[PD] More teeth. Was: cyclone abstractions was: Nettles.

hello, I had plans to try working on a .c code for it, and my idea was to
just adapt from [comb~].
Yeah... Teeth is almost identical to [comb~]!
In [comb~] you have the same delay time for the feedforward and the
feedback. In [teeth~] you can specify different time delays for feedforward
and feedback. So you basically have only one extra time delay parameter to
include in [comb~] and... voilĂ , you've got [teeth~]!
Hope this makes it clear for you.
Cheers
