In the File menu, choose one of: Export Chords…, Export Note Entries…, or Export Notes and Chords…
Choose a filename to use for the exported MIDI file, and choose what you would like to export from the Export popup button.
NOTE: Capo will show a different Export menu item in the File menu depending on whether your song only has notes or chords contained within it. If both are present, you will be given a choice of what to include in the file.
Technical Considerations
Fret and string selections are not preserved in the exported MIDI files.
MIDI files are exported at 60bpm to preserve a 1:1 correlation with the original timescale in the audio file. If you drag the audio file alongside the MIDI data in the DAW, the note and chord entries will be synchronized.
