Hi! Found something that works for me. Hope it helps! > [@AHDSR probem on volume with Loop region and release](https://qa.fmod.com/t/ahdsr-probem-on-volume-with-loop-region-and-release/13833/4): > > Hi there! I have been fighting against this same problem for hours and finally found a solution. In my case I needed the 6 tracks inside the main music event to run in sync and loop, but fade in or out depending on a discrete parameter value. Since AHDSR in clips nor tracks was working the way I needed, I created one send channel in the mixer window for each track (6 in total), assigned those tracks (pre-fader) to the sends (-inf volum in the event page), [1] > [@AHDSR probem on volume with Loop region and release](https://qa.fmod.com/t/ahdsr-probem-on-volume-with-loop-region-and-release/13833/5): > > And created a snapshot for each layer combination I needed. Then added AHDSR mod to the Intensity knob of each snap (this way you can control attack and release time).
