The MIDI Control Setup window
In the case of switches which only have two positions (up or down) you can still
use minimum and maximum values in the MIDI learn popup window, but in
these cases the behaviour is a little different.
It's about what values the controller sends and whether those are high or low
enough to trigger the state change in a switch - which is always 0.5 or in the
case of the three stage switch, 33.3/33.3/33.3 (or near enough). You can set
the minimum and maximum values of the hardware MIDI control but whether
it affects the software parameter depends on whether it crosses the threshold
required to make the change.
Let's take an example. We want to control a 2-position switch with a hardware
fader. The fader value goes from 0.0 to 1.0 and the switch state will always
change when 0.5 is crossed.
The min value in the MIDI learn window corresponds with the value that will be
sent (from the controller to the engine) when the fader is at its min position
(same goes for the max value).
To explain this, you can try these 5 use cases:
 Set min value to 0.0 and max value to 0.49 => the switch cannot be
switched on because the 0.5 value can never be crossed
 Set min value to 0.51 and max value to 1.0 => the switch cannot be
switched off because the 0.5 value can never be crossed
 Set min value to 0.0 and max value to 1.0 => the switch state changes
when the fader crosses its central position
 Set min value to 0.49 and max value to 1.0 => the switch state changes
when the fader is very low
 Set min value to 0.0 and max value to 0.51 => the switch state changes
when the fader is very high
The same goes for the three-stage switches, where instead of 0.5 being the
state change value, it is divided into three thirds.
