Affordable analogue sound module with many features

With 12 analogue voices, a modulation matrix, 32-step sequencer, and four high-quality FX engines, the Behringer DeepMind 12D polyphonic synthesizer has features that neither existed in the great era of analogue synthesizers nor are easy to find today - and all that at an unbeatable price. The DeepMind 12D module delivers massive soundscapes, rhythmically modulated sequences and arpeggios, and concise lead sounds. Besides this, it can be integrated into a studio or live setup - ideal to save space if no additional keyboard is required. With its analogue signal path, it delivers that popular, warm sound character while the four FX engines with algorithms from TC Electronic and Klark Teknik are a useful extension, especially for live use and to avoid having to use additional equipment.

Polyphonic analogue synthesizer with FX engines

The sound of the DeepMind 12D is generated via two oscillators, a 12/24dB low-pass filter, and a VCA in the analogue signal path. Oscillator 1 produces saw and square/PWM, while oscillator 2 produces square/pulse with a special Tone parameter. For modulation, each voice has three ADSR envelopes, as well as two LFOs with seven waveforms, including "sample & hold", which can also be synced to MIDI clock. A total of 19 modulation sources can be assigned to more than 130 different destinations via the integrated matrix, which leaves a lot of scope for sonic experimentation. Since sounds are usually mixed with effects, onboard FXs are standard these days. The DeepMind 12D even has four effect units, usable in parallel, with more than 30 algorithms with which the sounds of the synthesizer can be enhanced. These include reverb, chorus, phaser, delay, and many more.

Compact module for live and studio use

Anyone who already owns a high-quality keyboard, simply needs a more compact keyboard, or maybe even no keyboard at all, can get the DeepMind 12D as a desktop synthesizer or screw it into a 19" rack. Compared to the keyboard version, you don't have to make any compromises in terms of operation, as the module has the same selection of controls and buttons as well as a display. And when controlled by a hardware sequencer or a DAW, all of the important parameters can be changed intuitively while playing. The easy accessibility via the user interface facilitates the creation of your own sound designs. And if you want even more precision, the parameters organised in menus can alternatively be controlled via an app (iOS/PC/Mac) or by using an additional MIDI controller. In this way, the sounds can then be automated via a DAW.

About Behringer

The company, which was founded in Germany by Uli Behringer and now manufactures its products in China, has been known for affordable and great-value equipment since its very first product, the Studio Exciter F. An array of mixing consoles (such as the Eurodesk MX8000), signal processors, and later sound amplification and monitoring equipment, has made it possible for countless musicians to fit out their home studios, practice rooms, and mobile PAs within budget limits that were previously unthinkable. The acquisition of other companies, including Midas, Klark Teknik, and TC Electronic, meant that new product groups were added - and also resulted in the technical expertise of these companies being incorporated into product development.

Pads and other poly sounds

12 voices in one device still have a very high value in the analogue world today. Much more common are polyphonic analogue synthesisers with eight, six, or even just four voices. The DeepMind 12D can thus be used for "big" chords and polyphonic pads as well as for sounds with a long release without the voices being cut off too quickly. With two oscillators and one low-pass filter per voice, the sound structure of the DeepMind series is based on the great analogue classics from the 70s and 80s. The structure has proven itself in countless applications from a wide variety of genres. The end result is that you can quickly become familiar with it, plus you can work on your sounds in a targeted manner.

In the spotlight: DCO (Digital Controlled Oscillator)

As with some synthesizers from the 1980s (e.g. the Roland Juno and JX series), the oscillators of the DeepMind 12D are designed as DCOs. By mistake, these are often classified as “digital”. In fact, these are actually analogue oscillators that are only digitally controlled and are indispensable in a polyphonic synthesizer and for achieving reliable tuning stability. This technique prevents the well-known analogue drift in pitch, which occurs mainly due to temperature fluctuations over a longer period of use. However, the actual generation of the waveforms is fundamentally analogue.

Great value for money
adolfgottmann 05.12.2018
I bought it as a sort of polyphonic synth workhorse but after spending some quality time with it I must say it's way more than that!
Ok, It excels at vintage Roland-esque tones, but it would be an error to consider it as a one-trick pony or a generic-sounding device.
The highlights of course are the extensive modulation matrix and the included effects (internally modulatable). But envelope inversion e the possibility of setting curve per envelope stage are just wonderful!
The UI is well laid, and there is a bit of menu diving, but nothing too cumbersome.
As often noted, It's a bit limited in the oscillator department (the waveform choice is really really limited) but it doesn't seem a real problem to me, whit the effects and the massive modulation capabilities.
I have to add that it doesn't feel cheap at all, It's well build and I like the form factor (I have the desktop version).
I plan to use it in the studio, so I can't really comment on using it on stage.
The only shotcoming is, in my opinion, the filter resonance. It get nasty very quicky, hard to tame when you are past 70% of the fadr range.
All in al it's a nice device, capable of a wide range of tones, a real treat for sound designers. There are better polysynths, of course, but not at this price point. Kudos to Uli Behringer and the Midas team!


Deep Love!

I was very sceptic at first buying this synth, although there were quite a few reviews praising it. The reason was the oscillator waveform choices, with only one sawtooth oscillator and no sinewave. However I had a change of heart, since on one hand I loved the sound of Juno 106 (from which this synth took inspiration), and on the other hand I saw a reviewer who mentioned that the effects were a crucial part in the sound design capabilities of the DM. So I went ahead and bought the 12D version.

I have to say that I'm SO IN LOVE with it. Indeed: the effects plus the mod matrix are crucial features for its sound design capabilities. I would strongly advice to go for 12 voices, so that you can use 2-3 of them in unison for each note without significant polyphony loss (6 and 4 voices respectively). The filters sound great without being extraordinary, and the envelopes are quite steep and snappy.

On the downside, my main concern is the data entry knob which is plastic and a bit fiddly. Also the companion application does not work well with touch on windows and no android version is available.

Nevertheless this is definitely a keeper :)


Really good synthesizer for the price!!!
Giacinto32 08.07.2020
I bought this synthesizer from Thomann and ofcourse a part of the professionality of Thomann and the quick delivery the synthesizer is incredible! Really "Deep" as the name says and the synthesis capability of this synthesizer are almoust endless! You can pretty do what you want with the 2 OSC (that by the way sounds amazing) and the Mod system and the faders are a joy to use! It screams creativity and it lets you want create sounds!
Setting it up is really simple and I love that it comes with the 19" rack ears (if you are a rack guy and want to mount it on the rack. The screws for the mounting of the rack ears are in the box with the manual. So they have thought of everything when they made this synthesizer. The desktop size is perfect and the wood finish on the side are really nice! The noise from the fan in the synthesizer is really quite compare to other synths with fans on, so there you don`t need to worry about! To summit all, I am really happy of this purchase and I reccomend this synths!!


Definite depth
Evaluator 07.05.2019
A lot of onboard presets, but it's definitly build to build your own. The effects are very effective, I do prefer to ad a subtle amount so it won't lose the feel of the analog.
It has a tender, gentle vibe, which lends itself very well to build dreamy pads and such. It's very cheap, and almost entirely in a good way. The controller knobs feel a bit, well, cheap... And it lacks someting to keep dust from getting in through the slider gaps. But maybe they're better left open because of the fan, sucking in air (blowing it out). The fan has not bin an issue for me at all though, but it is noticable when you don't play it, on standard setting.
I bought it, and I kept it, so I think it's safe to say that I would recommend the Deepmind, when a subtractive polysynth with a lot of depth is what you are looking for, when you're on a budget.
