Infradeep's PVX-800 is a Siberian analogue synth based on the Polyvox circuit design

The Polivoks [Polyvox] was an 80s synth from the Eastern side of the iron curtain. After what Siberian company describe as "legal difficulties and formalities", their PVX-800 synth, which was inspired by the circuit design of the original, is ready to ship. The 325 × 135mm synth is available in both blue and white models. 

This duophonic synth kicks off its sounds with two oscillators, with a choice of five waveforms: sine, triangle, saw, square (with PWM) and 'shark', a triangle-style wave with a curved trailing edge that makes it look like a shark's fin.

Two ADSR envelopes and an LFO with eight waveshapes back up the soundsculpting potential, and there's also a built-in delay. Add this to USB and DIN MIDI input, and the PVX-800 can play nice with a wider setup. That LFO can even be synced to MIDI when in its square shape.

You can hear the sound of the PVX-800 in the charming (and delightfully cheesy) video demo below.
