To map unpitched percussion in MuseScore Studio on Mac, choose the playback sound first, then configure staff positions and input shortcuts with Customize kit. Test the sound, notation, and linked part separately before entering a full passage.

This guide covers one task: setting up an unpitched percussion staff so each input produces the intended notation and playback. Pitched percussion follows ordinary note entry. The current handbook describes the drum-pad interface introduced in Studio 4.5; older instructions may show a different panel. Inputting percussion notation, MuseScore Studio 4.5 is now available!

Identify which mapping needs to change

Use this decision aid before editing. It separates the controls you need for each result, based on the handbook’s descriptions of the percussion panel, kit editor, and mixer.

Desired result Control to inspect
Put a pad somewhere easier to reach Percussion panel: Layout, then Edit layout
Enter an instrument with a computer key Pad options: Define keyboard shortcut
Change a sub-instrument’s staff position or notehead Customize kit
Choose the staff’s playback library or sound Mixer: Sound
Find the MIDI key for an available percussion sound MIDI assignment displayed on its pad

For example, suppose a snare sounds correct but you want its notation lower on the staff. Start with its notation settings. If the written rhythm looks correct but the whole kit uses the wrong playback sound, start in the mixer. This diagnostic order follows the documented separation between notation customization and sound selection.

Choose the playback sound before configuring input

Open View → Mixer. Find the percussion instrument’s channel and inspect its Sound row. To change it, hover over the displayed sound name, click the dropdown, and select the required entry. The mixer supports SoundFonts, MuseSounds, and virtual instruments; changing a sound here does not change the instrument’s staff notation. Mixer

Select a note or rest on the unpitched percussion staff to display its percussion panel. Switch to Preview and click the relevant pads to audition them without adding notation. Return to Write afterward. Available sub-instruments, variants, and displayed MIDI assignments depend on the selected sound library, so check these again after changing it. Inputting percussion notation

If the staff is silent, inspect the channel’s Mute, Solo, and volume controls before rebuilding its notation. A soloed channel silences other channels; a muted percussion channel cannot be diagnosed by moving noteheads. Mixer

What if the required sound is missing?

The handbook permits customized combinations of unpitched sub-instruments but explicitly warns that playback support may be unavailable. An added notation definition therefore needs a separate listening check. Begin with a documented combination instrument—such as a drum kit, mixed percussion, or General MIDI percussion—that provides the required sounds in the chosen library. Inputting percussion notation

The documented Customize kit controls cover notation and shortcuts; they do not establish an arbitrary sample-remapping command. For this workflow, use an available sound and configure its notation, or choose a suitable playback library through the mixer. Do not assume that renaming a pad supplies a new sound.

Set staff positions, noteheads, voices, and shortcuts

Click Customize kit in the percussion panel header. Select the required sub-instrument or variant in the left-hand list. Use its name and MIDI-number columns to identify the entry before making changes. Percussion kit customization

  1. Adjust Stave line with its arrows to change the displayed line or space.
  2. Choose a Notehead group for the required appearance.
  3. Set Default voice and Stem direction for subsequent entry.
  4. Inspect the preview and score, then click OK to commit.

Changes to default voice and stem direction affect future notation; they do not revise existing notes. Percussion kit customization

For a computer-key assignment, click the pad’s bottom grey options area and choose Define keyboard shortcut. Assign a convenient key and resolve any conflict prompt. To reorganize the panel itself, choose Layout → Edit layout, drag pads into position, then click Finish editing. Inputting percussion notation, Customizing the percussion panel

Moving a pad changes its panel position. Use Layout → Notation preview when you want to compare pads by their written appearance; hover over a pad to identify its instrument or variant. This display choice is saved with the score and applies across its unpitched percussion instruments. Customizing the percussion panel

Verify computer, mouse, and MIDI input

For a controlled test, use the default Input by note name mode. Select a starting rest, press N, and choose a duration in the toolbar. Confirm the input cursor is at the intended beat. Exit with Esc when finished; on Mac, Cmd+Z undoes an unwanted entry. In Input by duration mode, the selection order changes: choose pitch before duration. Entering notes and rests

Test one entry with a pad or its assigned shortcut. Then test mouse entry directly on the staff. While hovering, hold Shift to display instrument labels; where variant arrows appear, use them to select among variants sharing that staff position. Inputting percussion notation

For an external controller, open preferences with Cmd+, and inspect Audio & MIDI for the input-device settings. The separate MIDI mappings section assigns controller keys to application actions, such as playback or duration selection. Its documented purpose does not establish a general drum-note remapper. Preferences

Use the MIDI assignment displayed on the percussion pad when testing controller entry. If a computer shortcut works but a controller key selects another sound, compare the incoming key with that assignment before changing the notation definition. The handbook states that these assignments depend on the selected sound library. Inputting percussion notation

Keep written pitch and sounding pitch separate

For transposing pitched instruments, written pitch is the notated pitch; sounding or concert pitch is what is heard. MuseScore Studio normally displays written pitch, with a Concert pitch checkbox in the status bar for changing the view. Transposition

Studio 4.5 introduced an option to interpret MIDI input as written or sounding pitch for transposing instruments. That option addresses pitched transposition. For this unpitched percussion task, use the pad’s sound assignment and staff mapping; do not use concert-pitch display as a substitute for configuring percussion notation. MuseScore Studio 4.5 is now available!, Transposition

Check linked parts before reusing the setup

Open Parts, select the percussion part, and click Open selected. Content changes—including adding or deleting notes and changing their pitches or durations—propagate between score and parts. Correcting a percussion passage inside a linked part therefore affects the shared music. Parts

Appearance has separate synchronization rules. Item-property changes made in a part can become desynchronized from the score; score-side changes propagate unless the corresponding item is already desynchronized. Inspect Properties → Score and part synchronisation when an individual item differs. These documented item controls should not be treated as proof that an entire percussion-kit definition is independent in each part. Parts

If expected notes are absent from a custom part, check its voice visibility. In the part’s Layout panel, expand the instrument, open the staff settings, and inspect Voices visible in the score. This is particularly useful after planning percussion entry across multiple voices. Parts

Save the kit and perform a short acceptance test

Save reusable customizations through Customize kit → Save as..., creating a .drm file. Load it through Load... in the kit dialog. Use a matching instrument and the correct mixer library: the handbook warns that loading a drumset file onto another unpitched instrument does not ensure correct playback. Percussion kit customization

For a practical acceptance test, enter a short illustrative passage containing one note from each sound you intend to use. Check each input method you actually need, inspect the written positions and voices, listen to playback, and open the linked part. Record any mismatch as an input, notation, playback, or part-display problem, then revisit the corresponding control above.

Keep version differences in mind when following screenshots. The pad interface began in 4.5, while adjustable percussion-panel column counts arrived in 4.6. The handbook also documents a Use legacy percussion panel option under percussion preferences. MuseScore Studio 4.5 is now available!, MuseScore Studio 4.6 is now available!, Customizing the percussion panel

Once the short passage enters correctly, looks right in both score and part, and plays the intended sounds, use that verified setup for the remaining music. Keeping those checks separate makes later corrections easier to locate and avoids rebuilding a working mapping unnecessarily.
