If you can clarify whether you’re looking for a PolySynth Preset, or a Program that uses PolySynth, that would improve your search.
As Brock mentioned, the Factory Programs/Presets cannot be edited or erased.
Using H90 Control is the best way to find a certain Program/Preset:
- If searching for a Program, use the Program library and select the PolySynth filter: https://cdn.eventideaudio.com/manuals/h90/1.11.4/content/h90-control/program-library.html
- If searching for a Preset, use the Preset library and select the PolySynth filter: https://cdn.eventideaudio.com/manuals/h90/1.11.4/content/h90-control/edit.html#preset-library
Sounds like you may be searching for the “Dramatic Swell” Program.
