FL Studio comes in several editions with different levels of functionality. The free trial version includes all of the program's features, all plugins, and allows users to render project audio to WAV, MIDI, MP3, and OGG. Projects saved while in demo mode, however, can only be opened once FL Studio and its plugins have been registered. Also, instrument presets cannot be saved and the audio output of some instruments will cut out momentarily every few minutes until the program and its plugins have been registered.
