 * Midi synthesizer
 
   - for macOS we recommend [SimpleSynth](http://notahat.com/simplesynth/)
+  - for Linux, [FluidSynth](http://www.fluidsynth.org/). Documentation abouut how to install it can be found [here](https://wiki.archlinux.org/index.php/FluidSynth). Once installed and configured, the output of `aplaymidi -l` should look alike:
+
+  ```
+   Port    Client name                      Port name
+   128:0    FLUID Synth (32076)              Synth input port (32076:0)
