I know exactly where you go that melody from...

Lets see here, its from the fl studio tutorial (basics on techno) video from youtube. I used that same video to learn about FL Studio two years ago. I haven't really worked on songs seriously but its a good place to start. Keep working on songs until you've got the program down. Right now it seems like the patterns don't flow all that well, there are interruptions quite often. I'd suggest looking up more tutorials or exploring the program a bit more. That helped me A LOT. Best of luck to you :) and I need to say its better than anything I could make at first hehe.
