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 switcher's 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 switcher's first output when this event is received, you'll jump to the last output. Meta Event Faders Meta faders generate special meta events, which are used to control certain Logic Express functions, but have no MIDI meaning, and are never sent to the MIDI output. In some cases (such as Go to Screenset, Go to Project, and so on), you do not need to cable meta faders into another object for them to work. Even in these cases, 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. Here's a quick summary of the currently implemented meta events that can be generated by faders: Meta event 46 49 50 51 52 96 97 98 99 100 122 123 124 Controlled Logic Express function Assign Alias Go to Screenset Go to Project Go to Marker Stop Playback Set fader range minimum Set fader range maximum Set the fader value without sending Bang! Causes the fader to resend its current value. The bang data value can be used to make the fader increment-without-rollover (127), decrement-without-rollover (125), increment-with-rollover (123) or decrement-with-rollover (121). Use values one less than those shown to have the bang passed through to all connected faders. Tempo Control (See Using the Tempo Fader.)
