FM8 : How to turn down the final envelope release (ADSR) ?

Arnmo

How to turn down the final envelope release in FM8 ? I know sounds come from several operators where it's possible to modify parameters. But what i'm interresting in, is where (or how) could I turn down the final global release at the end of the process ?

I've tried to shut down the Amplitude Envelope Release (in Easy/Morph tab) but there still be sound running even if you release the key. Sometimes, the sound never really stop. You can try it on [PRIS]2 preset for example, if you want to see what i'm telling about.

Thank you for your help
