New Doepfer Announcements

Doepfer released preliminary information about two new modules.

The A-190-8 is a MIDI/USB to Sync interface.
Basically this module divides the incoming MIDI or USB clock messages into smaller steps.
You could see it as a modular version of the MSY2 MIDI-to-SYNC Converter that was announced in December last year, but with multiple simultaneous outputs and added USB support.
Funny that i already posted my idea for a module like this in late 2010 (Read that blogpost HERE)

A-190-8 Prototype 1

The main application of the module is the control of clocked A-100 modules like sequencers, sequencer controllers, trigger divider, trigger sequencer and similar units, but also to trigger/reset LFO's, envelope generators and more.

The A-190-8 will have 10 available outputs which are not yet fixed. 

Preliminary info can be found HERE, and if the users think other combinations of clocks or start/stop/reset outputs would be better, Doepfer can change that because the outputs are generated by the firmware of the processor.

Read some of the user suggestions at the Doepfer Yahoo Usergroup.

Doepfer left out the usual DIN SYNC socket because to create that you only need clock and start/stop on two pins of the DIN socket. 

If there are sufficient inquiries Doepfer may offer a special cable with two 3.5 jack plugs on one side and a DIN plug on the other. 

(For example to synchronize a TB-303)

A-180 Multiples and
a 2 HP blindplate,
the size of
the new A-180-2

For early in 2013 also a slim version of the A-180 Multiples module is planned.

This will be called A-180-2 and will be half the size of a regular A-180.

Because of the only 2 HP width nuts cannot be used to mount the pc board by means of the socket nuts at the front panel. 

Instead of that the PC board is mounted by screws and spacers at the front panel.(pic)

Personally i don't think i want one of those in my system because of how a nut-less module looks, but i can imagine there are people who applaud space-saving modules like this.

There were also a few other announcements/updates:
In December the A-192-2 (Dual CV/Gate-to-USB/Midi interface) will be available and even the hardware of the Polyphonic CV/Gate interface A-190-5 is ready.
"Christian (Assall) is about to program the firmware. But it takes longer than expected  and so the A-190-5 will be available early in 2013."

Special thanks to Bakis Sirros in the Doepfer Usergroup for sharing parts of this info.
Bakis can be found via multiple ways, support him and his band(s) to help the Greece economy a bit:

Doepfer Usergroup Poll: Voltage Controlled Slope Module

Recently Dieter Doepfer ordered a new poll in the Doepfer A-100 Usergroup.
It looks like he is seriously considering a 'Serge Voltage Controlled Slope' -inspired A-100 module.
If there is enough positive feedback it will be manufactured with the license of the copyright owners of the Serge module ( and it may also have the additions that Ken stone has designed).
Because of the license fee, the module's price will be a bit higher than standard A-100 modules.

Bananalogue Serge VCS PCB

In the early 1970s, Serge Tcherepnin developed the Positive Slew and Negative Slew modules for the original Serge synthesizer.
In time these merged into the classic Dual Universal Slope Generator.(Vimeo link with video)

For example;
The Serge VCS module, (re-)released in conjunction with bananalogue.com was/is an extremely versatile control voltage generator and audio source.
The Bananalogue VCS and CGS75 are both an adaptation of Serge's original circuit with a few new features.
At first glance it seems to be a VC slew limiter but after a closer look you can discover a very versatile module which can be used as a VC-LFO, VCO, AR-envelope, VCF, envelope follower, waveshaper, subharmonic and a trigger delay.

That's nine functions in one module!
It is not sure which functions the Doepfer module will have, but i guess they will try to get the most out of it.

So, the question in the Usergroup is:
" Would you buy a Doepfer A100 'Serge Voltage Controlled Slope' inspired module? "

The poll will remain open for one month, until 19th of December.
Voting is possible at http://launch.groups.yahoo.com/group/Doepfer_a100/surveys?id=13160415 (for Usergroup members)

For those interested in the theory of operation, I recommend Tim Stinchcombe's page on this subject.

Doepfer A-110-2 Low-Cost VCO Announced

A-110-2 Basic VCO

Always nice, those unexpected new module announcements.

Doepfer announced the A-110-2 on their site recently, a low cost VCO, similar to A-110, but sawtooth, triangle and rectangle with PWM only.
The module will have a 3-position octave switch (instead of the rotary switch of A-110), Soft and Hard Sync inputs, linear FM input.
This should all fit on a 8 HP front panel, the 'original' A-110 is 10 HP wide.

The module is planned for fall 2014 and will be priced at around Euro 110.00
(The A-110 costs 140 Euro's)

Power consumption:
- 150 mA +12V
- 150 mA -12V

- 50 mm Depth

Update Oktober 13, 2014: 
Dieter Doepfer in the A-100 Usergroup 
"...the A-110-2 is planned still for this year.
I hope the first units will be available end of November. 

The pcbs are already made. 

We are waiting only for the front panels."

Dark Energy II Specifications Announced

From the Doepfer website:

The Dark Energy (I) has to be discontinued because an important electronic part (CEM3394) is no longer available. (Read more on that HERE)
We are working on the redesign of the Dark Energy at full speed.
The new Dark Energy II will look like the Dark Energy I at first sight.
Only the function of some controls and switches will differ from the Dark Energy I.

from the band 87PM

These are the most important differences between Dark Energy I and II:

- 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)

All other functions will remain unchanged.
Even the price will be the same (currently Euro 428).
The Dark Energy II will be probably available summer 2012.

Doepfer hopes to have a (working?) prototype ready for the MusikMesse in Germany, which starts next week.

Dark Energy II Announced

Well, it looks like Dieter Doepfer announced the discontinuation of the Dark Energy today.

In the Doepfer Usergroup he stated that " the Dark Energy will be discontinued as the CEM3394 chip is no longer available and the negotiations with the manufacturer (OnChip, the Curtis Electromusic successor) concerning a new productions series of the CEM3394 were not successful so far. 

We think about a redesign of the unit (Dark Energy II) but it will be another instrument with a different sound and features (e.g. probably a 12 dB multimode filter with lowpass, highpass, bandpass and notch (like the A-121 Multimode Filter- (they will probably use parts of the DIY Synth circuit (e.g. the multimode VCF) for the Dark Energy II design) - instead of the 24 dB lowpass)."

Dark Energy picture provided by Marc Weerts
from the band 87PM

Logically this would mean that the A-111-5 Mini Synth Voice will also be discontinued since it has the same circuitry inside.

The Dark Energy did have a unique sound, mainly because of the linear filter FM.
There is no A-100 VCF available that offers this feature and even the VCO and VCA are unique.
The VCO is close to the A-111, but there is no A-100 VCA module available with the combined linear/exponential response of the Dark Energy/A-111-5 VCA.

Personally i do not think Dark Energy II will be the best name for a module like this and that they should go for another name instead, since it will be a completely different instrument with a unique character.
Feel free to leave some name-suggestions below or on the PatchPierre Facebook page.

Doepfer probably still has a bunch of Dark Energy's and A-111-5 modules left in stock*, but if you really want one you should get one before they are gone...

* Update:
From Dieter Doepfer in the Doepfer Usergroup:
" ...we miscalculated the relation of the Dark Energy / A-111-5 sales. The A-111-5 stock will last much longer than the Dark Energy stock. I expect that the Dark Energy will be sold out in 2-3 months, but I suppose that the A-111-5 stock will last one year or even longer."
Update II:
" ~ 4000 Dark Energy's were made, and ~ 300 A-111-5 modules "
