York is right.

as the analysis module (A129/1) sends cv's to the cv inputs of the synthesis module(A129/2), you can basically use whatever dc-coupled module you can think of, to mangle the cv's coming from the analysis module.

for example, you can even use a Doepfer A187-1 vc-DSP (which is dc-coupled), to manipulate the cv's coming from the A129/1 !

Hi!



The great thing about the Doepfer vocoder is that the individual analysis bands

are so easily accessible. So why not add some VCA's and LFO's and modulate some

of the analysis bands Or go wild, get 16 VCA's and LFO's and do it to them all!



Get a multiple and split one of the analysis bands into several synthesis

inputs; conversely combine several bands into one with a mixer. Inverters are

nice, so is a joystick to control some aspects.



Grab a ringmodulator or some wavefolder and do unspeakable things to one of the

helpless analysis bands.



You said that you have no need for an oscillator but the voiced / unvoiced

detector needs some noise inputs as well (can be external too, of course).



As for filters, a vocoder is basically a filterbank on steroids so I'm not sure

how much mileage you'd get out of a dedicated unit. Otherwise, filters are

great, can't have enough of them.



Have fun!



York

Subject: 1 Modules for increasing VOCODER functions



Hello

I need your help for increasing in interesting ways the functionality and

possibilities of my doepfer vocoder.

I'm not very deep in knowledge of doepfer modules because my interest is

focalized in to the analog vocoders.

In my Eurorack I just have:

A-129\1

A-129\2

A-129\3

A-129\3

A-129\3

A-129\4

A-129\5

A-119

Some holes are in the rack and them want to be filled!

The carrier signals will came ever from external sources, so I'm not interested

in VCO modules and complementar.

Can you help me to find interesting combinations for increasing the vocoder

function

For example:

other two A-129\4 could be required for completing the slew limiter controlling,

but it seems to me not a big upgrade, another A-119 sometimes had to be usefull

for having one for carrier and one for formant, but I usually use an external

mic amp....

Also the matrix module (3 of them will be required! if I'm not wrong) was a

possibility for an easier controll of the band filters but it will not gain or

ampliate the "sounds" possibilities of the vocoder.

What's about a divider Will be it usefull in the vocoder

Or what's about the A-128 filterbank Or a filter

Please give me your suggestion, for gain the flexibility of the vocoder and

implement its functions, also in experimental and original way.

What do you suggest

Many thanks to all in advance for your reply!

Best regards.
