+    Yamaha MU-15 : 16-part, 32-note polyphonic/multitimbral General MIDI/GS/XG
+                   tone module
+    Driver by R. Belmont and O. Galibert
+
+    Essentially a screen-less MU10 (SWP00, identical wave rom) with a gate-array based
+    hack to connect the wave rom space to the adcs so that effects can be applied to
+    analog inputs.  Entirely controlled through midi.
