If you're using "
FluidSynth" with QSynth, you should tell
Qtractor about the SoundFont that you're using. When you do this, you enable
Qtractor to help you choose instruments ("patches").
Click on 'View > Instruments'
In the "Instruments" window, click "Import."
Navigate to /usr/share/soundfonts
Select the SoundFonts that you would like to use. The default is the FluidR3 GM SoundFont, but you can choose multiple SoundFonts to use simultaneously.
Close the "Instruments" window to return to the main Qtractor window.
