To use a MIDI keyboard in MuseScore Studio, connect and power it on, select a score position, enter note input mode, choose a note duration, then press keys on the controller. If the keys do nothing, check that MuseScore Studio is using the correct MIDI input device and that note input is active.
Connect the keyboard and enter notes
- Connect and power on the keyboard. Use its USB connection if available. If it has traditional round MIDI ports, it may need a MIDI-to-USB interface or adapter, depending on the ports available on the keyboard and computer.
- Open MuseScore Studio and a score. For an initial detection check, turn on the keyboard before launching MuseScore Studio. This startup order appears in older handbook guidance; it is a sensible first check, not a guaranteed requirement on every current system.
- Select the score location where you want the notes to begin.
- Start note input mode and choose a duration using the toolbar or its shortcut.
- Press keys on the MIDI keyboard to enter pitches. The MuseScore Studio Handbook’s note-entry instructions explain that MIDI keys enter notes while note input mode is active.
Release each key fully before pressing the next to enter consecutive notes. To enter a chord, press the desired keys together. Notes outside the score’s key signature receive accidentals automatically, though you may need to correct their enharmonic spelling.
Choose the MIDI input device if MuseScore does not respond
When more than one MIDI device is available—or the keyboard is not responding—check MuseScore Studio’s preferences under Audio & MIDI and select the keyboard as the MIDI input device. The preferences handbook page also covers MIDI mappings and note-input behavior. Menu details can vary by version, so use the current Audio & MIDI section rather than relying on older instructions that name different menus.

Troubleshoot by symptom
The keyboard is not listed
- Check that the keyboard is powered on and connected, and confirm that the operating system recognizes the keyboard or MIDI interface.
- Reconnect the device or power-cycle it, then reopen MuseScore Studio. Starting MuseScore after the keyboard is on is also worth trying, but older handbook guidance does not establish this as a universal fix for current versions.
- If the keyboard has round MIDI ports, verify that the interface or adapter matches the connections on both the keyboard and computer. An adapter is not needed for every setup.
The keyboard is listed, but pressing keys does not write notes
- Select a position in the score, activate note input mode, and choose a duration before pressing keys.
- Confirm that the keyboard—not another available MIDI device—is selected as the input in Audio & MIDI preferences.
The keyboard makes sound, but no notation appears
Sound output and MIDI note input are separate functions. A keyboard producing sound does not by itself confirm that MuseScore Studio is receiving it as a note-entry device. Check the input-device selection and the score’s note-entry state.

Only one note appears when you intend to enter a chord
Press the chord’s keys at the same time. Fully releasing one key before pressing another tells MuseScore Studio to enter consecutive notes instead.
Use the on-screen piano to test note entry
MuseScore Studio’s built-in piano keyboard lets you select pitches without an external controller. Open it through View → Piano keyboard or press P. If notes entered this way work but the external keyboard does not, focus troubleshooting on the MIDI connection and selected input device.

Step-time or real-time entry?
For most users, ordinary note input is the straightforward starting point: choose a score position and duration, then enter pitches one at a time or as chords. MuseScore Studio also offers real-time modes for performing notes into the score. The modes differ in how much rhythmic interpretation is needed and in their notation constraints.

| Entry method | How it works | Important limits |
|---|---|---|
| Ordinary note input (step-time) | Choose a duration, then enter a pitch or chord at the selected score position. | Notes may replace notes at the selected position depending on the mode and score context; save before experimenting with unfamiliar methods. |
| Real-time entry | Perform on the MIDI keyboard while MuseScore Studio adds notation. | Preselect the shortest duration you will use. Tuplets are not supported, and entry operates on one staff and one voice. |
See the handbook’s note input modes page for details on real-time options and their constraints.
