Behringer - Poly D
With its successful Minimoog clone "Model D", Behringer adds one more and upgrades it to a paraphonic "Poly D"! This is an analogue synthesizer with a velocity-sensitive 37-key keyboard. This synth has been extended with a fourth, similar oscillator, duo split and paraphonic play modes, sequencer and the analogue effects chorus and distortion. As with the original from the 70s, a nice feature is the angled control panel, so you can always easily find the best control position.
The oscillators of the Minimoog have always been regarded as particularly assertive; Behringer has added a fourth tone generator of equal value to the Poly D trio. Thanks to this extension, the oscillators can be played in pairs in Duo mode and paraphonically in Poly mode. If only one sequencer track is used in "Poly" mode, wave sequencing is generated when different oscillator waveforms are set. This powerful sound base is complemented by the noise generator, which generates white and pink noise, and the external audio input. The level of the six signals can be adjusted in the mixer and they then reach the charismatic filter. This is a classic transistor cascade with 24 dB edge steepness and can be switched between lowpass or highpass, further expanding the possible sound palette. With the help of the modulation mixer, FM is also possible for oscillators 1-3 and the filter for oscillator 4.
Modulation & Controller
In addition to the Glide controller, which is the primary controller for all tone generators, the Poly D also features the well-known Modulation Mixer, which even includes an LFO with rectangle 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 aftertouch and velocity as control voltages in addition to CV and Gate. The last two have their own attenuators, so that any target can be controlled in fine doses. Rear jack inputs allow additional control of mod source, oscillator, filter and loudness (VCA). Here it is possible to connect the aftertouch and/or velocity outputs to these inputs with a cable.
Behringer has given the Poly D two classic analogue effects: The distortion is widely adjustable and ranges from warming up to a hefty over drive and really gets going when the resonance is turned up in the filter. 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 enjoy the fierce feedback sounds as the resonance increases! The second effect is an analogue chorus that has two basic settings that can be shared. This allows you to create waving retro sounds at the touch of a button!
The internal, polyphonic sequencer offers space for 64 patterns, each of which can be up to 32 steps long; accents can also be programmed. An arpeggiator with the usual playback modes is available as an option for 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.
