The A-129/4 is the Slew Controller for the A-129/3 module. It has several dedicated functions and gives control over:- Manual control of the slew rate, CV Control of the slew rate with an input attenuator and choice of three functions: “Follow”, “Slew” and “Freeze”, freezing the output voltages for the duration of a gate.
The A-129/4 has three parallel outputs designed to drive three A-129/3 modules, therefore there is no need to use three A-129/4 modules for a full Vocoder system.
