You can import MIDI loops (file extension .midiloop) in Cubase. These files contain MIDI part information (MIDI notes, controllers, etc.) and all the settings that are saved in instrument track presets. This way, you can reuse instrument patterns in other projects or applications, for example.
Procedure
Result
An instrument track is created, and the instrument part is inserted at the position where you dragged the file. The Inspector reflects all settings that are saved in the MIDI loop, for example, the VST instrument that was used, applied insert effects, track parameters, etc.
You can also drag MIDI loops onto existing instrument or MIDI tracks. However, this only imports the part information. This means that this part only contains the MIDI data (notes, controllers) saved in the MIDI loop, but no Inspector settings or instrument parameters.
