The Presets Section lets you capture different states of the RTGS3 controls, save them to a file, and morph between them.
[Preset Digits] = a dimmed Preset Digit indicates that that slot is currently empty.
Clicking on a dimmed Preset Digit captures the current settings of all the RTGS3 controls into that slot. (Settings made in the Controllers Pane are not captured in these presets: see Controllers Presets for more info.)
Clicking an activated Preset Digit recalls the settings stored in that slot.
Option-Clicking an activated Preset Digit erases the settings stored in that slot.
Morph Slider = use this slider to interpolate between different presets. For example, setting this slider so that it displays "1.5" will move all the RTGS3 controls to a point exactly half-way between presets 1 and 2. You may also change this setting by clicking on the number displayed, typing a value and pressing the enter key.
Clicking the Gear icon opens up the Presets Setup window:
Main Presets File Operations = use these buttons to save and open RTGS3 presets files to and from your hard disk.
"ERASE ALL PRESETS" button = clicking this button twice clears all RTGS3 presets from memory. This does not affect RTGS3 preset files that have been saved to disk.
"Morph Presets Slider Controller" checkbox = activating this checkbox enables remote control of the Morph slider using one of the RTGS3 controllers. See Tutorial 2: Controllers Explained for more info.
