Paper circuit controlling a Doepfer A-152 sequencer, details below:

Hello ! My name is Frederic Gerchambeau. I have made this movie and this music. The music has been made using a Doepfer analog modular system including an A-152. Enjoy !
I am a (proud !) member of the french association PWM (Patch Work Music) :

Groovesizer Alpha & Doepfer Dark Energy: random patterns

September 10, 2013 · Posted in Uncategorized · Comment 

The Groovesizer (http://groovesizer.com) with Alpha firmware is a DIY 32-step sequencer and synth. In this video, it’s controlling a Doepfer Dark Energy via MIDI. The video shows off the random pattern generation of the Groovesizer Alpha (major, minor, pentatonic, chromatic).

The Groovesizer (pronounced groove-a-sizer) is a DIY 8-bit audio platform. It’s a musical chameleon that can take on a number of different roles from sequencer to synth, drum machine, or midi controller. Exactly what the Groovesizer is at a given moment depends on the firmware it’s running. Existing firmware can be freely hacked, or new firmware developed using the beginner friendly Arduino IDE. Firmware is loaded to the board directly from the Arduino IDE, either via an AVR ISP programmer, or by flashing the Atmega chip on an Arduino board and swapping it out.

The Groovesizer is based around a custom PCB that features 6 potentiometers and  5 rows of 8 tactile switches and leds  (4 rows for the sequencer / trigger buttons and 1 row dedicated to control functions). It features an integrated Arduino clone, an 8-bit DAC option, an LM386 amp output, MIDI in/out/sync and is configurable to work with some of the most popular existing Arduino audio projects.

Furthest along in its development is the Alpha firmware which features a 3 oscillator monosynth attached to a 32-step sequencer with 112 memory locations to store patches and patterns.

Doepfer Dark Energy & minicase with two VCOs A-110, a mixer A-138 and a multiple A-180

Wouter van Veldhoven has shared this multi machine video, details below:

This basically put almost every machine in my studio in operation,
Everything is controlled by a doepfer a100 system + some home-brew modules, in combination with some self made step sequencers build

303 ENERGY – Custom built sequencer

July 5, 2013 · Posted in Uncategorized · Comment 

Try out of the custom built 303 Energy which is a sequencer synthesizer based on two Doepfer A-111-5 (Dark Energy) and Acidlab Autobot. It has two theremins to control the filters.

303 ENERGY 03

On the left side of the sequencer and first synth there is a theremin controller (A-178) to control the MS-20 filter (A-106-1 extreme) and the Wasp Filter (A-124) On the right side of the sequencer and second synth voice there is also a theremin controller (A-178) to control the 303 filter (A-103) By approaching the antenna’s with your hands you can control the filters. Next to the two theremin controllers there is also an A-198 Ribbon control board to connect a ribbon controller. To invert the control signals (for instance VCA up in stead of down) there is a voltage inverter (A-175) next to the right Theremin controller. For now it gets its power through a XLR connector on the left side (+12V, GND, -12V) from a 1200mA external powersupply.

Creating music with Moog Rogue, Roland Alpha Juno 2, and Doepfer A-100 synths

Background video description:

This is a two step sequence using the ef303.
I am using the doepfer quantizer, the clock sequencer and two envelopes on the filter (adsr and ar) to make it come allive.The ar generator is triggerd by the clocksequencer and the adsr is triggerd by the ef303.
And i also use some delay .
And i jam along on the rouge and juno.

In-depth exploration of the KOMA BD101

June 10, 2013 · Posted in Uncategorized · Comment 

The KOMA BD101 is a complex (short) Analog Delay & Amplitude Modulation unit that can be used for filtering and treating audio signals; the very short delay time closes every “standard” application, but opens a whole landscape of sonic crushing and underclocking distortion. Pretty Wild. The IR sensor is very sensible to strong lights for shooting; so, on this video, its sensibility is not so strong than in the real life.

KOMA BD101 amplitude modulating Doepfer Dark Energy; Dark Time retriggers synth eg and BD101 is AMing signal for a rhythmic interaction; short delay and underclocking of BBD as usual.

The short BBD into BD101 is modulated with LFO triangle/square wave out from Doepfer Dark Energy. A lot of harmonics and – when underclocking takes act – a lot of severe audio changes. Not a standard delay, but a complex sound sculpting machine.

Doepfer A124 Wasp Filter LP/BP/HP/Notch Demonstration

May 17, 2013 · Posted in Uncategorized · Comment 

A continuation of the exploration of the Doepfer A124 Wasp Filter. The Notch, Lowpass, and Highpass portions of the Doepfer A124 Wasp Filter are explored. In the next segment this filter is compared to the Doepfer A121 Multimode Filter. Sound and Video by Raul Pena.

MFB Urzwerg & Synthesizerscom & Dark Energy

May 10, 2013 · Posted in Uncategorized · Comment 

Continuing on from yesterday’s video featuring the MFB Urzweg – here’s a new video hooking it up with a full blown modular system

MFB Urzwerg Pro is controlling four separate synth channels on Synthesizers.com Modular System. Each row sends CV for oscillators and Gate for Envelope(s); MIDI Out from Urzwerg is transmitting MIDI Clock to Acidlab.de MIAMI Analog Drum Machine. TC Flashback Delay (set at eight dotted lenght) is connected to Aux Send on mixer. Far on the left of picture, the 960 Step Sequencer acts like a “real time preset voltage source” for full four sequences transpose.

MFB Urzwerg Pro step sequencer is controlling Doepfer Dark Energy mk I analog synthesizer. CV 1 goes on pitch, CV 3 goes on Cutoff, CV 4 goes on Amp; Gate 1 goes on EG Gate. LFO 1 Square wave out from Doepfer goes to External Clock on sequencer.
