That synth is a Korg T3 that Perrier is playing,Its almost identical in looks and sound to the M1 except for the larger screen and a few more buttons,and a little more extra PCM data
I used to own one of those,Jarre used a sound off the presets called "Waterphone/shellphone" during the PLD concert it was the sound used on the Atmospheric intro on Zoolookologie,and
Magnetic fields 2 Intro (The sound is the stepping down sound or Arabic type loop in the background)that is a staple sound in all the Korg Ai2 Synth banks PCM data not entirely sure if he used any presets on the WFC albumfrom the T3,never found anything in the Banks that he maybe used that was obvious
He could have perhaps had a prototype of the K2000,he did an interview for Sound on Sound magazine early 90s,where he said he was helping Kurzweil to develop one of there sampling operating systems,so could have been the K2000,although the actual street release of the K was 1991,it is possible Jarre could have had a preproduction model,as for Wikipedia,don't take everything on there as concrete fact,its so full of fabricated facts due to the way in which the data is compiled...
As for the Chrono 6 bass,I would say it was definetly a Moog device,the sound is distinctive of a Moog timbre and I've emulated the sound on the Voyager,although I would say Jarres has been doubled up or processed either with compression or another synth to give it more bottom end,he most certainly used the Midimoog rack on the Album.
