I don’t think I was aware of GPUserPresets,

Examples are here:

• Duplicated rackspace that differs only in the preset loaded into a plugin - #18 by dhj
• VST3 Presets - #15 by pianopaul
• https://community.gigperformer.com/t/rackpanel-alias/7217/13?u=npudar
• Can I script a rotary knob to change plugin preset? - #34 by rank13
