+-- Trackpad input by Paul Hedderly
+-- Expects two inputs - one master and one slave
+-- The first is to track a contolled input for example a
+-- sound desk fader.
+-- The slave is for a fader on a non-motorised surface...
+-- The idea is that the slave is not forwarded to the
+-- first/main output until it is close in value to the master
+-- This is to avoid sudden jumps when using a secondary
+-- non-motorised controller.
+--
+-- Example config - here using a nanok as a slave to an X32
