 The opposite of this node is the 'Demux9', which demultiplexes or routes
 the one input signal to one of the 9 outputs.
+
+Tip:
+    An interesting use case for this node is to use it as (up to) 9 step
+    control signal sequencer. Leave the 'in_1' to 'in_9' ports unconnected
+    and dial in the desired value via the parameter knobs. This can lead to
+    interesting results. Even more interesting it can become if you stack
+    multiple 'Demux9' in series and connect just some of the input ports
+    for slightly changing sequences. Attach a slew limiter node (eg. 'LSlew'
+    or 'ESlew') if less harsh transitions between the input routings is
+    desired.
