Ensnareyou,
I was 'a little bit' ironic when compared the price of Oasys to the price of studio. Of course it wasn't that much expensive, but still it was really expensive.
For 8.000,00 USD you could buy 3-4 different top-of-the-line synths that cover most of the Oasys sonic capabilities (although Karma engine would still be missing).
Also, for that amount of money you could buy PC/laptop with enough software (sequencer,VSTi...) to rival Oasys (again without Karma).
As for the expectation to have DAW capabilities on keyboard to match DAW capabilities of studio equipment (or even software DAW) I doubt it will happen soon. Big screen, computer keyboard and the mouse combined with good MIDI/DAW controller are much easier to use then anything a synth keyboard could offer.
I'am not saying that Oasys was bad product, it was really great keyboard, but they should have stick to the Karma and different sound engines, and throw out everything that doesn't belong to the keyboard.
