Doepfer A-136 Distortion/Waveshaper Tutorial Videos by Raul Pena

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.).

Doepfer A-166 Dual Logic Video Tutorials by Raul Pena

Raul Pena just published the first tutorial video on the Doepfer A166 Dual logic module.

The A-166 is a Dual logic module with 3 inputs for each unit.
The logical states of the inputs ("1" = high / "0" = low) are linked together in 3 ways: AND, OR, EXOR (exclusive OR). The three functions are available simultaneously at three outputs with LED display of the output states.

Additionally two inverters are avaliable to obtain the inverted functions NAND, NOR and NEXOR.
The sockets of each triple unit are "normalized", i.e. the switched contact of socket 2 is connected to input 1 and the switched contact of socket 3 is connected to input 2.
Provided that no plug is inserted into socket 1 resp. socket 2 the socket is connected to the input above it.
This simplifies the usage of the module when only 2 signals are combined. E.g. the logic functions AND and OR have different neutral input levels ("1" is the neutral state for AND, "0" is the neutral state for OR).

Here's the playlist , future videos will be added automagically every week on Thursday or Friday.

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-112 Sampler Modular Digital Delay by LESINDES

Animodule SOB Filter Videos by @DivKid

It's good to see that more and more people start making really interesting Eurorack tutorial videos lately.

DivKid started a new series last month but i kinda missed it back then.

Here's a nice set of videos with Animodule SOB Filter tutorials.

Video 1: EURORACK MODULE - Animodule - SOB Filter Part 1

" The Animodule SOB filter is a pretty amazing bit of kit, 2 inputs that can clip with a wavefolder, state variable filter and tonnes of personality and character. It can handle smooth well but for me excels at more driven and characterful filtering. It also passes CV acting as a slew limiter and self oscillates creating a crude oscillator, some heavy percussive thumps and hardcore kicks along with going really slow to make for a useful LFO should you run out mid patch.
Subscribe to the channel for more and always feel free to comment."

 

Video 2: EURORACK MODULE - Animodule - SOB Filter Part 2

" Here's part 2 of the SOB Filter overview video. The SOB is a great state variable filter (with built in wavefolder) for eurorack modular systems from AniModule.
Any questions or anything feel free to comment."

Video 3: EURORACK MODULE - AniModule - SOB Filter's Wavefolder
" Here's a more in depth look at the wavefolder built into the AniModule SOB filter. It's a great filter but (hopefully) as you'll see in the video the wavefolder is great too. Here's some oscilloscope action of analogue waveforms (static and amplitude modulated) going into the unit with external and internal mixing along with modulation to create some moving and morphing wavefolding.

Modular Analog Music and Tutorial Videos by @Flixxx

Felix from Germany (@Flixxx) has uploaded several highly interesting tutorial-videos last week, showing the more interesting/alternative/creative ways of using Eurorack modules.
They are not all about Doepfer, but he shows modules of all kinds of Eurorack brands and he does some nice and clear narration with it.
He even plans to do more of those quick looks in the future, so keep an eye on his YouTube channel.

Video 1: Doepfer A-160 Clock Divider as Sub-OSC/Frequency Divider (Eurorack Modular Synth Demo)

" A short video, showing the Doepfer A-160 Clock Divider Eurorack module being used as a frequency divider/square wave sub oscillator. This works by feeding the trigger input a VCO signal (either a square wave or saw wave) and using the division outputs (/2 /4 /8 etc.) as square wave VCO outputs. If you have any further questions, please post them below :) Thanks for watching!"

Video 2: Intellijel uVCF as Saw Wave VCO (Eurorack/Doepfer Modular Synth Demo)

" Another Modular Synthesizer video! This time I'm talking about how to use the Intellijel uVCF multimode filter module as a sine, saw and spike/rectified wave VCO. If you have any questions or comments, please post them below :) Thanks for watching!"
