Behringer Poly D 4-Voice Polyphonic Analog Synthesizer!
The Behringer POLY D lets you conjure up virtually any monophonic or polyphonic sound imaginable with incredible finesse and ease. The pure analog signal path is based on authentic VCO, VCF, VCA and ladder filter designs in conjunction with a dedicated and fully analog triangle/square wave LFO. Owning a POLY D is like having your own personal time machine!
Three modes to choose from
With the POLY D, you can get the best of three worlds by switching between monophonic, polyphonic or unison modes. With the POLY D set to Mono, you can have the characteristics of a classic monophonic synth with fuller, more expressive solos, bass lines and portamentos.
Flipping the switch to Poly allows you to play more than one note at the same time to produce stunning chord harmonies and luscious pads that add soul and depth to your music. Unison Mode thickens up your sound by layering all of the POLY D's voices on top of each other, adding more harmonic content and creating a richer sound.
The POLY D has four highly-flexible Voltage Controlled Oscillators (VCOs) that provide an incredible range of 5 waveforms for sculpting the perfect sound. Oscillators 1, 2 and 3 options include: triangular, triangular/saw, saw, square, wide pulse, and narrow pulse, while OSC 4 features: triangular, reverse saw, saw, square, wide pulse, and narrow pulse.
Additionally, all 4 VCOs can be adjusted across an extremely-wide, 6-octave range (LO, 32', 16', 8', 4' and 2').
24 dB Ladder Filter and VCA
The very heart of the POLY D's sound is its highly flexible 24 dB Ladder Filter. POLY 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.
