+# Status
+
+Currently, the following elements of the Mustang Floor MIDI spec are
+implemented:
+
+  + Patch change
+  + EFX bypass (on/off)
+  + Amp CC messages (except for on/off)
+
+I'm using WinPCAP and tshark to snoop communication and plan to
+implement all features accessible from the Fender FUSE application.
+However, some targets listed in the MIDI spec (e.g. amplifier on/off,
+tuner mode) are not controllable from FUSE and it may take some time
+and luck to figure out the protocol.
