As you've
probably realized, Spectron isn't just a plugin, but instead a system of effects. Sometimes
you'll want to load an entire preset (update the whole system), but other times
you might just want to use parts of a preset - e.g. just change the Delay module
settings. Selective loading of modules gives you this option.
1) When you select a preset from the list, the settings of any modules which are checked (see the screenshot below, where all modules are checked except Morph) are being taken from the preset you selected.
2) You can change which modules a preset loads by selecting the preset, then clicking on the checkboxes. So if you want the "Delay - Triggered Feedback" preset in the screenshot above to also load its Morph settings, just click on the Morph checkbox. Each preset remembers which of its checkboxes are checked. As soon as you click on a checkbox, this change will be saved to the preset.
3) There is a shortcut to quickly check just one module. Hold the Alt key and click on a checkbox, and it will be selected while all others are deselected.
