54 Chapter 7 Control Surface Support

Logic Pro 7.2 provides updated control surface plug-ins for several devices: the factory

key command assignments already support the Key Repeat function (if useful and/or

applicable to the device)—making changes unnecessary for use of this new

functionality.

If you want to enable the Key Repeat function for your own assignments, you may

need to use the re-learn option for the assigned message. Key Repeat messages must

include the Lo7 byte, which provides information on the up (released) or down

(pressed) state of the assigned button.

Logic 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 1–127 is used for the button pressed message. The zero (0)

value is generally used for button released.

Note: Some control surfaces may use different value ranges (CM Labs MotorMix, for

example). Assigning the used value range to the desired Min and Max values ensures

that key repeat also works with such devices. This, however, also 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 on and button release

(off) states, the complete assignment will not work). Please consult your control surface

manual for further information about the values used.

Intermediate Stop at Default Value

Pressing the Option button on your control surface, while editing a parameter assigned

to a rotary encoder, enters “Relative Controller mode”. In this mode, a turn to the right

sets the encoder to its maximum value. A turn to the left sets the encoder to its

minimum value. Logic Pro 7.2 enhances this mode: it now also stops at the encoder’s

default value.

As an example: When the Pan knob is somewhere left of center, turning the encoder to

the right—with Option pressed—will initially set the pan parameter to its center

(default value) position, with a further right-turn setting the full right (maximum value)

position.
