Hey, I might be wrong about this - If so please correct.
I just updated the CS-80V to 2.5 - and whilst I was not too surprised to see the 'not found' dialog pop up in Logic, I WAS surprised to see that any user-presets that you have saved (because obviously those who don't always bounce to disk - should at least save tweaked sounds as a preset

- in case an update re-initializes the plug

) - The 2.5 update overwrites any additional presets that you have saved.
Had to go back to the previous installer, and then Export my preset Bank.
Not sure WHERE arturia save presets, but any non-at-install presets are vanished after the update.
Just thought I would warn people, as that reloading old project "oh, i can't get that sound again" thing is somewhat annoying.
