2 - Principles of operation—Using the PODs2–3more time will bring I/O SETUP to the frontonce more.2.3.2 Navigation in screensIn the screens above, there are no POD-selectableparameters. In these cases, it is necessary to useanother method of working.This is provided by the cursor keys and the ENTERkey beside the JOG/SHUTTLE dial.Use the cursor keys to move the cursor (å) from fieldto field, and the ENTER key to select a value fromone of a number of options.2.3.3 Using the JOG dialSometimes there are numerical values to be set.These can be entered using the JOG dial (when theJOG/SHUTTLE indicator is off and the Dial Editoption is checked—see 3.3.7, “Dial edit”).The JOG dial can also be used to change the valuesof a highlighted item which can also be edited by aPOD (in the screen above, there are no such values,but the MODULE screen in 2.3, “Using the PODs”contains many such values). Note that the JOG dialcan be used to control the values of a parameter thatis not in the currently active POD row.In some screens, the JOG dial may be used instead ofthe cursor keys to move the cursor around the screen.The instances where this can be performed are usu-ally obvious and therefore will not be described indetail.In certain special screens, the outer SHUTTLE wheelis used to change the function of a screen (forinstance in library screens, it changes the function ofthe JOG dial from a device selector to a characterselector.The numeric keypad may also be used for the directentry of numeric values in certain cases.2.3.4 One channel or one parameter?The TM-D4000 provides two options for the settingof module-based (as opposed to system-based)parameters.If one module (or stereo linked pair of modules) is tohave many parameters changed, at one time, thechannel is selected (see 2.3.5, “Selecting channels”below) and the MODULE screen is used, as shownbelow:In fact, the MODULE “screen” is two screens(EQ/AUX/PAN and EQ/DYN (dynamicsprocessor)). Pressing the MODULE key will changebetween these two screens (see 2.3.1, “Selectingscreens” for more information on multiple screens).Sometimes, though, it makes more sense to view andadjust a single parameter on many modules simulta-neously. For instance, here is the screen to adjust thelevels for Aux send 1, accessed by pressing theAUX 1 key:Note that again, this “screen” is actually two screens,the first for the channels 1 through 16, and the secondfor channels 17 through 32. Repeated presses of theAUX 1 key will cycle between these two screens.
