After some tests, I manually deleted the samples contained in the ‘user sample’ folder. Be aware that if, like me, you have saved Padshop Pro AU presets, those presets won’t be able to open with the samples used in the preset, since Padshop searches the samples used in the AU presets in that ‘user sample’ folder. You’ll have to re-import them again to make your AU presets work. Not cool…
We definitely need a better way of saving presets.
