HI! Not the envelope module, directly....
but you might be able to use the step module for simple synced triggering.
alternatively you can use the pattern module to trigger an envelope ?
It was just to modulate a filter cut off, and the step module is allright...I had just to use sleptime and slope correctly. By the way, i've discovered, that i can set them for each step independantly, by using right mouse click.
RTFM!
Although i believe that it could be a great feature to be able to trigger envelope...
