Tired of virtual analog synthesizers with little pretend keyboards and no control voltage? VK-1 gives you the authentic classic analog synthesizer experience. Everything you would find in a rack mounted hardware synth is here, and realistic, in an actual rack. Every aspect of the synth was carefully modeled after real hardware. VK-1 is available as a Rack Extension that integrates seamlessly with Propellerhead Reason. Own Reason? VK-1 is available for free trial and purchase in the Propellerhead Shop.

At the heart of VK-1 are three adjustable wave oscillators. The continuously variable waveform knob gives the oscillators a unique sound that can’t be achieved with the fixed waveforms found in most synths. A noise oscillator provides three types of noise, one specifically modeled after classic hardware.

Two modulation busses and an LFO provide flexible modulation capabilities. Numerous CV inputs as well as CV inputs into the modulation busses means that everything in the synth can be controlled with CV from other devices in the rack.

The filter is a classic transistor ladder filter modeled meticulously. Two DSP varieties are available allowing for either reduced CPU load or soft clipping. The number of poles is adjustable for a wider range of filter sounds.

Compare VK-1 to the leading brand:
– VK-1’s oscillators are free running, not sampled, wavetable based, or generated from a zero point
– VK-1’s oscillators have instability, which is controllable through the tuning drift control
– VK-1’s oscillators use advanced techniques to avoid aliasing
– VK-1’s nonlinear filter uses circuit modeling and provides soft clipping

Compare VK-1 to hardware:
Can you tell the difference? In these sound examples a hardware synth plays a patch followed by VK-1 playing the same patch.

VK-1 has numerous CV ins and outs for external control and modulation.
