To display the Synthesizer: from the menu, select View→Synthesizer.
The Synthesizer controls MuseScore's sound output and allows you to:
The Synthesizer window is divided into four sections/tabs:
Set as Default: When you open MuseScore, the Synthesizer always assumes the current default settings. If you want a new default to apply at the next session, change the settings as desired, then press the Set as Default button.
Save to Score / Load to Score: You can save a particular configuration of settings to an individual score by pressing the Save to Score button. When you next load the score, use the Load from Score button to transfer the stored settings to the Synthesizer.
Note: Only one set of Synthesizer settings can be in effect at a time—i.e. if multiple scores are open at once, it is not possible to make changes to the Synthesizer in one score and leave other scores' settings untouched.
Click on the Fluid tab to access the control panel for SF2/SF3 SoundFont sample libraries. By default, the SoundFont
FluidR3Mono_GM.sf3 should already be loaded.
You can load, rearrange and delete soundfonts as required. Playback can be shared between any combination of different soundfonts (and/or SFZ files). The order of soundfonts in Fluid is reflected in the default order of instruments in the mixer.
To be able to load the soundfont, it first needs to be installed in your Soundfonts folder. This will ensure that it appears in the list in step 2 (above).
If you have not changed any sounds in the Mixer, then the SoundFont at the top of the list is the one that will be used for playback. However, if you are using the Mixer to play different instruments with sounds from different SoundFonts, playback will only work correctly if you have the same SoundFonts loaded in the same order in the Synthesizer. Therefore, if you are using multiple SoundFonts, it is advised to click the Save to Score button in the Synthesizer, so that the next time you open that score you can recall the list of SoundFonts loaded (and other Synthesizer settings) with the Load from Score button.
This removes the soundfont from the synthesizer but does not uninstall it from the Soundfonts folder: it will still be available if you wish to reload it later.
Click on the Zerberus tab to access the control panel for SFZ sound sample libraries. You can add or delete files in a similar way to the Fluid tab. Note that, as with Fluid, the the SFZ files must first be installed in your soundfonts folder before they can be loaded into the synthesizer.
At the right in the Synthesizer are two sliders. One controls the playback volume, the other controls the volume of the optional built-in metronome. You can turn the metronome on or off by clicking the button underneath its volume slider. As with all the rest of the Synthesizer controls, any changes made here are temporary unless saved to the score or set as the new default.
The Master Effects tab of the Synthesizer houses the Zita 1 stereo reverb and, as of version 2.0.3, the SC4 stereo compressor modules. Two slots are provided, "Effect A" and "Effect B," both with a drop-down list of available effects – including the option to set one or both channels to "No Effect." The effects are applied in series: Effect A → Effect B.
To store an effects configuration as the default option for the synthesizer, click the Set as Default button. If you subsequently change the effects set-up, you can restore whatever settings you made the defaults by clicking the Load Default button.
You can store a particular effects configuration with a score by clicking on the Save to Score button, and later load those settings from the score by clicking on Load from Score.
The Zita 1 stereo reverb module allows you to simulate the ambience of anything from a small room to a large hall. The pre-delay, reverb time and tone of the reverb can be finely tuned using the controls provided:
Note: EQ1 and EQ2 affect the tone of the reverb only, not the dry (unprocessed) signal.
To quickly set up an effects patch, set "Output" to "Mix" and adjust the "Mid RT60" control to the desired reverb time. Then fine tune the effect as explained above.
The SC4 stereo compressor (available as of version 2.0.3) gives you fine control over the playback's dynamic range, reducing the volume variation between loud and soft sounds. It offers the following controls:
To quickly set-up, try setting RMS = 1, Threshold = -20 db, Ratio = 6. Increase Gain to restore the lost volume. Then fine-tune as explained above.
For Concert Pitch instruments, MuseScore uses the A4 = 440 Hz pitch standard by default. To change it, simply enter a new value in the
Tuning tab of the Synthesizer.
Like all other Synthesizer settings, the master tuning affects playback within MuseScore but does not affect exported audio files (WAV, OGG, MP3) unless the Save to Score option is selected.
Notes: Applies to all scores. Current session only (tuning resets to default on MuseScore exit). Affects playback but doesn't affect exported audio files (WAV, OGG, MP3, and MIDI).
Note: Applies to all scores. Current session and all subsequent sessions (until you change it again). Affects playback but doesn't affect exported audio files (WAV, OGG, MP3, and MIDI).
Note: Applies to current score for current session, use the Save to Score button, and settings can be recovered in subsequent sessions with Load from Score. Affects playback and exported audio files (WAV, OGG, MP3).
