Notify me when its in stockThe oscillators of a Minimoog have always been regarded as particularly assertive; Behringer has added a fourth, equivalent tone generator to the Poly D for the proven trio. Thanks to this addition, the oscillators can be played in pairs in duo mode and paraphonically in "Poly" mode. If only one sequencer track is used in the "Poly" mode, the so-called wave sequencing is generated by setting different oscillator waveforms. This sounding base is complemented by the noise generator, which produces white and pink noise and the external audio input. The level of the six signals can be adjusted in the mixer and then pass into the charismatic filter. This is a classic transistor cascade with 24 dB edge steepness and switchable as lowpass or highpass, which again extends the possible sound palette. With the help of the modulation mixer, FM is also possible for oscillators 1-3 and the filter through oscillator 4.
In addition to the glide controller, which is the main controller for all tone generators, the Poly D has the well-known modulation mixer, which even includes an LFO with square and triangle waveforms. In the oscillator and filter section modulations and tracking can be switched on. The two A/D/S envelopes are assigned to filter and VCA and have a common decay phase. The keyboard is capable of outputting CV and Gate as well as Aftertouch and Velocity as control voltages. The last two have their own attenuator each, so that any target can be controlled in a finely tuned way. Jack inputs on the rear panel allow additional control options for Mod Source, Oscillator, Filter and Loudness (VCA). Here it is useful to connect the aftertouch and/or velocity outputs to these inputs with a cable.
Behringer has given the Poly D two classic analog effects: The distortion can be adjusted over a wide range of settings, from warm-up to a hefty overdrive, and really gets going when the resonance in the filter is turned up. Pro tip: use a jack cable (6.3 mm mono on both sides) to connect one of the two main outputs or headphone output to the external audio input, and you'll be happy to hear strong feedback sounds as the resonance increases! The second effect is an analog chorus, which has two basic settings that can also be used together. This way you can create wafting retro sounds at the touch of a button!
The internal, polyphonic sequencer has space for 64 patterns, each of which can be up to 32 steps long; accents can also be programmed. An arpeggiator with the most common playback modes is available as an option to the sequencer. On the back, the notes generated by the keyboard, the internal sequencer and the arpeggiator are communicated with the outside world via USB, MIDI and CV/Gate.
