Send trigger when volume decrease

Hi every body.

I need to trigger something when the sound decrease. It seems so simple, but i try to explain.

I hit a cymbal that go thru an FX. This FX is very loud and sunddenly it decrease very speed.
I need to trigger something when the sound decrease. But the volume is never the same. I can't work with a db value threashold because the db Value depend of the power of the hit on the cymbal. But the FX is always Loud ans suddenly low.
I try with an envelope follower and array average but it didn't do the job beacause it need a db threshold value.

I think i need something to calculate the difference between loud sound and low sound. When the difference is more than X db, so send trigger.
i try with array without success.
Somethink to store the max db value and when the next value is X db under, it send a trigger...

Thank you to help.

Interesting problem.
I will have a look at it later.
But maybe you have something to do with the module "array standard deviation".

Maybe it's a solution.
You had to adjust the release time of the two envelop followers according to your sounds, and then the threshold.

All the best
