Funny things going on...

I've appreciated the folks who have helped me get SD3 going. I'm actually writing drum parts and my songs are beginning to take shape a little.
 
I have a couple more questions: Whenever I open the program or hit "play" I hear a little "TING!" and sometimes at the end I hear it too. I'm sure it's a midi thing, but I don't know how to stop it.
 
Also, for some reason some of the songs I've created, when re-opened, only have the little "TING" sound when I start and stop and the drums don't play. SD3 runs, but no drum sounds come out.
 
Also, why doesn't the SD3 window load patterns from the same place the Step Sequencer does? I'm trying to put a second pattern into my song but I can only drag and drop patterns from SD3, not the Sequencer. In fact, when I open the SD3 window and GO to find those patterns (.ssp) I saved with the Sequencer, SD3 can't even load them at all, so I can't load them into SD3 window. What's up with that?
 
I've figured out how to save different patterns, but I'm not figuring out how to utilize several patterns (verse, chorus, intro, etc.) in the same song. When I open a different pattern in the Sequencer, it changes the pattern on the midi track.
 
Sorry this is so newbie.
 
Anyone? Thanks.
