MuseScore supports the SoundFont format (.sf2, .sf3), which is a single file containing one or more virtual instruments. MuseScore comes packaged with, MS Basic, a essential set of instrument sounds for common score creation. Visit Handbook (for MuseScore 3)'s SoundFonts and SFZ files Chapter for a list of downloadable sf2, sf3.
For a more realistic, high quality virtual instrument experience,
Once you’ve downloaded a SoundFont to your computer, there are two ways to install a SoundFont in MuseScore 4:
[Content on its way]
By default, MuseScore looks for SoundFonts in the following directories:
[Content on its way]
You can also specify in which folder(s) on your computer MuseScore looks to find SoundFonts. If a SoundFont is installed in a recognized folder (“directory”), it will automatically be available in MuseScore.
First, specify the SoundFont directory in MuseScore 4:
Once a SoundFont is installed, all you’ll need to do is choose the SoundFont you want for each instrument in your score. To do this:
Repeat this process for each instrument. In most cases, MuseScore will automatically map instruments to their correct sounds in the specified SoundFont, as long as that SoundFont is using the correct MIDI instrument definitions.
To uninstall a SoundFont, simply open the folder where its file is installed and delete it.
When you select a SoundFont for a given instrument, MuseScore uses the General MIDI standard to automatically select the corresponding sound from within the SoundFont. However, this may not always be sufficient. The SoundFont in question might not be GM-compatible, or there might be multiple variants of a sound you wish to choose between, like fingered versus picked for electric bass.
When you select a SoundFont with only a single sound or only a single drum kit, MuseScore will use that. But for SoundFonts that represent collections of sounds, manual selection of individual sounds within a given SoundFont is currently not supported (as of Musescore 4.0). Therefore, if you need to select a sound for an instrument other than the one specified by General MIDI, you will need to employ a workaround for now. The ability to select individual sounds within SoundFonts is planned for MuseScore 4.1, but meanwhile, the following methods provide similar functionality:
You cannot edit .sf2, .sf3 and sfz files inside Musescore. Use a 3rd party software such as Polyphone, see Soundfont, MIDI velocity and instruments.xml.
Users of MuseScore 3.6 and earlier may be accustomed to using the Zerberus player, which supports the .sfz file format. In building a new system that now supports VST instruments, changes were required that necessitated the removal of the Zerberus player, as well as the Synthesizer found in previous versions of MuseScore. Consequently, some functionality has been lost in this process, including the ability to map specific instrument sounds like pizzicato and tremolo to specific MIDI channels. Our highest priority in future releases of MuseScore 4 is to again support this functionality for VST, SoundFont and the Muse Sounds libraries. Users who rely extensively on mapping .sfz sounds to specific performance directions are advised to continue using earlier versions of MuseScore until we re-enable this capability in MuseScore 4. It is worth mentioning that the new systems we are planning will be much more flexible, easy to use and powerful than those found in MuseScore 3.
For those who wish to still use SFZ sounds in MuseScore 4, good alternatives would be the open source VST samplers, Sfizz (Windows, Mac & Linux) or Sforzando (Windows & Mac), both of which support SFZ playback.
