+                       The argument must be a number between 0 and 100. The default value
+                       0 corresponds to linear scaling. That is, the value of the mixer
+                       channel is increased or decreased in fixed time intervals until the
+                       destination value is reached. Exponents between 1 and 99 cause low
+                       channel values to be increased more quickly than high channel values.
+                       Large exponents cause greater differences. The special value 100 sets
+                       the destination value immediately. The command then sleeps for the
+                       configured fade time.
