+ 
+    The Roland SC55 is an expander (synthesizer without the keyboard)
+    from 1991.  It has 24 voice polyphony, is 16 part multitimbral, and
+    outputs 16-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.
+ 
+    The SCC-1 is an ISA board variant of the SC55 with a MPU-401 frontend added to
+	communicate with the synth.
