I tried this in sylenth I can get the life that the transient has, Is this maybe FM or something?

you need pulse 1 voice
LP filter.
to get the transient you need 2 Filter envs in sylenth one slower and one faster.
or if you have ANA use the curved decay.
I got it! thanks, it was all about that curve decay
