After the A-124SE Doepfer WASP special edition was announced almost 2 months ago, Doepfer now releases the A-110-4SE Zero-Thru Special Edition module.
From about middle of October a special edition of this Quadrature Thru-Zero VCOs A-110-4 will be available as A-110-4SE.
The special edition is equipped with a blue anodized front panel and white knobs.
The price will be 140 Euro
Blue and white seem to be the colours of the Bavarian flag... #Oktoberfest reference?
A-100SSB is a combination of power supply and bus board with 8 connectors for A-100 modules. Planned for applications with up to 8 modules and a max. current of 380 mA. A-100SSB is available as ready built and tested unit.
A-100SSB Prototype I
These are the most important features:

- safety cover at the bottom side (covers all elements that lead mains voltage)
- on board fuse
- 8 bus connectors
- LED displays for +12V, -12V and +5V (+5V are available only if e.g. the 5V adapter A-100AD5 is used)

- several 3mm holes for mounting the unit on a rear panel or bottom plate
Planned for ca. Oktober 2015 / ~ October 2015 / for ~ Euro 75.00
Raul Pena published new videos demonstrating the A-136 Distortion/Waveshaper Module
Module A-136 is a distortion and waveshaping module with extensive control possibilities. The incoming audio or cv signal is internally divided into 3 sections:
- positive component of the signal with adjustable clipping level (even externally via jack socket) and positive or negative amplification (+/-) of this component
- negative component of the signal with adjustable clipping level (even externally via jack socket) and positive or negative amplification (+/-) of this component
- original signal with positive or negative amplification (+/-)
Different settings of 5 distortion/waveshaping parameters enable a lot of very complex and extreme waveform modifications. The range of modifications reaches from simple soft or hard clipping to completely altered waveforms where the original signal is no longer recognizable.
The sketch below shows only a few examples when using a triangle as input signal.
Applications: audio distortion (especially in combination with filters very interesting), waveform modification for audio signals as well as for control voltages (LFO, ADSR, random etc.).

Module A-168-1 is a pulsewidth modulation generator (PWM Module).
It derives a rectangle signal with adjustable pulsewidth from an external triangle, sawtooth or sine wave.
The external signal can be an LFO, VCO or any other signal with falling/rising slopes (e.g. ADSR). In addition the pulsewidth can be modulated by a CV signal (e.g. LFO or ADSR).
The typical application is the generation of a rectangle signal with PWM from VCOs or LFOs which do not yet have this feature (e.g. A-110-4, A-145, A-147-2, A-143-4, A-143-9).
The module is equipped with these controls and in/output:
- Manual PW control (PW)
- PWM CV Input with attenuator (PWM)
- Signal input (In)
- Output with LED control (Out)
- Inverted Output with LED control (/Out)
- Internal trimming potentiometer for PW (is adjusted for symmetrical 50:50 rectangle when the manual PW control is at center position)
- Internal trimming potentiometer for PWM range (is adjusted so that the manual PW control covers the full PW range 0 ... 100%)
- The trimming potentiometers are required to adjust the module for best operation for signals with different DC offsets (e.g. unipolar/bipolar signals) and different signal levels.
Normally the module is assigned to another module because the trimming potentiometer have to be readjusted when the input signal changes (unless the signals have nearly the same DC offset and level)
(planned for November 2015, price ~ Euro 50.00, price and release date are still without obligation)

Quite unexpected, Doepfer announced a black A-124 Wasp filter with yellow knobs today.
This module comes as a limited edition and will be available through your local dealers. (order no. A-124SE)
According to a Doepfer interview with the Sud-Deutsche Zeitung the first batch sold out (to distributors) within 24 hour.
Great marketing-idea by Doepfer IMO, especially to promote the recently announced colored knobs. All kinds of color-schemes are possible now.
" The frequency of the input signal (preferably the rectangle output of a VCO) is divided by an integer factor N (N = 1, 2, 3, 4 ... up to 32). N can be adjusted manually and modulated with an external control voltage (e.g. from LFO, ADSR, Random, MIDI-to-CV, Theremin, Light-to-CV, analog sequencer) with attenuator.
The control input has polarizing function, i.e. the manually adjusted dividing factor can be modulated upwards or downwards. The basic idea of a polarizer is described in the modules A-133 Voltage Controlled Polarizer and A-138c Polarizing Mixer.
A-163 Frequency Divider
The output waveform is rectangle with 50% duty cycle. Unlike the A-115 with fixed dividing factors
Applications: dynamic voltage controlled frequency division of audio signals or modulation signals. More details concerning frequency division of audio signals can be found in the Trautonium or A-113 information.
Inputs: CV In, Audio In (rectangle)
Output: Audio Out (resp. rectangle modulation CV out after modification)
Controls: Manual N, CV attenuator
After a small modification (a capacitor has to be shortened or replaced by a wire for DC coupling) the A-163 can be used for low-frequency control signals too.
Remark: From 2007 the module is equipped with an additional jumper at the bottom side of the pc board. This jumper is used to select DC coupled (jumper installed) or AC coupled mode (jumper removed).
If the module is used to divide slowly changing signals (like clock, trigger, gate or rectangle signals of an LFO) the DC coupled mode has to be selected. For audio signals the AC mode is recommended."
(2, 4, 8, 16) the dividing factor of the A-163 is voltage controlled and can be any integer value between 1 and about 20 (but only one output). In contrast to A-113 the dividing factor of the A-163 is voltage controlled and the output waveform is rectangle (the A-113 has 4 sawtooth outputs with 4 adjustable but not voltage controlled dividers).

" A short overview of the basic features of the A-163 VC Frequency Divider. A short audio demonstration is provided.
Following the many requests in the Doepfer Yahoo-group, Doepfer announced today that an A-180-3 Dual Buffered Multiple will soon be released.
Module A-180-3 is a dual buffered 1-in-3 multiple.
The signal applied to the input socker appears as a buffered signal at the three output sockets.
Each output has it's own buffer, i.e. the three output sockets are not simply connected to each other. The lower output of the upper unit is normalled to the input of the lower unit.
That way the module works as a single 1-in-6 buffered multiple provided that no signal is applied to the input of the lower unit.
Application: copying/buffering of control and audio signals.
Update by Dieter: "the prototype pcb of the dual buffered multiple (A-180-3) arrived and has been tested. As expected no problems occured. The
module will be released about September 2015. The price will be the same as the A-138u because it very similar (i.e. Euro 50)"
ps Doepfer is closed from June 20 until July 05, 2015. No shipping, no helpdesk, no repairs during this time.
