Doepfer A-135-4A/B/C Voltage Controlled Performance Mixer Modules Announced

In a previous blogpost I was rather excited about my own new A-138p/o Performance mixer combo.
I bought i just right before I knew that Doepfer was working on a voltage controlled version of this module...

On first impression, the new A-135-4A Voltage Controlled Performance Mixer looks quite the same as the non-cv-controllable A-138p Performance Mixer, only with extra LEDs for displaying the incoming CV voltages for all parameters (except Gain).

Module A-135-4B is the CV-input module, where 16 different control voltages can alter 16 parameters on the A-135-4A Mixer... The modules must be connected via an int 20pin ribbon-cable.

Module A-135-4C is a four-fold envelope follower with adjustable attack and release time for each channel.
The main function of the module is to derive four envelopes from the A-135-4A audio input signals. These voltages can be used to control parameters of the main module A-135-4A via the CV input module A-135-4B2. Typical applications are ducking (e.i. the signal of one channel is used to mute another channel more or less), as well as compressor and expander functions.

The modules of the A-135-4 series can be combined with the (non voltage controlled) mixer modules A-138o/p so that these can be used as output module for the A-135-4A. A-135-4A and A-138p can be connected together to the same A-138o to obtain e.g. four fully voltage controlled channels (A-135-4A) and four manually controlled channels (A-138p).

This combo will probably available before spring of this year.
