MIDI keyboard not connecting?
Make sure your keyboard is connected via USB or Bluetooth before opening the app. For USB connections, you may need a USB adapter depending on your device's ports. Check Settings > MIDI to see detected devices.

Crescendo supports MusicXML, MXL (compressed MusicXML), MIDI, and LilyPond files. Use the + button in your library to import files from your device or cloud storage.
