Presets questions: Which parameters are not stored in a p10 preset ?

Hi,

I'm curious about what exactly is stored in a preset. I understand that this might vary for every firmware version, but how can I find out the specifics?

Switching gears to firmware: what has been your experience with (beta) firmware version 2.04 and its compatibility with older presets/sounds?

Additionally, is it anyway possible to replace/erase, or modify and store the factory presets?

Best regards,
Arjan
