3.3. MIDI Learn assignment
The MIDI plug icon at the far-right side of the toolbar places the instrument in MIDI learn
mode. MIDI-assignable parameters will be shown in purple, which means you can map
physical controls to those destinations inside the instrument. A typical example might be
to map a real expression pedal to the Output Trim control, or knobs and faders on your
controller to the different virtual frequency knob switches or the virtual boost/cut faders of
the plug-in.
In the image above one of the parameter controllers is red. That means it has already been
assigned to an external MIDI control. It can be reassigned, though.

♪
: Remember that you can also assign the Preset Forward and Backward arrows to an external
control.
3.3.1. Assign / Unassign controls
If you click on a purple area, you’ll put that control into learning mode. Move a physical dial,
fader, or button and the target goes red, indicating that a link has been made between the
hardware control and the software parameter. There’s a popup window that displays which
two things are being linked and an Unassign button that will disconnect the two.
3.3.2. Min / Max value sliders
There are also minimum and maximum value sliders that you can use to restrict the
parameter change range to something other than 0%-100%. For example, you might want
the Output Volume knobs to be controllable via hardware from 30% to 90%. If you make this
setting (Min set to 0.30 and Max set to 0.90) your physical dial will be unable to alter the
volume lower than 30% or higher than 90%, no matter how far you turn it. This is very useful
to prevent you from accidentally making the sound too quiet or too loud when performing.
In the case of switches which only have two positions (On or Off – like the LOW PASS and
HIGH PASS switches), those would normally be assigned to buttons on your controller. But
it is possible to toggle those with a fader or other control if you like.
