+    Roland Sound Canvas SC-55mkII
+
+    Skeleton by R. Belmont
+
+    The Roland SC-55mkII is an expander (synthesizer without the keyboard)
+    from 1994.  It has 28 voice polyphony, is 16 part multitimbral, and
+    outputs 18-bit stereo samples at 32 kHz.  The synthesis engine uses a
+    combination of Roland's LA and straight PCM playback.
+
+    The front panel includes the power switch, a headphone jack with volume knob,
+    a second MIDI IN port, a large LCD, ALL and MUTE buttons, and a group of up/down
+    buttons for Part, Level, Reverb, Key Shift, Instrument, Pan, Chorus, and MIDI Channel.
+
+    Main PCB:
