Well, since you already have a computer program, why not just get an XP30 instead.

This board goes for $999 or as low as $799 at most stores and alread has three expansion boards pre-installed. Out of the box, you already have near 1600 sounds.

Furthermore, it can be expanded with two more expansion boards. You should get the Vintage Synth SR-JV80-04 board. This has lots of synthetic sounds that are reminiscent of Jarre. When you add those two up, you shouldn't have put down more than $950-$1100.

Look on Ebay for better deals. I hope I've helped.
