So many questions, would love to have an "Event" owner answer.

Can I import an "Older" .pat File ?

Correct me if I am wrong..... I can select and replace style elements such as bass, drums, etc , for the style selected ? Is this known as Style Modeling ?

Am I able to select parts of one Style and use it in another Style ?

Is there any software that will help me create a new Style ?
