The OMF format is a universal file format used to transfer music and audio projects between different digital audio workstations, DAWs. Because most audio editing and mixing programs use their own proprietary format for project files, it is necessary to have a universal format of this type to transfer projects between them. Steinberg's Cubase software contains full support of the OMF file format, which enables you to transfer all of your old projects to a new Cubase installation via the OMF format.
Open the project that you want to transfer using OMF in the DAW in which it was made. For example, if you used Apple's Logic Pro to create the project, open the project in Logic before transferring to make sure everything is set for the OMF format.
Convert any MIDI or software instrument tracks to audio tracks with your software's export feature. The OMF format does not support MIDI or software instruments, so these tracks must be converted prior to transferring. Refer to your software's owner's manual for specific instructions.
Export your project as an OMF project using your software's "Export" feature. For most DAWs, choose "Export" from the "File" menu, then choose OMF under the "Format" drop-down menu. Refer to your owner's manual for specific instructions regarding your program.
Open Cubase, and start a new empty project via the start-up dialogue. From the "File" menu, choose "Import Project." Navigate to the OMF file that you previously exported and click "Import."
Work on your project as usual. As long as you exported your project without any MIDI or software tracks, the entire project, including any separate tracks, their respective effects and VST plugins, will open automatically.
