To close the Import Panel, press the 'X' symbol at the top-left of the panel. If you have made changes to the Import Panel but wish to UNDO them, press Cancel. To reimport the file: Adjust the desired parameters in the Import Panel (see below) and press Apply. The panel can be re-opened at any time during the session by pressing 'Show MIDI import panel' at the bottom of the document window. To accept the default conversion: Simply press the 'X' symbol on the top-left of the Import Panel to close it. If there are multiple tracks, then one more track is added at the top of the list to select all tracks at once. The panel shows all the tracks in the file (only those with note events are shown) and allows you to adjust parameters affecting the conversion process. The MIDI Import Panel appears at the bottom of the screen: you can expand this by dragging the interface with the document window upwards. This converts the MIDI file into a MuseScore file (.mscz) and applies the default quantization settings. To import a MIDI file, use the standard Open command.MuseScore can import MIDI files (.mid/.midi/.kar) and convert them into music notation.
