+// Although FE-8 supports the above registers, it has no I/O interfaces for

+// is fixed to 0x40. The second byte is between 0x00 to 0x1f and represent each

+// knob: 0x14-0x1b
+// sensing: 0x0b
+//
+// The rest two bytes represent state of the controls; e.g. current value for
+// fader and knob, bitmasks for button and sensing.
