Parallel Swells is not a factory preset.

If you are trying to import a preset file, see #12 here: https://cdn.eventideaudio.com/manuals/h90/1.12.5/content/h90-control/edit.html#parameters-edit-menu

Otherwise, you can manually copy the parameters in the image he shared in the thread above. It’s basically setting everything to 0, set the Chop parameter to one of the Swell options, and adjust the Rise time your liking.
