
