Title pretty much says it all. It would be so great if a enabling or disabling a patch that passes live audio
did not create a popping sound. We need a resource efficient microfade on audio when the patch is activated / deactivated!
I cannot find any other way.

keep cool!!!!!!!!!

actually Usine makes a small fade-in/fade-out when the patch is activated/deactivated on the grid.
the fade in is generally 128 samples which is a good compromise:
for example if you trigg a drums loop, the attack must be preserved so we can't use a long fade-in.
but unfortunately, on some kind of sound, like low frequencies basses, you can hear a pop because the fade is shorer than the wavelength.
So, on your patch, when you need a longer fade, use a volume module with a data/smooth module to provide the fade you want, depending of the nature of your sound.

. maybe try as a workaround to anticipate and activate the pach a bit before it's needed with an appropriate fade. for example if quantisized put activation on the last step (15 on 16), with a fade of one step to trigger a loop on next bar, or a manual little pach that enable the pach while fading the voulume out should do the job and be modular...

Of course there's always a way with Usine...! Sorry to get all dramatic.
I tried a lot of crazy ideas that didnn't work and it seemed like from other forum topics there was no solution for this problem.
Now thanks to the smooth module I have made an example that works fine for audio passing through the patch, however I may need to change my approach if there is an fx tail or audio being generated from within the patch independant of the input..
Here's what I have so far.. maybe there's a lighter way?
