The Mixer contains controls for adjustments of in-app playback (sound, volume and panning), and MIDI out settings. It contains the Details Area on the top and the Control strips Area below. In between the two is a wide button with a tiny triangle. Clicking on it toggles the visibility of the details area. It uses the Preferences > Score > "Show MIDI controls in the Mixer" as default setting.
To display/hide the mixer, use one of the following:
Expanded parent control, showing child controls in pink.
Displays the Master Gain on the left, and columns of controls on the right. It is important to know the difference between channel and sound track (Musescore Voice):
Note: (a) In Musescore 3.6.2, the Mixer does not response to selection on the score screen area, a control in the Mixer must be selected with a mouse click first, before any adjustment is made. (b) It is not possible to add or remove channel inside a instrument on a score inside Musescore. To add or remove a channel, or set default values, a custom instrument must be created utilizing a instruments.xml. The topic is covered in the developers' handbook. (c) Parent control strip is formerly referred to as "part track".
The Master Gain controls the overall output volume. To adjust it, click and drag the slider handle or enter a value in the box underneath.
When an instrument on a score contains more than one channel. A parent control strip is shown in the Mixer, it has an arrow button on the top left corner. Click the arrow to show or hide all channels. Parent control shadows the first child control, modifying values on parent control modifies all children values.
At the top a green S Solo button and a red M Mute button: click to toggle on and off. If any Solo button is checked, unSolo channels are muted regardless of their Mute status. These modify a channel, not voices.. To mute a voice, jump to Mute Voice
The dial below the mute button controls panning left and right. You can click and drag. Note that value 64, not 50, is center pan.
The slider controls the playback volume. This is a final post process output volume. The data size 127 is an arbitrary number not related to MIDI velocity, default 100 value is 90% sound sample volume, more info.
Not to be confused with Long instrument name and Short instrument name in Staff / Part properties.
Display Instrument name or Channel name. Does not affect score visually.
The details area displays and provides finer control of the currently selected channel.
Playback option to be used with Musescore Parts feature.
Not to be confused with Long instrument name and Short instrument name in Staff / Part properties.
Text for display within Mixer only, also known as Part name in Staff / Part properties. Does not affect score visually. Does not affect sound.
Channel name cannot be modified inside Musescore, use custom instruments.xml instead, more info
Affects the whole instrument:
Changing without understanding will mess up your score audio.
Understand difference of channel and voice first, you may not want to edit this field. Consider these alternatives first:
If none of the above options fit, read on to edit sound.
The sound option is the sound data that an instrument channel use for playback. The data reference method depends on the order of soundfonts in the Synthesizer, pay attention to Synthesizer setting before you close and restart Musescore.
Correct audio won't be produced unless you setup Drumset correctly, you must understand the sound's layout.
The drop-down menu lists every sound from SoundFont loaded in the Synthesizer. They are ordered as the order of soundfont files in the Synthesizer: SF2/SF3 by MIDI Bank first, then SFZs. It is not an alphabetical order. To jump to the sound you desire quickly, while the list is open press on your keyboard (once or more) the first letter of the name.
Sound is formerly named Patch.
Same as volume slider on control strip
Same as panning slider on control strip
Color for display in Mixer only, does not affect score visually. Affects whole instrument. To change, click the colored rectangle to pick from the color palette.
The output MIDI port and MIDI channel. As of Musescore 3.6.2, MIDI output driver of the program only use 1 port and 16 channels on the operation system.
The reverb and chorus value sent to MIDI out. Sent to MIDI devices only. Does not affect MuseScore's built in audio playback.
Mute individual Voice. Each row represents one staff of the instrument. So pressing '2' on the top row will mute the second voice of the first staff of the instrument. This field is different from all others as it affects voice instead of channel.
Understand the concept of channels. You can also do these instead:
Some instruments come with multiple channels that you can switch audio playback to and from. For example, the build-in string instrument (violin, viola, cello etc.) has three channels: "arco" (or "normal"), "pizzicato" and "tremolo." The build-in trumpet has two channels "open" (or "normal") and "mute".
To switch channel, add a pre-configured Staff Text or add a plain one and edit it, as explained below. All subsequent notes of affected Voice(s) will switch to play the sound assigned to that channel, unless instructed to do otherwise with another Staff Text object. For example, all notes after a 'pizz.' Staff Text use the "pizzicato" channel, to return to arco (use sound of "normal" channel), a new 'arco' text must be added.
The 5 build-in pre-configured Staff Text in the Text palette (pizz., arco, tremolo, mute, open) instruct all four Voices of a staff to use respective channel. They affect one particular staff, but not the other staffs of the same instrument.
The 4 build-in pre-configured Staff Text in the Text palette (S/A, T/B, T/L, B/B). They only work on:
They affect one particular staff, but not the other staffs of the same instrument.
To use a custom Staff Text :
