The "drums" on Oxygene V was made with the RMI Harmonic Synthesizer. It can be recreated with any synth today that has got a noise generator. But I can't help you (no synths...

).
Some of the rhythms from the Korg Minipops 7 can be found here:
http://www.bluesynths.com. You have to register but it's free and worth it if you like old vintage synths.

If you're happy with samples from it then you can find that here:

I'm still waiting for somebody to make some rex-files of the patterns in Minipops 7. But I guess that it's a pretty time consuming job. Sad...because I don't want to hunt down and buy a real Minipops 7 (no clock in - no midi. Collector's item=too expensive).
