Used Behringer Model D Legendary Analog Synthesizer with 3 VCOs, Ladder Filters, LFO and Eurorack Format

VCO Triple Play
MODEL D's 3 highly-flexible Voltage Controlled Oscillators (VCOs) provide an incredible range of 5 waveforms for sculpting the perfect sound. Oscillators 1 and 2 options include: triangular; triangular/saw; saw; square; wide pulse; and narrow pulse, while OSC 3 features: triangular; reverse saw; saw; square; wide pulse; and narrow pulse. Additionally, all 3 VCOs can be adjusted across an extremely-wide, 6-octave range (LO, 32', 16', 8', 4' and 2'). This amazing flexibility gives you all the tools you need to be your creative best.

24 dB Ladder Filter and VCA
The very heart of MODEL D's sound is its highly-flexible 24 dB Ladder Filter, which lets you freely experiment with the Cutoff Frequency, Emphasis and Contour to dial in the perfect sound. MODEL D's Filter Mode switch can be set to either Lo- or Hi-pass for selecting the range of your choice. You can also adjust the Attack, Decay and Sustain controls to affect the cutoff frequency with time. The VCA Decay switch lets you set the length of time the note lingers after the key has been released. Additionally, support for filter-keytracking allows you to select how much filtering is applied based on the note being played. And if you want to add modulation, just set the Filter Modulation switch to the On position and use the Controllers Mod Mix knob to make it so. The VCA can even be overloaded via MODEL D's feedback circuit to add insane spice and edge to your sounds- without saying "goodbye" to your precious low-end content.

Making Waves
You are always in complete control of MODEL D's onboard modulators, which features: adjustable Tune; Mod Depth; LFO Rate; Glide (portamento); and Mod Mix knobs. A range of switches is provided for selecting between: triangle or square wave oscillation; modulation On or Off; OSC 3 or Filter EG (Filter Envelope); and Noise (Mod SRC) or LFO. The Tune knob is used to adjust the frequency of OSC 1, 2 and 3 (as long as the OSC 3 switch is turned off). The internal Noise generator, which is switchable between either Pink or White noise for dramatically expanded waveform generation, is the default modulation source, unless an external Mod Source is connected at the 3.5 mm input jack. As we stated earlier, the BEHRINGER MODEL D is the ultimate mono, all-analog synthesizer in its class - especially when it comes to sound quality, versatility and affordability.

16-Note Poly Chain Ready
While it is a monophonic instrument (one note at a time), MODEL D's 16-note Poly Chain function lets you combine multiple synthesizers for up to 16-voice polyphony - plus provides vastly improved reliability and stability over its 1970s and '80s predecessors.

Semi-Modular Design
Designed around an intuitively-linear workflow, MODEL D benefits greatly from its semi-modular design, which requires no patching for immediate performance. Just connect your favorite keyboard or computer via MIDI over DIN or USB - and start exploring the world of analog music synthesis right out-of-the-box.

Eurorack Ready
Designed to handle the rigors of life on the road or in the studio, your MODEL D can easily be transferred into a standard Eurorack case for the perfect integration into your existing system.

Controls & Connectivity
We just can't help ourselves - like you, we're gear-heads, too. For those who want the numbers, MODEL D has 29 knobs and 19 switches, all laid out in a highly-intuitive format that puts the joy back into your music creation. Input and output connections include: MIDI I/O and Thru over USB/MIDI DIN; modulation and audio inputs; OSC1 frequency control; external control of filter cutoff, resonance and contour; Main Out - and Phones, with its own dedicated Volume control.

Unleash Your Imagination
When it comes to not just pushing envelopes but creating them, MODEL D gives your imagination its voice - and it's so very affordable. When modern performance calls for classic analog sound - it calls for the BEHRINGER MODEL D!
