Superbooth 2017 New Doepfer Module Announcements

From April 20-22, 2017 the second Superbooth takes place in Berlin.

Doepfer announced the new modules that will be on display there... with some very exciting new toys.
Some of the new products were already presented as prototypes at NAMM and are now available (e.g. the voltage controller performance mixer series A-135-4). But they will also show some new gear in Berlin (e.g. the quad VCO A-111-4, the micro keyboard A-173-1/2, the miniature stereo mixer A-138s and the low cost versions of the monster cases).

A-111-4 contains four precision VCOs with 10 octaves range and has individual controls, inputs and outputs for each VCO available as well as common controls.
After all the A-111-4 is very similar to four A-111-3 with built in output mixers for the three waveforms and a common control unit for all VCOs. Controls, inputs and outputs (individual for each and common for all VCOs): 1V/Octave CV input Octave switch (+1/0/-1 octave) Tune control (range internally adjustable by jumpers:…

Doepfer A-150-8 Octal Manual/Voltage Controlled Programmable Switches Announced

Doepfer has just released some info on their new modules for NAMM 2017 (19-21 jan.) Besides some vintage editions of existing modules, the A-135ABC VC Performance mixer modules, the A-110-6Trapezoid Thru Zero Quadrature VCO and a new A-100LC1 case (economically priced small housing with 48 HP width) there was also one other interesting new module announcement:
Module A-150-8 contains eight manually/voltage controlled switches.  Each of the eight switches has a manual control button (Man.), a control voltage input (CV), a common Out / Input (O/I), and two In / Outputs (I/O1, I/O2).  The switches are bi-directional, i.e. they can work in both directions, so can connect one input to either of two outputs, or either of two inputs to one output. 
Two LEDs show which in / output is active (ie. which is connected to the common out / input).  In addition the LEDs are used for the programming of the module: For each unit the operating mode can be selected:  Toggle or Level controlled. In Toggl…

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 s…

Doepfer A-138p/o Performance Mixer Combo

The latest addition to my modular system is the A-138p/o Performance Mixer set of modules...

Modules A-138p/o are a simple performance mixer that I use as and end-mixer for all the signals coming out of my A-100, and for merging my TB-303 audio, before it all goes into my mixing-desk.

Module A-138p is the 4-fold input module, A-138o is the output module that can be combined with one or more A-138p.
I read somewhere that the module didn't start off as commercial product, but as a personal hobby-project of Dieter Doepfer who just needed this module for himself... It did go through quite a few prototype stages before it was released in this final form.

The A-138p has 4 input channels, with separate controls and a mute
switch for each channel.
The controls are for Gain (control to adapt different audio levels -also for external signals), Level (the main volume control), Aux and Panning
An internal jumper for each channel lets you choose between Aux pre/post main Level control.

Happy New Year From PatchPierre

Hi there, it's me again... Happy New Year!

You might have noticed that I havent posted a lot in the last 2 years...
It's been a rough time for me since the sudden loss of two parents within a relatively short time-span and I really needed some time to get myself together... to set things straight, finding myself and selecting priorities... even my regular work suffered from this breakdown.

It took a while to understand it all, and to get a better grip on it, and it's sometimes still not very clear.
I think I have found a way to cope with most of it now... although the slight autism that I have (ADD-like) doesn't make it easy for, especially in crowds with lots of people I don't know...
On my journey I also (re-)discovered the beautiful woman that has always lived inside of me and that i need to accept and cherish... more on that maybe later... I'm not considering changing the name of the blog to PatchPetra.Net 😇 (...yet), but you might spot me somewhere at mod…
