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.
