   + Tap Tempo
 
-    (Stay tuned...)
+    I was not able to find the magic incantation to set tap tempo over
+    USB (if, indeed, it's even possible). However, this function can
+    be assigned to one of the Fender foot pedals if you need it at
+    your feet.  Haven't totally given up on this and have an idea for
+    "faking" it over MIDI.  Now I just need the time to code it...
