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.

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.

MusicMesse Reports by @Flixxx (Playlist)

MusikMesse 2015 in Frankfurt took off today, with the Roland modulars/modules as the most talked about eurorack releases. Read all about that on the other blogs ;-)
Pretty refreshing to see this year are Felix' (The Tuesday Night Machines) excellent video-reports from the floor... Here's his playlist, enjoy!
(it looks like he is still adding episodes at the time I write this, so feel free to chech this blogpost again tomorrow or later this week)

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

Nano Rand

Qu-Bit Electronix has published more info and a video about their latest module, the Nano Rand.

"Nano Rand is a sample and hold, noise source, and random voltage generator in 4 HP.
It takes inspiration from and improves upon the analog concept of a random voltage module; moving forward in leaps and bounds into the digital domain.
At its­ core is an 8 bit microcontroller which allows for an extremely versatile, and more importantly, musical type of random.

- 4 switchable random voltage algorithms
- Can be internally or externally clocked
- Random gate source that generates musical derivatives of incoming clock
- Generates random frequency audio rate square waves allowing it to be both audio and control source
- Random voltage can be unipolar or bipolar

Specifications:
Width: 4hp
38.1mm (Skiff friendly)
Power: 60mA
Price: $190.00"

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...

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 provides single 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!)

Update January 16 2016:

Dieter in the Doepfer Yahoo Usergroup:

"The A-157 are now in production and the first batch will be shipped ~ middle of February. But it depends upon the orders of your dealer when they arrive at your dealer. As far as I know the first batch is already sold out."

Note: I replaced the Version 2 frontpanels by the final Version 3 ones
