Welcome to the forum.
First of all, Music Creator can only record 2 inputs at a time, so if you want to record more than 2, you'll have to upgrade to SONAR X3 or SONAR Platinum.
Secondly, I think each input in Audio Options is a stereo pair, so you should be able to select Right input for 1 track and left input for track 2. I'm not familiar with the 1010 so I'm not sure if it's set up like that, though. Check it's documentation or just try it.
Good luck!
