Cable switchers in the Logic Pro Environment
Cable switcher objects route events, rather than generate them. Any kind of MIDI or meta
event can be routed by a cable switcher. The only exception is events that match the cable
switchers Input definition. These events change the switch position (the routing), rather
than pass through the cable switcher.
A cable switcher can be assigned to any fader style. It’s practical to use the text fader
style, as it allows you to label the switchers various routes. Use Auto Style to actually
display the switch routing, as shown above.
A cable switcher can have up to 128 separate cable outputs—a new output is generated
each time an existing output is cabled to another object. You can click an auto style cable
switcher to step through the outlets (including the last, uncabled one).
Incoming events that match the cable switchers Input definition change the switch
position to that of the incoming data value. (If the data value is greater than the number of
switch positions, the last, uncabled outlet is selected.)
Data values of 126 and 127 have a special effect.
An event with a value of 127 increases the output number. If you’re on the switchers
last output when this event is received, you’ll jump back to the first output. This is just
like clicking the fader.
An event with a value of 126 decreases the output number. If you’re on the switchers
first output when this event is received, you’ll jump to the last output.
Meta event faders in the Logic Pro Environment
Meta faders generate special meta events, which are used to control certain Logic Pro
functions, but have no MIDI meaning, and are never sent to the MIDI output.
In some cases—Go to Screenset, Go to Project, and so on—you don’t need to cable meta
faders into another object for them to work. You can use cabling to process meta events in
the Environment, and alter their effect.
However in the majority of cases—Set fader range minimum, Bang!, Set transformer
operation minimum, and so on—the meta fader must be cabled to the object being
affected.
