[PD] controlling stuff with tables

[andy graybeal]

is there a way to make this envelope shorter ... i can hear the loops 
fading in and fading out, it would be neat if they only had something 
like a ms crossfade in stead of a few seconds, i don't know if this 
would cause clicks. but it seems like crossfades around 30ms are okay.
i'm a beginner sort of, and i happened to be gawking at the [-~ 
0.5]--[*~ 0.5]--[cos~] just now.. thinking that it was the culprit of 
why my samples where fading in and fading out...

thanks,
andy
