16 Chapter 1 Logic Control—Basics
• EXTERNAL CONTROL
is assigned to the
MASTER
fader level. Only use an expression
pedal with this socket.
The polarity of the foot switches is determined by the Logic Control when powered up.
Therefore it is useful to first connect the foot switches, then power up.
Power Up
Once everything is connected, press the power switch found to the rear left of your
Logic Control and Logic Control XT units. Once powered, the displays will illuminate
and the LCD will display a welcome message. Of note is the firmware version number
found in the bottom right hand corner of the display. Each fader will slide to the top,
and back to the bottom, of its travel. This self-diagnostic power-on procedure indicates
that your Logic Control units are functioning correctly.
Your computer and MIDI interface can be powered up before or after the Logic Control
units. Logic can be launched either before or after the units have completed
initialization.
About Software and Firmware
The Logic Control and Logic Control XT units have no “intelligence” of their own. Their
functionality is host software-based, making them completely reliant on Logic to tell
them what to do/how to behave. What this means is that the Logic Control cannot
perform any function that Logic itself cannot do. It also means that if Logic is not
booted, the Logic Control units will do nothing at all.
The plus side of this approach is that the units represent the ultimate in upgradable
hardware. As new functions are added to Logic, Logic Control will also be able to
access and control them.
The Logic Control units do, however, have a form of software called “firmware”. This
firmware is much like the BIOS found in your computer. New “behaviors”—at a
hardware level—such as an improved control of the fader servo motors and changes to
the display can be made via firmware updates.
The firmware is stored on an EEPROM (Electronically Erasable Programmable Read Only
Memory) chip. It can be updated via a simple MIDI dump procedure, in the form of a
MIDI file.
Should new firmware become available, you can simply download the appropriate
MIDI file and play it to your Logic Control unit(s), which will be updated accordingly.
The steps required to perform a firmware update will be outlined in the readme file
which accompanies the file. Please read this before attempting any update.
