Model-D style synthesizer with polyphony. The Behringer Poly D Polyphonic 4-Voice Analog Synthesizer builds on the success of the Behringer Model D incorporating a 37-note keyboard with the addition of polyphony. This 4-voice polyphonic analog synthesizer brings the powerful and analog warmth of the original with the added versatility of being able to play chords. The Poly D provides a faithful recreation of the original circuitry including four VCOs with a wide range of waveforms and controls. The top panel can be toggled to sit at various positions from flat to stood-up for optimal positioning. The classic 24dB ladder filter with VCA is also present as well as an LFO BBD stereo chorus and a flexible 32-step sequencer. Bringing the original into the modern era the Poly D also includes MIDI connectivity as well as USB and DIN. With 84 controls in total and a portable design the Poly D is the perfect choice for sound designers and musicians alike. A model synthesizer The Behringer Poly D is a Model-D style analog synthesizer with a 37-note keybed and a polyphonic mode. Staying true to the original the Poly D is a faithful recreation of the original. Behringer has payed close attention to the subtle details basing its design on the original circuitry complete with matches transistors and JFETs. Other premium-grade components include the high precision 0.1 percent thin film resistor and the polyphenylene sulphide capacitors. Birthed in the 1970s the original synth was revered by music artists around the world. Notable artists that used the original include Rick Wakeman Jan Hammer Keith Emerson and a whole host more. The original was a high-end synth with a hefty price tag but Behringer are committed to paying homage whilst retaining an affordable price tag. The original was renowned for its superior sound shaping and sculpting capabilities providing the means to create unique sounds and tones. The 37-note semi-weighted keybed provides velocity sensitivity allowing for optimal expressiveness when playing. The pure analog signal path combined with the wide range of controls and the polyphonic design makes the Poly D a must have for sound designers. Get in-depth with your sound creation The Poly D is jam-packed with controls and parameters designed to put in the driving seat when it comes to creating sounds and tones. The analog circuitry delivers that classic vintage warmth that is so sought after. The synthesizer boasts five variable oscillators shapes as well as variable pulse widths for flexible tonality. The classic 24dB ladder filter with resonance allows you to capture the essence of vintage sound creation. It provides multiple controls for the utmost flexibility including Cutoff Frequency Emphasis and Contour parameters. You can toggle between two modes for selecting the frequency range. The simple Lo/Hi pass settings provide a quick and easy way to interact with your sounds. Four ultra-flexible VCOs At the heart of the Poly D are four flexible Voltage Controlled Oscillators (VCOs) complete with five waveforms to choose from. The first three oscillator’s waveforms are comprised of: triangular/saw saw square wide pulse and narrow pulse. The fourth oscillator features triangular reverse saw saw square wide pulse and narrow pulse waveforms. You can adjust the oscillators using the ultra-wide six-octave range. The exceptional flexibility and ability to blend waveforms makes the Poly D perfect for creating new and unique sounds. Monophonic polyphonic and unison modes A trifecta of varying modes. The Poly D possess three separate synth modes comprised of: monophonic polyphonic and unison modes. When set to Mono the Poly D provides the playing capabilities of a classic monophonic synth. This is perfect for creating full-sounding solo bass lines and portamentos. Switching to Poly mode allows for added depth providing the ability to produce chords and stunning harmonies. Unison Mode provides the ability to thicken up your sound by layering all of the Poly D’s voices on top of one another. This creates more harmonic content resulting in a fuller and richer sound.
