[chuck-users] soft kill

Hello, I was having some fun with delays in ChucK when I should have been paying attention in a meeting and ran into something I may have asked about before -- is there (or should there be) any way any way to soft kill a shred, either by ramping down its gain or by waiting until the shred is no longer sending output to dac? If I $ chuck - 1 something that is running it kills it immediately, and if I don't advance time long enough explicitly at the end of a delay example, the nice feedback tail gets abruptly cut off. E.g. https://github.com/heuermh/lick/blob/master/examples/mfm2.ck (doesn't require LiCK to run) michael
