Could be fine to have a fade out time from 0 sec to 9 sec , like the Pigtronix Infinty
And to push even further A different time on each Part!
Separate fade in fade out options would be optimal. Log, -log, and linear options would also be ideal. I know that may not happen soon, or ever but … it would be ideal.
Thank you for the request and feedback! We will look into this in some time, but will be addressing more pressing features for now.
