Definitely read the manual and read here and read on the FL forums for everything about midi and audio over usb. I have moved to Bitwig Studio and currently playing with Renoise. All of them are great tools. Some strengths and weaknesses to each.
Here is a thread we started when OB was in beta and there wasn’t a lot of FL specific information. Hopefully it will put you on the right path.
