Vigier Guitars

Hello all,
I have bought a Vigier sixstring bass today (second hand) and upon arrival at home, I thought that it might very well be an Arpege instead of the Passion I was expecting (the information in the ad was very brief, and the photographs not too great either). After some digging, it became clear that it was an Arpege indeed!
Now, being the engineer that I am, what exactly do the different presets do?
Here is a picture with the new sixstring, and the fiver I've a long long time ago

Best regards,
Jarno.
 

So, not a lot of bassplayers around here? Nobody with an Arpege bassguitar, who knows what the presets do?
Patrice?
Best regards,
