The Behringer Poly D is Designed for the musician, producer, or sound designer looking for that classic ladder-filter sound of the 70's. Featuring quad-voice polyphonic, four-oscillator powerhouse with a pure analog signal path, 37-note full-sized semi-weighted keyboard, and built-in distortion and chorus effects. The synthesizer utilizes matched transistors and JFETs, precision 0.1% thin-film resistors, and polyphenylene-sulfide capacitors, which allow for flexible sound-shaping capabilities resulting in super-fat basses and lead tones, mind-bending effects, and progressive organ sounds. The Poly D offers a wide range of playable modes including mono, unison, and poly.
The four VCOs offer a wide range of waveforms for sculpting sound. VCOs 1, 2, and 3 include triangular, sharktooth, saw, square, wide pulse, and narrow pulse, while VCO4 features triangle, reverse saw, saw, square, wide pulse, and narrow pulse. Additionally, all 4 VCOs can be adjusted across a wide, 6-octave range (LO, 32', 16', 8', 4', and 2'). At the heart of the Poly D beats the highly flexible 24 dB ladder-style filter with controls for filter cutoff, emphasis, and contour. The filter can be switched between high-pass and low-pass, while the dedicated envelope allows the filter to be shaped over time. What's more, the filter can be key-tracked for realistic recreations of acoustic instruments.
Other notable additions to the Poly D include an arpeggiator with 8 patterns, a 32-step sequencer with 64 memory locations, two types of analog chorus, and an analog distortion circuit to add spice and edge to your sounds. The rear panel provides stereo 1/4" main outputs, a 1/4" external input for processing, and a variety of 1/4" CV inputs and outputs to add additional control over the instrument. Route the velocity to the VCA or Filter for expressive playing or interface with other external analog CV gear for even more sound design potential. The Behringer Poly D includes a power adapter.
