+# What
+
+juicysfplugin is an Audio Plugin for playing MIDI music through a soundfont synthesizer.
+
+[JUCE](https://github.com/WeAreROLI/JUCE) is the framework for making audio plugins.  
+[fluidsynth](http://www.fluidsynth.org/) is the soundfont synthesizer.
+
+juicysfplugin works as a standalone application (for playing around). You can plugin your hardware MIDI keyboard, or play with the software MIDI keyboard. Or router MIDI messages into it from a virtual MIDI controller (e.g. the macOS IAC Bus).  
+
+juicysfplugin is also an Audio Plugin. VST, VST3, AU, AUv3.
