[sdiy] Speaking of the Elektor Vocoder (and the Korg Vocoder)

[Paul Perry]

One advantage of a DIY analog vocoder, is that you could have a patch panel
so that the channels can be switched around. 
I think this would give a great deal of flexibility.
(note, you can do similar trickery with a digital vocoder, by using
frequency shifters or ring modulators on the controlling audio input).

Having precise filters is not necessarily an advantage, some of the most
interesting vocoder sounds have been made with filters having high resonance
and thereby giving a kind of 'ringing' sound - the frequency response of the
filter under these conditions is anything but a classical shape.

I thougt about building the Elektor Vocoder, but it is a rather big project,

and people told me that software or dsp based vocoders could be the better 
ones because of the possibility of implementing filters with higher slew 
rates. So if you compared software vocoders with hardware vocoders what is
your opinion?
