120 Chapter 5 EuCon Support of Euphonix MC and System 5-MC
Faders
The following section outlines the functionality of the MC fader elements in Logic Pro.
You should note that this section is limited to descriptions of Logic Pro specific
features. Please refer to the device operating manuals for information on basic fader
functionality.
Solo Keys
This key activates the Solo button for each channel strip.
On Keys
The MC On keys provide the same functionality as the Mute buttons in Logic Pro, but
behave in a way that may not be as expected:
 An MC On key must be active (lit) to hear the channel.
 If a channel strip is muted in Logic Pro, the corresponding MC channel On key is not
lit.
L LED
When the Logic Pro channel strip being controlled by the fader belongs to an
automation group, the L LED of the channel strip is illuminated.
Touching Fader Selects Track Preference
Please note that the “Touching fader selects track” preference of Logic Pro (Logic Pro >
Preferences > Control Surfaces > Preferences) does not apply to the MC and System 5-
MC—when they are used with the EuCon protocol. This function is offered by the MC
itself, with the “Select channel by touching fader/joystick” preference.
Choosing Automation Modes
The MC and System 5-MC only support Read and Write automation modes. Logic Pro,
however, also features Touch and Latch automation modes. When you use these
devices with Logic Pro, activating the Read/Write mode in the Touchscreen activates
Touch mode in Logic Pro. Latch mode can not be activated with the MC or System 5-
MC.
To choose an automation mode on the MC:
1 Press the Wave and Select keys simultaneously.
2 Select the desired automation mode in the pop-up menu displayed on the
Touchscreen. You can choose between:
 Isolate: Automation mode is off.
 Read: Activates Read mode in Logic Pro.
 Write: Activates Write mode in Logic Pro.
 Read/Write: Activates Touch mode in Logic Pro.
