Behringer Poly D Explained: Features, Types and Tips
A four-voice polyphonic analogue synth based on the Minimoog D — here's what makes it distinctive and how it works in practice.
The Behringer Poly D is a four-voice polyphonic analogue synthesiser that takes the classic Minimoog D circuit as its starting point and adds polyphony — something the original never had. The result is one of the most affordable ways to get genuine analogue Moog-derived sound in a polyphonic package.
The Circuit and Sound
At its core, the Behringer Poly D uses three oscillators per voice and a ladder-style lowpass filter derived from the classic Moog topology. The filter is the instrument's defining characteristic — a warm, saturating lowpass with the characteristic resonance peak that makes the Minimoog sound identifiable across decades of recordings. In polyphonic mode, this filter runs across all four voices simultaneously.
The oscillators cover a wide range and include waveform selection — sawtooth, triangle and pulse waveforms with pulse width control. Oscillator detune between voices is one of the main tools for creating the rich, wide chorused pad sounds the instrument is suited to.
Polyphony and Voice Modes
Four voices is limited by modern standards but enough for full chords. The Poly D offers multiple voice allocation modes: standard polyphony, unison (all four voices on one note for maximum thickness) and paraphonic operation. In paraphonic mode, all voices share the same filter and amplitude envelope — a distinctive, slightly unpredictable behaviour that creates its own character.
The Interface
The front panel layout follows Minimoog conventions closely — oscillator section on the left, filter and amplifier sections in the middle, with modulation routings on the right. Everything is directly accessible without menus. This makes the learning curve gentler for players familiar with Moog-style synthesis, though the dense control layout can feel overwhelming to newcomers.
The Effects Section
Built-in effects include chorus and a basic delay. The chorus is particularly useful — it thickens the sound and works well with the paraphonic voice mode for creating wide, shifting pad textures. The effects can be bypassed when a cleaner signal is needed.
Connectivity and Practical Use
Standard MIDI and USB MIDI connectivity make integration with a DAW or keyboard controller straightforward. CV/Gate inputs allow connection to modular and semi-modular systems — a useful feature for producers who work in the Eurorack ecosystem.
