Behringer Monopoly Synthesizer

Behringer MonoPoly — Four-Voice Analog Synthesizer

The Behringer MonoPoly is a four-voice analog synthesizer that recreates the cult 1981 Korg Mono/Poly architecture at a fraction of the original's price. Four independent VCOs feed a shared SSM2044-based 24 dB low-pass filter, producing fat basses, aggressive sync leads, and dense pads. Velocity-sensitive 37 full-size keys, pitch and mod wheels, and a flip-up angled panel keep programming tactile. This model is the right choice for players who want authentic four-oscillator analog behavior with modern studio connectivity.

Four VCOs, Paraphonic Modes, and SSM Filter Character

What sets this model apart from typical monophonic analogs is its four-oscillator engine and three assign modes: Unison, Poly, and Unison Share. Oscillator sync and cross-modulation open a wide range from subtle FM timbres to screaming sync leads. The SSM2044 low-pass filter — heard in the Korg Polysix and PPG Wave 2.2 — delivers the warm, fat low end that defines this synth's voice.

Sound Generation — Four Analog VCOs and Noise

Each VCO offers triangle, sawtooth, and pulse waveforms with PWM, an octave selector covering 16", 8", 4", and 2", plus fine tuning and per-oscillator volume. A dedicated noise generator mixes in independently for breath, percussion, or air.

• Oscillators: 4 analog VCOs — independent waveforms, octaves, and tuning per voice
• Waveforms per VCO: triangle, sawtooth, pulse, PWM — covers classic subtractive and FM territory
• Built-in noise generator for breath, percussion, and air

Filter and Envelopes — SSM2044 with Dual ADSR

The shared 24 dB low-pass filter offers adjustable resonance plus keyboard tracking. Two ADSR envelopes — one for VCF and one for VCA — shape filter sweep and amplitude contour independently. Trigger modes (Single/Multiple) and Auto Damp determine how envelopes re-trigger when new notes arrive.

• Filter: 24 dB/octave low-pass (SSM2044) — fat, resonant character with keyboard tracking
• Envelopes: 2 ADSR (VCF + VCA) — independent filter and amplitude shaping per note
• Paraphonic architecture — up to 4 notes share a single filter and VCA

Modulation, Arpeggiator, and I/O

Two LFOs (MG1 with four waveforms, MG2 triangle-only) drive PWM, filter cutoff, and pitch vibrato. The arpeggiator offers up/down patterns with octave range and latch mode, syncable via 6.3 mm jack. CV/Gate I/O, MIDI In/Out/Thru, USB-B, and a portamento foot-switch input round out the connectivity.

• LFOs: 2 (MG1: 4 waveforms, MG2: triangle) — modulate PWM, cutoff, and pitch
• Arpeggiator: up/down/up/down with octave range and latch — pattern-based sequencing on tap
• CV/Gate I/O, MIDI In/Out/Thru, USB-B, and a portamento foot-switch input for hybrid analog/digital rigs

Who Is the Behringer MonoPoly For

The synthesizer is the right choice for synthwave producers, electronic musicians, and sound designers who want four-oscillator analog character at an accessible price. Players coming from softsynths will appreciate the hands-on programming surface with 41 dedicated knobs and a flip-up panel. Live performers benefit from the 37-key velocity-sensitive action and the arpeggiator's latch mode for hands-free sequences. From thick Italo-disco basslines to aggressive sync leads, this instrument delivers vintage architecture without the vintage price tag.

Behringer — Affordable Studio Tools Since 1989

Founded in Germany by Uli Behringer, the company has built its reputation on capable music-making tools at accessible prices, beginning with the Studio Exciter F. The portfolio expanded through mixing consoles like the Eurodesk MX8000 and grew further with the acquisition of Midas, Klark Teknik, and TC Electronic. The MonoPoly continues that mission by reintroducing a sought-after 1980s four-oscillator design.
