The screen for preview/button src is different on midi, that’s why it can’t be done, I should image you will loose options on midi if that was the case. Glad it’s sorted now
The preview uses the settings of the selected Audio track to preview the sample. Be aware of this: If the settings are such that they are severely altering the sound (extreme filtering, super short amp. envelope, etc…) then your preview will be subjected to that.
If what you’re doing is choosing a replacement sample, this is just what you want. If you are picking a sample for a track in a blank pattern, the settings are neutral, and also what you want. Sure, there is some scenario where you really intend to “start afresh” as you are picking the sample - and the only way to do that is to clear out the parameter pages first.
