Dark Energy II Coming Soon

It looks like the long-awaited Dark Energy II will almost see the daylight.
Doepfer receives the first batch of pre-serial Dark Energy II models any time now...

After these models are tested and checked (and no major flaws are discovered), the first production-order will be placed and Doepfer can start distributing the first modules.*
A part of that first production-batch is reserved for people who pre-ordered their DEII.

Dark Energy II

To fresh you up, the main differences between the Dark Energy II and the original Dark Energy are:

- 12dB multimode filter with lowpass, notch, highpass and bandpass (instead of 24dB lowpass of Dark Energy I)
- the previous LM control of the filter becomes the filter type control (continuous crossfade lowpass - notch highpass - bandpass)
- the LM function of the filter is no longer available
- the waveform switch is used to select between saw and clipped/distorted saw (in the center position the saw is off)
- the basic waveform of the VCO is saw (not triangle like the Dark Energy I).
- because of the pure analog circuit and the temperature control it takes about 30 minutes until the VCO is in tune.
- the VCA has a exponential scale (not the combined linear/exponential scale of Dark Energy I)

Random Video: First Stage of a Modular Synth

I found this informative and interesting video on the web about basic rack/case-building... enjoy!

Video: First Stage of a Modular Synth

" Just started building my Eurorack modular synthesizer. I wanted to demonstrate that building your own "Frankenstein" system is easy to do. This video demos, the set up of the power supply and bus board, and a single VCO module."

Nokia App-Update

Although the platform seems to be slowly dying (i recently made the last changes to it...ever) my FREE PatchPierre app for NOKIA phones ( S40, S60, Symbian ) is still available.

Basically this PatchPierre Mobile application is an RSS-feed(s) reader plus NetPierreTV YouTube videoplayer.

Over 6600 downloads/installs already in 157 countries...
(and more than 1000 downloads of the latest version in the last two weeks)

The app will soon be available for the latest NOKIA Asha Touch devices; the Asha 305/306/308/309/311

You can find all versions of the PatchPierre app in the NOKIA store at

http://store.ovi.com/search?q=patchpierre

Don't worry if you don't own a NOKIA device.

PatchPierre.Net also looks good on your Android, iOS and Windows phone or tablet via the special mobile version of the app at http://oviappwizard.com/mip/plus/list.jsp?&id=184288 (for as long as it lasts), 
or the original mobile version of the blog via http://patchpierre.blogspot.nl/?m=1 , or keep on track with the the RSSfeed in your favorite RSS-reader or applications like Flipboard.

Modular In A Picture Frame

A great idea for a nice modular case can be found on http://groanmaster.blogspot.nl/

This project by Andrew Dobbels involves a real picture-frame and a 208 HP Eurorack with various modules.
You can find the making-of pictures on his site with explanatory texts, so you can build your own.

Doepfer USB/CV/Gate/MIDI Converters Update

A little bit more info (by Dieter himself) on two upcoming Doepfer modules popped up in the Yahoo Doepfer Usergroup today.

It said that the A-192-2 Dual CV/Gate-to-MIDI/USB Interface is in the starting blocks and will be included with the next (fall 2012) production series.
Module A-192-2 contains two independent CV/Gate-to-Midi/USB interfaces.
Another product that almost reached the production stage is the A-190-5 four voice polyphonic Midi to CV/Gate interface that will probably be included in the last production series in 2012.

The A-190-5 will have 12 CV and 4 Gate outputs, and different modes (e.g. unisono, four-fold monophonic, different four voice polyphonic modes)
The hardware of the A-190-5 module is ready and Christian is working on the firmware.
Though it was planned to use 12 bit DA converters Doepfer thinks about 8 bit converters to reduce the price a bit.
"12 bit converters don't seem to have any advantage because the module only converts 7 bit midi data into CV (no software LFOs or software envelopes or software glide) and in this case 12 bit DACs

are wasted money because the last 5 bits are not used.", according to Dieter.

The estimated price for the A-192-2 is approximately 130 Euro, expect to pay around 300 Euro for the A-190-5.
Price and release date are still without obligation

A-160 to A-161 Connection

Module A-161 is an eight-step Clock Sequencer which is internally connected to the Clock Divider (A-160).

Eight outputs are sequentially switched by the clock signals from the A-160 and can act, for instance, as sequential rhythmic triggers for an envelope. 

A question that popped up in the Doepfer A-100 Usergroup on Yahoo some time ago was how the A-160 and A-161 should be connected together.
This can be found in the A-161 Manual (PDF) ,but i think this post (and picture) will provide the info you need.

A-160 <> A-161 connection

The A-161 must be positioned directly to the right of the A-160.
Join the two modules with the supplied 10-way ribbon cable.
Use the upper 10-way socket on each module.
Make sure that the ribbon cable is not twisted, and that the colour-coded section is oriented the same on both modules.
Only join the A-160 to the system bus! 
Leave the lower 10-way socket on the A-161 unused.

Pay attention not to damage one of the parts on the boards (especially none of the transistors).
If necessary, you may bend the transistors a little (carefully) to plug in the cable.
