I have found that from time to time, the release times of Augmented Voices and Strings patches go AWOL - even factory ones.
The only way to fix it is to do a reinstall of the affected products. I do this via ASC.
I always have the latest ASC and Augmented synths (in fact I keep all Arturia synths updated). My PC is Windows 10 22H2 with extended security patches enabled.
The only thing I can think of that triggered the issue is that I installed a new Aurura product (Ocean Reverb). That is only circumstantial, however.
Note: Note all Augmented series synths have “Natural/Synthetic” setting to the right of the release parameter. Augmented Voices and Strings does not.
Reinstalling these synths is getting a bit old.
Any one else having this issue.
Note: I have dropped a note to Arturia support.
