Modular Vocoder

A-129 /3/4

% Slew CV

Input % is where the CV should be patched in to

control the slew rate. The amplitude of the CV can be

set with the attenuator

if required.

& Slew Control Outputs

Sockets

are the slew limiter controller’s outputs.

They’re internally connected (a sort of mini-multiple),

and are designed to provide the control voltage to the

A-129 /3.

Connect one of the outputs to an A-129 /3 control

input.

Basic layout

Fig. 4 shows the standard layout for using the

A-129 /3 and A-129 /4. The A-129 /3 is inserted into

the control voltage chain, sandwiched between the

analysis and synthesis sections.

For total control of a 15-band vocoder, you need three

A-129 /3 modules. It’s quite possible to control the

slew limiter function of these three with one Slew

Limiter Controller A-129 /4. There’s also the option,

though, of using up to three, to treat different bands of

the vocoder in different ways.

The standard layout in Fig. 4 provides the following

control functions:

• CV to control the level of one or more vocoder

channels or bands (using the attenuator),

•

Smoothing the transition between vowels (slew li-

miter function),

• Vowel hold (freeze),

• Transposing vocoder channels (offset).
