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

New Malekko Modules Are Now Shipping

Buffered
Multi

Mix 4

Unity
Mixer

The people at Malekko have been crafting a new series of Eurorack modules from affordable creative synthesis designs to performance tools

They are very happy to announce the first three in this series are now available through your favorite modular retailers!

MIX 4

This 3hp 4-channel mixer is the first to literally fill the odd hp gap - Harvestman users rejoice!
MIX 4 also features DC coupling for mixing low frequency as well as CV.

UNITY MIXER

The 2hp Unity Mixer is a little powerhouse of unity gain mixing capability. 2 sets of 3 inputs (1 out per set) offers up your basic configuration, then hit the SWITCH button to allow for 6 total inputs (1 out). Unity Mixer also supports CV so the SWITCH button makes this module a great option for rerouting combinations of signals on the fly and is perfect for live performance!

PERFORMANCE BUFFERED MULT
The 2hp Performance Buffered Mult features 2 sets of 3 outputs (1 audio or CV signal in with 3 buffered outs) and the SWITCH button allows for a total of 6 outputs without signal loss for on the fly multiplying.

Modular Wild Presents - Evaton Technologies RF Nomad Shortwave Radio Module

Raul Pena started a new Modular Wild series about the Evaton Technologies RF Nomad Shortwave Radio Eurorack Module.

Video 1: Modular Wild Presents Profile-Evaton Technologies RF Nomad

" A short overview of some of the basic features of the RF Nomad.Sound Demonstrations to follow. Sound and Video by Raul Pena."

Video 2: Modular Wild Presents SOUNDS-Evaton Technologies RF Nomad

" A short description and sound demonstration of the Evaton Technologies RF Nomad. includes shirt demonstration of modulation."

New episodes will be added here weekly

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."
