Need help with Step Sequencer in Session Drummer/Producer

Hi

I have used the step sequencer in Producer to create a drum pattern with Session Drummer.  I can see the pattern in the track.  My question is how do I create a new pattern in the step sequencer to put in the track without losing the pattern already in the track.

Example:

First pattern is:  Bass Drum, Snare, Bass Drum, Bass Drum, Snare (standard rock beat)

Then I'd like to put a new pattern next.... say with some Toms

Can you help me figure out how to use the step sequencer so I can create my drum track?

Thanks
Ryan

Two options:
 
1. Copy-Paste or Ctrl-drag copy the existing step sequencer clip, unlink it from the original, and edit as needed.
2. Click the Step Sequencer button in the the SD3 interface to create a new, empty SS clip in the same track and drag it to where you want it after you've set up the pattern.
 
EDIT: +1 for Fog's recommendation to check out Seth's Drum Production videos.

THANKS - the Master Class Videos are excellent and taught me everything I needed to know and more.  Very pleased with them and would recommend them to anyone with a similar question.  Thanks everyone for pointing me in that direction!
