All user reviews for the Doepfer Dark Energy

A small simple monophonic synthesizer 100% analog: a fixed oscillator waveform (possibly a sub oscillator triangle or sawtooth) with PWM control, a low-pass filter 24dB resonant, VCA, ADSR Two LFO.

Opportunities for internal patch: LFO1 on the pitch, LFO2 the PWM and the cutoff of the filter ADSR on the PWM, the Cutoff and the VCA.
Opportunities (although very limited) external patch with control voltage (CV-5V to +5 V) output LFO1 opposite phase, output envelope, exit gate, 4 CV output (pitch, pitch bend, velocity and a final assignable that are related to the MIDI input), and some CV inputs: VCO pitch, VCO PWM, VCF cutoff, VCA amplitude and Gate.

The ranks of the VCO is large enough, it "understands" the MIDI signals on four octaves and you can change the frequency domain +1 / 0/-1 octave. There is a little more than an octave between the center position and the extrema of the knob.

For the cutoff, you can go depths recluses very low frequency (to the point of not having signal at all) to completely bypass the filter.
Resonance go far enough (self-resonance and even a little further with this kind of effect "ring modulator" a little trashy but not unpleasant). The filter is equipped with a loudness (bass boost) but it is pretty useless.

The LFO and ADSR have three time periods: short, medium and long. For long, it is possible to push the ADSR to something like 1'30'' Attack / decline / release for LFO can get around a few tens of hertz or below. In short, we can have an LFO in the field of audible (useful for mods that will ring very high) and the ADSR can get a very percussive sound (at least the knobs are a click, though) .

Finally level connections: MIDI in (no thru), USB, CV and food (a bit unusual by the way: AC 12V ...). There are also a lot of connections inside the box: a midi thru (in the form of a couple of pins, the cable comes with the unit), various jumpers to change options or to facilitate assembly several units, and a receptacle for a potentiometer glide (portamento) my time useful.


UTILIZATION

You can find some interesting sounds "fiddling" a little, but it is growing when you know what you are doing.

I personally received the manual in German ... hum ...

The big advantage of analog is that everything is 100% live and perfectly continuous (no effect "level" to the filter, for example).
The disadvantage is that you can not save presets. Everything must be done by hand editing to the recording paper (I did at first, but I do not think it's frankly useful).

A small disadvantage of the unit is that you forget the controls "end". For example, the button that controls the frequency modulation is very sensitive (get a slight vibrato is very difficult, it quickly falls into the large modulation). The same goes for using CV: pitch bend you made a tenth places one or two semitones down ...
The velocity is almost unusable as what ...
BUT all this can be corrected with external modules in Doepfer (attenuators for example).

SOUNDS

As I said above, it adapts to all styles and all feature (bass / lead / fx / pad). It can range from a soft to the trash always keeping the warmth of analog.
With a few (a delay, a distortion, for example) effect units can push trèèèèèèèès stuff away.
And for music lovers a little free, not even need a keyboard. You push the module auto mode and tamper buttons live for very diverse and interesting atmospheres.

OVERALL OPINION

I use it for a year, he never leaves me. I tried a lot of synthesizers, analog or not, and for its size, it has little in the stomach. Alone, he is not doing badly, but with a little company (effects, additional modules, other units!) It becomes a war machine.

What I like most is the range of sounds as varied and the ease with which one passes from one sound to another.

A small drawback, however, it is quite difficult to incorporate into the mix (you have to look a little to succeed in enhancing the use of a compressor is highly recommended).

The value for money is .... difficult to judge. There is really no other analog mono synths of this size.

I just regret not having bought the Mark II is equipped with a 12dB multimode filter that looks to me very attractive (it was not left at the time). I remake (s) this choice blindfolded without hesitation.

Semi-modular analog synth monophonic. No effect.

UTILIZATION

Standard configuration and effective. Manuel useless. Editing sounds spontaneous. Recreational use.

SOUNDS

This machine SONNE. It is effective in the register of bass, percussion, and lead, and I have not tried the pads ...

OVERALL OPINION

I have this machine for a few days and I'm about to c **. This is my first real analog and say waaah. I used a lot of vsti and more recently a Blofeld and there I fell in love. Usage is fun, the machine is robust, the sound is terrible. I find the filter a bit special. For 350 euros I would do certaiement choice.

Good for the features I'm not going to see prior reviews. But in a nutshell:
All there!

UTILIZATION

The use of such instruments requires a little knowledge in subtractive synthesis. At the same time it is very educational and requires from you a little imagination, curiosity and patience. For here is all done by hand, so bye bye preset, memories and other programs of assistance. Back to the roots!
Manuel hyper but clear English (on site) or German (paper) that allows only hand made quickly and without headaches.

SOUNDS

The sound is very binary at the same time this enough to play DE in the courtyard of the self-sounding instruments varied and constantly evolving.
We can get this little box a lot of bass sounds, leads, fx or string (mono) are very good bills. No need to get a compressor or a tube amp, the issuing his departure a clear, powerful and alive.
The sound resembles a bit of a Moog, I said a little and a little through the modulating LFO you find yourself out of it very retro atmosphere.
Or there is fun to grind, patch, adjust the various inputs and outputs of the module. Excellent! Within 15 minutes we can engage in editing sound surprising and completely barred.
Well it is best to get its signal in a delay / reverb, it makes the sound more enjoyable and less 'raw casting'.

OVERALL OPINION

Bought 2 years ago and sold for a trifle foolishly I bought recently and I do not regret it. The newer models seems more results in terms of filtering, unless it is my ears (which is possible). Although it is hardly bigger than a cigar box, the little Doepfer not be ashamed of its size or its possibilities. So for less than € 400 you are the owner of a fascinating instrument, scalable (modular), powerful and super easy to use. Must!

a nice little monophonic analog synth, convenient to carry, solid, although a fairly complete second oscillator and the ability to change waveform would have been welcome ... C

UTILIZATION

semi modular analog synth, so if you have understood the principle of subtractive synthesis is super simple ...

SOUNDS

Sonnne it well, after I passed through a Metasonix TM5 or a big muff and bass, then, it really rips, I use it for big bass a little saturated and disgusting ...
to nearly everyone to do his sound.

OVERALL OPINION

I use it for more than six months it has really integrated into my live ... I'll buy a slim phatty but I keep it anyway.
It sounds good, it is preparation and not expensive, I recommend it to anyone who wants to go to analog synthesis, thanks to the USB port, the VSTI farewell and welcome to the magical world of hardware ...

Monophonic analog synthesizer that delivers a rather low typed / leads. Autonomous, semi-modular architecture enables both internal routing the connection to other machines via the CV input. It includes a MIDI In connector, a USB interface and a wide range of outputs CV 3.5 mm.

Features
- 1 VCO (+ FM & Pulse Width Modulation & PW)
- 1 VCF, 1 envelope (ADSR) 2 LFOs
- CV Out: LFO1, Envelope + 4 CV out
- Resumes In: VCO, VCA, VCF, Audio In, Gate

UTILIZATION

Easy Setup
In my memory, but there is no manual on the site Doepfer a pdf with the following settings to reproduce the sound you want to have.

Editing sounds is easy once you understand how to market a modular synth. It may take a little time if it was not used to this kind of gear. Pdf helped me a lot.

SOUNDS

Is exactly what I was looking for.
One sound, modifiable at will, a powerful filter, buttons not cheap.
In addition it has a really wild look with its wooden sides and buttons everywhere. It's not plastic!
Ok it must not have big fingers, but we made it very well.
The knobs respond well, it's very well built case.

OVERALL OPINION

I use it for 1 year

In two weeks, I bought several machines before landing on this one:
An MFB: too cheap, its a bit short, return to sender
A Dave Smith Mopho: powerful but I'm not a fan of the preset. It's too clean to me, a good plug-in does the same thing. Not quite random. Resold in stride.

And there, for less than 400 € you have a mini minimoog.
Good value for money. I would do without this choice problem. I'm having!
If you like the presets and preset sounds, go your way.
It is a single sound, and you have to play around with before finding what one seeks.
It is a true modular, it will not interest everyone ...
I coupled with a filter moog MF 101: pushing the drive of moog, it sends the timber.

Okay now for 400 € + 250 for the filter, I would buy a moog Slim Phatty but was not released at that time. I'm having
