Hi. In Hokusai, I have figured how to import a file to work on and cut a smaller part out of a bigger file and export the cut part, but I can not figure out how to do much else. When I tried to join files together, they played all at the same time instead of one after the other? How do I make them play one after the other and how do I insert blank parts so there is a gap in play between tracks? How do I pick how long that gap is? Also, I also did the full in-app upgrade for $10 to get all the effects and filters and stuff, but I can not figure out how to apply any of the filters or effects. I know Hokusai has an in-app user guide and I read the whole thing twice and am still stuck. Help please? Thank you.
