Hi,
Nice one! Mine has been done with an ARP2600-V. Square (44% 8") + Saw 16" and sound more "squary" has yours!
Now for the sparkling sound (upper arpegio) who appears after 30 seconds i used a second ARP2600 4" OSC but i'm questionning about this sound. It is possible that Jarre used an aux channel with the same main arpegios thru a phaser and octave shiffting? Same questionning about loud kick (1:37) who seems following the rythm of the bass sound. Passing the sound also on a aux channel with EQ (low pass) to get only a loud kick like sound.
Which sound is used for flute part (1:45') who has the same notes has bass sequence? I used a flute sample from CMI with and differed sample start. Sounds good!
That for at the moment my instrument list after creating the first part (2 firsts minutes).
Bass sequence: ARP2600-V
Main solo: Vaacum (Air)
Kick: Linn Drum Samples
Snare: Linn Drum Samples
Low Kick (from 1:37): KR-55
Hi-Hats (Phased): Linn Durm Samples
Hi-Hats: Linn Drum Samples
Sparkling Arpegios: ARP2600-V
Claps: Linn Drum
Clave: Fairlight Sample +1 tune
Flutty Melody: Fairlight Sample
Now i'm working on second sequence sound (1:55) who seems to be a plucked sound...
