Oh sorry, you also need to start up voicePlayer once.

</div>I think you can assign "null" to objects to have them garbage<br>
collected forcefully but I'm not sure there.<br>
<br>
However in this particular case there is a easy way out. Since you are<br>
dealing with linear envelope segments and sample-based grains LiSa<br>
will suit your needs perfectly (see /examples/special for docs and<br>
tutorials). LiSa will contain a single buffer for you that can be<br>
played back multiple times at various rates with per-voice start, loop<br>
and so on settings. It will handle most voice cycling for you.<br>
<br>
For a more general case there are questions here. I think grains are a<br>
especially interesting case for resource cycling as we will likely be<br>
doing rather a lot of that in the case of grains. Off list i talked<br>
with Mike (probably our residential expert on using grains in ChucK)<br>
about proposing a sensible way for using non-linear envelopes with<br>
LiSa however neither of us could come up with a coherent approach.<br>
<br>
Perhaps somebody else has ideas; the exact volume envelope of grains<br>
matters a lot for the resulting spectrum.<br>
<br>
There are, BTW, no free rides here. For voices or grains (and assuming<br>
finite computational power) we will need to somehow cycle resources.<br>
This is unavoidable. The question is how much of that should be build<br>
in and how much we will need to do ourselves. I don't think all of<br>
this can be build into ChucK without sacrificing versatility and so I<br>
don't think that arrays with some infrastructure need be such a bad<br>
option here. It may be laborious but it also forces us to contemplate<br>
in depth what we need and gives us power to specify that in a very<br>
precise way.<br>
<br>
Yours,<br>
Kas.<br>
