Discussion about the Korg PolySix synthesizer

I'm still very confused.
Does the Polysix have one oscillator or six? everywhere I read they 
say it has one VCO (=voltage controlled oscillators) and then the 
next sentence is usually something like "you can stack the 6 
oscillators together for great unison sound".
So what is it then: 1 or 6?
If it is 6, do you have any control on the parameters of the 
individual oscilators? (I know you have it with monopoly - you can 
control the waveshape, tuning etc.)
