Logic Express guides you through the re-learning process. The current MIDI message is
automatically cleared, Learn mode is activated, and a help tag prompts you to send the
desired MIDI message.
Releasing the assigned button—after learning the MIDI message—automatically creates
the Lo7 byte, and assigns the Lo7 value (for the button release message) to the Min
parameter. The Lo7 value for the button pressed message is automatically assigned to
the Max parameter.
Typically, the value range of 1 to 127 is used for the button pressed message. The zero
(0) value is generally used for the button release message.
Note: Some control surfaces may use different value ranges (CM Labs Motormix, for
example). Assigning appropriate Min and Max values ensures that the Key Repeat function
will work with such devices. This, however, means that you need to take care when
manually changing the Min or Max value for a key command; in cases where the Min and
Max values do not match the button pressed (on) and button released (off) states, the
complete assignment will not work. Consult your control surface manual for further
information about the values it uses.
Assigning Buttons to Key Commands
In addition to assigning controllers to parameters, you can assign control surface
buttons—and button or key release messages—to key commands.
