Behringer DeepMind 6
Analog 6-voice polyphonic synthesizer
Our take on the Behringer DeepMind 6 by Crutchfield's Michael Sokolowski
Analog synth heaven!
I have to say that Behringer has knocked it out of the park with the DeepMind 6 – an innovative, easy-to-use, great-sounding, and great-feeling instrument priced well below similar products on the market. The Deep Mind is definitely a breakthrough 6-voice polyphonic synthesizer, selling for hundreds of dollars less than similarly featured instruments. Simply put, you can't find a full-size polysynth like this at anywhere near this price. Behringer pulls off this powerful value proposition by combining prodigious engineering chops with the vast resources of their parent company to produce a high-performance keyboard instrument at a budget-friendly price.
As a lifelong student of subtractive synthesis, I know that it takes a while to unlock the secret powers of any instrument. Usually, it takes some deeply thoughtful knob-twiddling and a nose dive into a thick owner's manual before any sort of beauty can issue forth from the machine. Not so with the DeepMind: I was awash in rich textures and sweetly pulsing rhythms within seconds of plugging it in.
Don't get me wrong; the synth will certainly reward diligent research and practice, but it's not a requirement to access some pretty cool sounds pretty quickly. For me, the preset programs aren't usable and I find myself needing to deconstruct and reconstruct them immediately. People who like brash and in-your-face sounds may well be happy with the factory patches; but I generally go for more velvety sounds that blend well with acoustic instruments. At any rate, the machine can go there quite readily; don't base your judgment on the Behringer's sounds by simply cycling through the presets. It's an analog synth, for goodness' sake; the experience is all about making new sounds.
And making new sounds is a joy with the DeepMind. The controls layout mirrors the analog signal path from left to right, for easy and intuitive operation. In the middle sits the beautiful and easy-to-read display that serves as your operational home base. Every action you take is graphically echoed back to you here, keeping you grounded and allowing you to check out your patch at a glance.
You'll find edit buttons below each control bank that take you straight to the parameters you want, rather than forcing you to navigate complex menu systems. Thanks to this simple editing mechanism, the logical layout of the hardware controls, and the brilliantly informative-yet-easy-to-grasp display, I was able to find great sounds easily right out of the box without having to consult the owner's manual.
Easy-to-use, powerful controls
Oh, and the sound sculpting possibilities! Behringer gives us:
- 7 selectable waveforms for supreme tonal variety;
- 3 envelope generators for controlling frequency, amplification, and modulation;
- a handy high-pass filter for getting the low-frequency gunk and boom out of our sounds, as needed;
- and a sophisticated modulation matrix with 19 sources and more than 130 destinations lets you route your own parameter change circuits – just like you can with a modular synthesizer.
And for those times when you need to bring out the frequencies near your low-pass cutoff point, Behringer includes resonance control – another helpful arrow for the synthesist's quiver.
Patterns and sequences
And as most analog synthheads can attest, generating arpeggiated patterns and building compositional sequences are great ways to make a machine's sounds come alive. There's nothing that gives me greater pleasure than using an analog synth as my “drum machine” when jamming on multiple keyboards. So I'm seriously loving the easy access that Behringer provides to the DeepMind's multi-pattern arpeggiator and a 32-step sequencer.
The knobs, buttons, and sliders are all solid and smooth to the touch, evoking real build quality – a sense that's reinforced by the beautiful wood panels on the sides and metal chassis construction. Again: amazing at this price.
As for the keyboard interface, I find it to be 37 keys of solid and expressive action – with the aftertouch feel being particularly delightful.
Top-of-the line onboard effects
For me, the toppings on this tasty synth sundae are the four digital effects engines you can run simultaneously. Most analog synths don't include effects, so I always use delay and reverb pedals in my rig. It's nice to not have to share an outboard processing chain with my other instruments (and I save on patch cords). Legendary Lexicon 480L and EMT Vintage Reverb settings let you dial in lovely reverb effects. Behringer also asked sister companies TC Electronic, Midas, and Klark Teknik to create over 33 effects algorithms specifically for the DeepMind. You'll get additional reverb options, as well as killer delays, chorusing, flanging, phasing, distortion, and many other adjustable effects.

Why Shop With Us?10 Reasons.
Overview: The Behringer DeepMind 6 is a true analog, 6-voice, polyphonic synthesizer, featuring 2 oscillators and 2 LFO's per voice, 3 envelope generators, an 8-channel modulation matrix, 32-step control sequencer, arpeggiator, and 4 simultaneous effects with over 30 algorithms to choose from. It contains a total of 1,024 Programs, or "patches", arranged in 8 banks of 128, all of which can be overwritten. Its 37 semi-weighted full-size keys feature velocity sensing and after-touch while the front panel's 26 sliders, 33 buttons, 3 rotary controls, 2 wheels, and a large backlit LCD provide ample control for unlimited sound creation.
Oscillators: At the core of the DeepMind 6's sound are its analog oscillators. The signal path for each waveform is also purely analog with the pitch being digitally controlled for tuning accuracy and stability. Each of the 6 voices has 2 oscillators, which can be used independently or together, and a global Noise source is available as well. Oscillator Sync and Pulse-Width Modulation (PWM) are available along with Unison mode which can stack up to 6 voices per note. The Oscillator section also includes a Unison Detune function that varies the de-tuning of the Unison voices, as well as an oscillator Drift parameter that randomly varies the tuning of the oscillators slightly, mimicking the oscillator drift of older analog synthesizers. This tends to add "warmth" and movement to the sound. The DeepMind 6 offers 10 different oscillator modes: Poly, Unison-2, -3, -4, -6, Mono, and Mono-2, -3, -4, -6.
- OSC1: Oscillator 1 can generate two different waveforms that can be combined or run independently - Sawtooth and Pulse. Pitch Modulation is available for both waveforms, while Pulse Width Modulation (PWM) is available for the Pulse wave.
- OSC2: This oscillator generates a Square wave and has controls for Pitch Offset, Level control, as well as Pitch and Tone control modulation.
- Noise: The Noise generator is completely analog and produces pink noise with a gentle roll-off of lower frequencies.
Filters: The DeepMind 6 includes both low-pass and high-pass filters. The low-pass analog filter has selectable 12 or 24 dB per octave slopes with Resonance (capable of self-oscillation) and includes dedicated controls for Envelope and LFO amounts as well as keyboard tracking. The high-pass filter has a 6 dB per octave slope and includes a Boost switch which applies a +12 dB boost to the signal path fattening up the bottom end.
Envelopes: Three envelopes are included on the DeepMind 6: VCA, VCF, and MOD, each with 4 stages (Attack, Decay, Sustain, and Release). The envelope section has dedicated sliders for each of the 4 stages (ADSR) along with selector buttons for each of the envelope types. A Curves button switches the operation of the ADSR faders from adjusting the envelope to adjusting the curve of each stage of the envelope, allowing linear, exponential and reverse exponential curves.
- VCA: Is used to adjust the level or volume of the note being played over time.
- VCF: Is used to adjust the cut-off frequency of the filter for each note over time.
- MOD: This envelope can be used to modulate any of the Mod Matrix destinations for each note being played over time.
LFOs: The DeepMind 6 offers 2 LFOs (Low Frequency Oscillators) per voice with a rate, or speed, that can extend into the audible range. LFOs are used to modulate other parameters for effects such as vibrato or tremolo. 7 waveform shapes are available: Sine, Triangle, Square, Ramp Up, Ramp Down, Sample and Hold, and Sample and Glide. Each of the LFOs features adjustable slew-rate, modulation delay, key sync, assignable clock sync (internal or external MIDI), envelope auto-triggering, as well as delay and fade-in. The LFOs are also Mod Matrix sources and can be applied to any of 130 destinations. A Phase Link option is available for the polyphonic LFOs, allowing them to operate in Unison (Mono), or link with an adjustable phase shift between voices. The LFOs can also track key pitch via the Modulation Matrix, enabling cross-modulation type effects. The LFOs rate can range from 0 to 255, or 0.041 Hz (24.1 sec) to 65.4 Hz (15.3 ms).
Modulation Matrix: One of the most powerful aspects of the DeepMind 6 is the Modulation Matrix. Modulation is the process of controlling one or more properties (destinations) of a signal using another signal (source), such as using an sine wave LFO to vary the Filter Cutoff frequency up and down as if you were moving the Cutoff slider manually. The DeepMind 6 Modulation Matrix has 8 channels or "busses", each of which can have one of 19 Modulation Sources controlling one of 130 possible Destinations. Three parameters are available for each channel: Source, Destination, and Depth (amount).
Control Sequencer: The Control Sequencer is a modulation source, in the same way an LFO or Envelope is, by allowing a pattern to be created which can be used to modulate other parameters. The Control Sequencer has a looping editor which allows you to adjust the values for each step. The modulation waveform that is produced can have positive or negative values and the sequence length can be up to 32 steps for a large range of creative possibilities. The Control Sequencer can be set to synchronize with the first note you strike or synced with the Master BPM clock (internal or external). Swing can be applied to the clock signal as well. Editing options for the Control Sequencer are as follows:
- Enable: Turns the Control Sequencer On/Off.
- Clock Divider: Allows you to divide the Master BPM in a number of ways. Divisions can range from 4 bars to 1/64 note resolution.
- Length: Adjusts the length, or number of steps, in the Control Sequence.
- Swing: Allows you to adjust the Swing or "groove" of the Control Sequence.
- Slew-Rate: The Slew-Rate is the rate at which the value changes from one step to another. With a high slew-rate you will get a sloped transition between steps while a rate of 0 will give you an instantaneous change from one step to another.
- Key/Loop: This controls how looping and key synchronization will
affect the Control Sequencer. Options are:
- Loop On: This option makes the Control Sequencer loop continuously and won't restart when keys are pressed.
- Key Sync On: Forces the Control Sequence to restart when a key is pressed, but will not loop.
- Key&Loop On: Makes the Control Sequence loop continuously and also forces a reset when keys are pressed.
Arpeggiator: The DeepMind 6 Arpeggiator allows you to play a pattern based on the individual keys being held and has 11 modes to choose from that determine the playing order of the notes. The Arpeggiator's looping pattern editor lets you adjust the velocity and gate values for each step and allows the pattern to be up to 32 steps long. The pattern editor comes with 32 Fixed Presets and 32 User Presets to store your own patterns. Swing can also be applied to the Arpeggiator. Parameters for the Arpeggiator are as follows:
- Key-Sync: On/Off. On makes the Arpeggiator start playing as soon as a key is pressed. Off will start the Arpeggiator playing using the Master BPM (internal or external) and Arp Clock as its timing source.
- Oct: This determines how many octaves the Arpeggiator will cover when playing. Range is 1 - 6.
- Mode: This allows you to select how the notes in a Pattern will be played back. The 11 options are: Up, Down, Up - Down, Up - Inv, Down - Inv, Up - Dn - Inv, Up - Alt, Down - Alt, Rand, Chord, and As Played.
- Hold: On/off. Determines if the Pattern will keep playing after the last key is let go.
- Clock Divider: Allows the Master BPM to be divided in different ways. Time signatures available are: 1/2, 3/8, 1/3, 1/4, 3/16, 1/6, 1/8, 3/32, 1/12, 1/16, 1/24, 1/32, and 1/48.
- Rate (BPM): Sets the tempo of the Pattern (when using internal clock). Range is from 20.0 to 275.0 BPM.
- Swing: Allows you to adjust the swing or "groove" of the Arpeggiator. Range is from 50% to 75%.
- Pattern: This option allows you to select one of the 64 Arpeggiator Patterns: Presets 0 - 32 and User 0 - 32 .
Chord/Poly Chords: Another feature of the DeepMind 6 that adds a lot of flexibility is the ability to program cords that can be played with a single key press. In Chord mode you can program a single cord, up to 6 notes, to be mapped across the entire keyboard and in Poly Chord mode, multiple chords can be mapped to any of the 37 keys. The DeepMind 6 has enough storage space for 36 six-note chords.
Keyboard: The DeepMind 6 keyboard has 37 full-sized velocity-sensitive keys, with aftertouch, that can have one of three different selectable velocity and aftertouch curves to match any playing style. Aftertouch can be assigned as a Source, in the Mod Matrix, allowing it to control any Destination parameter such as volume, pitch, color, etc.
Polyphonic Portamento: The DeepMind 6 features Polyphonic Portamento that lets you create smooth mono and polyphonic glissandos between notes played. The Portamento time, or "glide time", can range from 0 (instant note change) up to 255 (10 seconds of glide) and a Porta-Mode setting gives 14 different options allowing the Portamento function to operate in different ways. There's also a setting to balance the amount of Portamento between the two oscillators.
Effects: Behringer has included an Effects section with over 33 algorithms to choose from, many from world-renown manufacturers such as TC Electronics, Midas, and Klark Teknik. Each Program can have up to 4 simultaneous effect engines with options such as: Reverb, Delay, Chorus, Flanger, and Pitch-shifting, as well as processing functions like: Compressor, Enhancer, Multi-band distortion, and Noise gate. With the DeepMind 6's signal path being completely analog except for the Effects section, an Effects Bypass option is available to keep the signal analog all the way through. Effects editing options include:
- FX Slots: These are the 4 slots you can assign Effect modules into.
- FX Routing: This section offers 10 different routing options for the 4 Effect slots with selections including: Serial, Parallel, various combinations of Serial/Parallel, and Serial with Feedback.
