Colored Doepfer Knobs

Yay... Doepfer decided to produce and sell knobs in multiple colors.
The modules are still delivered with grey knobs.
Because of logistic reasons it's not possible to deliver modules with different colored knobs, but the customer is able to order the knobs separately and replace the grey knobs by the new ones as the knobs are simply plugged on the potentiometer shafts.

The colored rotary Knobs, diameter 15 mm, height 15 mm, for 6 mm axis with 18 teeth, can be used also in other products like MAQ16/3, Dark Energy or Dark Time.

You can find the new knobs on the price list in the Doepfer website's spare parts section...

Doepfer A-111 High-end VCO 2 Video Tutorials by Raul Pena

For his next Doepfer tutorial video series, Raul Pena returns to the classics...

A-110 Standard VCO vs A-111 High-end VCO(2)
Module A-111-1 (VCO2) is a voltage controlled oscillator. 
The VCO has a range of about 12 octaves, and produces four waveforms simultaneously: pulse (rectangle), sawtooth, triangle and sine waves. 
The VCO's frequency is determined by the position of the range switch, tune and fine tune controls, and the voltage at the two pitch CV inputs, CV 1 and CV 2. Footage (the octave of the fundamental) is set by the Range control, which has seven octave steps. 
The Tune control is used for coarse tuning, and the Fine control for fine tuning of the VCO pitch. 

The A-111 can be modulated by both exponential and linear FM (frequency modulation). 
You can control the pulse width of the square wave either by hand, or by voltage control - Pulse Width Modulation, or PWM for short.
The A-111 also has inputs for Hard Sync and Soft Sync.

As the special circuit CEM3340 used in this module is no longer available the module has to be discontinued.

Doepfer A-106-5 12dB SEM Filter Tutorial Videos by Raul Pena

While I was gone, Raul Pena kept on making new A-100 video tutorials.
Here's the next series (now presented here as a playlist instead of weekly updating a blogpost), showing you all the ins and outs of the A-106-5 SEM Filter.
A-106-5 12dB
SEM Filter

Module A-106-5 is a 12dB multimode filter that is based on the filter circuit of the Oberheim SEM module.
The filter is equipped with a band pass output and a combined low/notch/high pass output.
For this output a control knob defines the relation between low and high pass signal. 
If both signals appear at the same level (i.e. middle position of the Mix knob) one obtains a notch filter. Otherwise the low or high pass signal predominates. 
The module does not feature self oscillation in contrast to most of the other filters of the A-100 system. 
The module generates a distorted audio signal if the level control is set to about 50% (i.e. center position) or more with A-100 standard signals like VCOs.

Inputs:
Audio In, CV1 In without attenuator, CV2 In with Polarizer
Outputs:
Bandpass Out, Low/Highpass Mix-Out
Controls:
Audio Attenuator, CV2 Polarizer, Frequency, Resonance, LP/HP Mix

New Doepfer A-157-1/2/3 Trigger Sequencer Prototypes

Doepfer has published another (4th?) collection of new prototypes of the A-157-1/2/3, and seem to be preparing it for a NAMM 2015 lauch...
I have been following this project since February 2011, and i am still looking forward to this one...

The graphics have changed, the A-157-1, the main trigger part with 160 buttons and 160 leds, has a nice black-and-silver colorscheme, and the function buttons on the right side have been labelled now...

A-157-1 Trigger Sequencer
A-157-2
Trigger
Outputs
A-157-3
Control
Inputs
The full subsystem will still contain several modules:

- The LED/button matrix module A-157-1,
It seems to feature some nice functions like Invert Row (when shift left and right are operated simultaneously) have been added for each row, plus mute and select for each track, shift pattern, first/last step and different running modes (fwd/back/pendulum/random)

- The trigger output module A-157-2
The A-157-2 now provides double outputs for each track

- , and one of the control modules (A-157-3, A-157-4 ...)
A simple controller with basic functions like start/stop, reset and clock, which can  be controlled via input triggers or the dedicated push-buttons.

Release date: ~ early in 2015 (NAMM!?)
(only A-157-1 ... 3, so far there is no release date available for the planned module A-157-4 and the stand-alone unit Dark Flow!)

Doepfer A137-2 VC Wave Multiplier II Tutorials by Raul Pena

A-137-2 Wave Multiplier II
Back in August of this year Raul Pena published his series on the Doepfer A-137-1 Wave Multiplier module (11 parts!)

Now he's back with the first tutorial videos starring the follow-up to this module, the A-137-2.
The A-137-2 is another version of a wave multiplier.
In contrast to the A-137-1 Wavemultiplier I the A-137-2 generates four phase-shifted copies of a VCO signal applied to the audio input. The four shifted signals are added to the original signal to obtain a fat sound similar to five independent VCOs.

Doepfer A-160-5 VC Clock Multiplier / Ratcheting Controller Announced

Doepfer A-106-5
Doepfer keeps on announcing interesting new modules;

" Module A-160-5 is a voltage controlled clock multiplier.
The incoming clock signal (socket Clock In) is multiplied by a factor that depends upon the control voltage on socket CV In (0...+5V) and the position of the Mode switch. 
The multiplied clock signal is available at the socket Clock Out. 
According to the position of the Mode switch different clock multiplying factors are assigned to the control voltage. 
With 0V CV no clock output is generated. 
With increasing CV integer factors (left position of the mode switch), power of two factors (middle position) or a mix of both (right position) are obtained. 
Nine LEDs are used to show the currently selected multiplying factor. 
In addition two LEDs are used to display the incoming and outgoing clock signal.

The module can be used for all kind of clock multiplying applications. 
One important example is the generation of so-called ratcheting sequences. 
The band Tangerine Dream is famous for this kind of sequences. 
A normal sequencer generates only one gate signal per step. 
A ratcheting sequence may have also more than one gate pulses per step. 

This function can be obtained by using the A-160-5: one CV output of the sequencer is used to define the number of gate pulses per step. 
If the control of the step in question is fully CCW the generated CV is 0V and no gate signal is generated (mute of the step). 
When the control of the step in question is turned clockwise one, two or more gate pulses are generated depending upon the position of the mode switch and the voltage generated by the CV at this step."

Price: ~ Euro 100.00
Release date:  ~ March 2015

Animodule V9A VC Sequencer / Waveshaper / Complex Envelope Demo by @DivKid

Animodule V9A
DivKid's latest Eurorack tutorial video is all about the Animodule V9A Voltage Controlled Sequencer / Waveshaper / Complex Envelope

" The V9A is a powerful animal to add to your sequencing arsenal.
Send your CV to the CV In. As the Voltage increases the sequence steps forward.
As the voltage decreases the sequence steps back.
Scale and adjust your input voltage to taste with the Onboard Attenuator and Offset.
Control the Output CV with an individual Potentiometer for each step.
When a step changes, a 10MS trigger is sent to it's corresponding switch. If the latching switch is depressed it allows the trigger to pass to the Trigger Out.
There is a switch per step for slew (portamento/slide).
and a Potentiometer to control the Slew Amount.
There is also an input to allow gated control of when the slew turns on and off which will work in conjunction with the switches."

Width: 14HP Depth: 39mm

Video: Animodule V9A

" A great module for some custom modulation even sequence, bendy LFO (through on board slew), gate trigger, CV sequencing. All sorts going on.
As always fire away with any questions and hit like and subscribe for more videos every week."

MakeNoise Richter Wogglebug Update

MakeNoise gave their Richter Wogglebug a nice update.
"The "WoggleBug" is a random voltage generator, originally designed by Grant Richter of Wiard Synthesizers.

Richter Wogglebug Re-design
It is a continuation of the "smooth" and "stepped" fluctuating random voltage sources pioneered by Don Buchla within the Model 265 "Source of Uncertainty," expanding it to include the other-worldly Woggle CVs (stepped voltages with decaying sinusoids edges). 
The Wogglebug is a very musical random voltage generator where it is possible to synchronize all random signal to a Master Clock. 
Guaranteed to unleash your synthesizer's ID MONSTER!

The Wogglebug features ( check out the new features below the video):
- Complete Complex Random Voltage system, no external modules necessary
- Two VCOs, Phase Lock Loop, Lag Processor, Clock, Burst Generator and Sample & Hold
- Generates 7 Random Signals simultaneously: Smooth VCO, Woggle VCO, Ring Mod, Stepped, Smooth, Woggle, Burst
- Generates ultra stable, voltage controlled Master Clock
- External inputs for S&H (Heart IN) and Ring-Mod (Influence)
- Disturb button adds performance element
- Wonderful for modulating the Phonogene and DPO

Video: Make Noise Richter Wogglebug

" The Wogglebug is a random voltage generator, originally designed by Grant Richter of Wiard Synthesizers. It is a continuation of the "smooth" and "stepped" fluctuating random voltage sources pioneered by Don Buchla within the Model 266 "Source of Uncertainty."
New features in the Richter Wogglebug:

- A much more stable clock output with the widest frequency range yet seen on a Wogglebug. The clock now goes up to about 200Hz, allowing the Control Voltage and Gate OUTputs to be heard directly as different flavors of analog and digital noise.
- In previous Wogglebugs, the clock had been locked to the internal Sample and Hold Circuit. Now, with the Richter Wogglebug, the clock can be freed by the independent External Clock INput or the Disturb Button. Regardless of what is happening at these control points, the Internal Clock OUTput will continue to run at the specified rate, keeping it open for use as a Master Clock at all times.
- The Disturb Button allows the Sample and Hold Circuit to be clocked manually: press to sample, release to hold. When the Wogglebug is running fast, this can slow it down. When running slow or not at all, this kicks it in the ass and delivers the next set of random values.
- The Smooth VCO is a brand new waveform, Sharktooth.
- The Influence input has a greater effect on all parts of the Wogglebug's psyche than the previous Ring Mod input.
- The Burst output is more active and ALL portions of the Wogglebug are more responsive to control and touch."
