.. all coded in "C", right ? I couldn't find a way to do arbitrary changes
to the phasevocoder which is in the example patches, because the 
frequency-amplitude representation is optimized away from the algorithm.

So I might give this one a try.

Then the next step would be to come up with a system that allows for
arbitrary changes on this frequency-amplitude representation, which is,
except for filtering, hard to implement without without externals.
