Aerology Lead I made with a Novation KS5,I've also got a SN rack,but haven't tried a translation as such,but they are pretty similar,I think Jarre used the Mk2,Which has some subtle changes in its architecture,whether he actually used the synth for this track is anyones guess??but is certainly possible to replicate it more than likely because its one of the few synths that have 3 Osc.
Settings:(Relevant to the KS4/5 Rack,although could be applied to the Supernova)

Add some delay FX to suit and add depth.
