Dude, have you read the manual and the tutorial booklet. They're pretty good. I made a tutorial ages ago for doing a nice lead. Don't know if it's still around, it was a long time ago.

Start with a simple lead.

Run osc 1 as a saw, osc 2 as saw or square. Turn unison up to like 3 or 4. Turn sub osc up to half. Add some pulse width modulation, a bit of noise, some reverv/delay, bit of chorus. Set the filter envelopes to determine if you want a lead or a pluck sound.

I really suggest you try reading the manual though. Another great way is to pull up patches on sounddiver and see all the parameters and how those patches are created.

That and you should probably try learning a little bit about synthesis I mean you just bought a nice piece of hardware right there and you don't know how to use it? Try to get some knowledge on synthesis and check out people's patches and develop your skills from there and you'll be making above and beyond leads, pads and the like in...a year? ;P I dunno good luck though
