Cable Switchers
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 switcher’s Input definition. These events will change the switch position (the routing),
rather than pass through the cable switcher.
A cable switcher can be assigned to any fader style. It is practical to use the text fader
style, as it allows you to label the switcher’s various routes. Use the auto style to actually
display the switch routing, as shown here.
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 switcher’s 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.)
