When any is activated, the green LED to the right of the GLOBAL VIEW button will illuminate. Pressing multiple GLOBAL VIEW buttons simultaneously will display the objects of the selected types. To do so: Hold down any GLOBAL VIEW button, and add or remove other object types by repeatedly pressing the other desired GLOBAL VIEW buttons. The display order of the objects matches the order of these buttons on the front panel of the Logic Control. As an example: to see the busses and the outputs, hold down BUSSES, and then press OUTPUTS. Further information on Global View is found in the Global View section on page 18. Function Button Zone There are three areas in this zone--Modifiers, Automation and Utilities. Modifier Buttons The four buttons in this area are similar to those found on your Mac OS or Windows computer keyboard (however independent from them). Many of Logic's functions behave differently when one or more "modifier" key(s) is pressed, in conjunction with another key or mouse click. All "modified" Logic Control commands are covered in each function's description. A generic, and brief, description of each button follows: · SHIFT--an alternate function/meaning for a button · OPTION--the function applies to all objects. For relative value changes: the value is set to the minimum or maximum, depending on whether you increase/decrease it. 52 Chapter 2 Logic Control--Details · CONTROL--while held down, the Group Clutch is engaged, i. e. · C/ALT--fine tuning variation of the function. Automation Buttons The five buttons in this area activate/deactivate the various automation modes of Logic. Simply choose the channel you wish to automate, select the Automation mode via one of these six buttons, and move the corresponding fader. The modes are outlined below: · READ/OFF--Pressing this button repeatedly toggles between the "Read" and "Off" automation modes. · Off--Automation is off. The fader will neither send nor receive automation data. · · · · Existing automation data remains untouched. It will still behave as a fader, however, and will adjust the volume or pan position etc. · Read--The fader will read (follow) any existing automation data, but will not write data, regardless of any movements you make with the mouse or external control device. TOUCH--Writes new parameter changes when the fader is "touched" or V-POT turned during playback. Any existing track automation data (of the current fader type) will be replaced by new movements as long as the control is active--i. LATCH--Similar to Touch mode, but the control remains activated, even when the fader is no longer being "touched" or V-POT being turned. In other words, following the release of the fader, the current fader value will replace the existing automation data for as long as the sequencer is in playback mode. WRITE--Overwrites all existing automation data, or creates new automation data. Please consult the readme files of updated versions. Chapter 2 Logic Control--Details 53 When the OPTION key is held down, pressing one of the Automation buttons chooses the selected automation mode for all tracks. When an automation mode has been selected for all tracks, the button's LED will illuminate whenever the OPTION key is held. N. [. . . ] This way, an LED has the same ID as its corresponding switch. LEDs Received: 90, ii, ss Set LED status Transmitted: None ii LED ID (See Logic Control--Control Surface Layout and IDs section on page 181) ss LED State (7F = on, 00 = off, 01 = flashing) Example: 90, 08, 7F = Turn LED 08 on 90, 08, 00 = Turn LED 08 off Note: Switches and LEDs use the same control message. In this way, an LED always shares the same ID as its corresponding switch. 172 Appendix B Logic Control--MIDI Implementation V-POTs Received: None Transmitted: B0, 1i, XX V-POTs turned by user i V-POT ID (00­07) XX delta value in the form of ( 0 s v v v v v v ) s direction bit: 0 = clockwise, 1 = counter clockwise vv number of ticks Examples: · B0, 10, 01 = V-POT Ch. 8 is being turned counter-clockwise by 7 ticks. V-POT LED ring Received: B0, 3i, XX Set LED ring display Transmitted: None i V-POT number (0 thru 7) V-POT display control byte in the form of XX ( 0 p x x v v v v ): p V-POT display center LED state (1 = on, 0 = off ) xx V-POT mode (00 thru 03; see diagrams below) vv V-POT display position value 00 = all LEDs in ring off; 01 thru 0B see diagrams below Example: · B0, 31, 06 = V-POT 2 display shows LEDs at position 6 Note: In any V-POT display mode, a received LED position value of 00 will turn off all of the V-POT LEDs. Appendix B Logic Control--MIDI Implementation 173 V-POT Display modes available: 174 Appendix B Logic Control--MIDI Implementation External Controller Received: None Transmitted: B0, 2E, vv External Controller changed vv External Controller position value (00­7F) Example: · B0, 2E, 07 = External Controller value = 07 Jog Wheel Received: None Transmitted: B0, 3C, XX Jog wheel turned by user XX delta value in the form of ( 0 s v v v v v v ) s direction bit: 0 = clockwise, 1 = counter clockwise vv number of ticks Examples: · B0, 3C, 01 = Jog forward · B0, 3C, 41 = Jog reverse Appendix B Logic Control--MIDI Implementation 175 LCD Received: <Hdr>, 12, oo, yy, . . . , F7 Update LCD Transmitted: None oo Display offset to write from: 00 thru 37 for upper line, 38 thru 6F for lower line. yy Data: ASCII equivalents for display characters written from left to right, including line wrapping between upper and lower line.
