VK-1 Viking Synthesizer gives you the authentic classic analog synthesizer experience. It's a monophonic synth with three oscillators and a 4 pole ladder filter. Add to this plenty of modulation and control voltage capabilities and you get a timeless synth design.

All parameters in Viking have been modeled from real analog hardware, from the oscillator waveforms, to the filter, to the envelopes. Try it out. The proof is in the sound.

Product details


At the heart of Viking 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.


Most virtual analog synthesizers miss out on one of the most important aspects on analog synthesis, control voltage. Numerous individual CV inputs as well as CV inputs into the modulation busses means that everything in the synth can be controlled by 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. The drive can be adjusted to control the amount of distortion.


All of Viking's controls can be automated making it one of the most flexible synths in Reason.

Viking features state of the art analog modeling technology:

  • Viking's oscillators are free running, not sampled, wavetable based, or generated from a zero point
  • Viking's oscillators have instability, which is controllable through the tuning drift control
  • Viking's oscillators use advanced techniques to avoid aliasing
  • Viking's nonlinear filter uses circuit modeling and provides soft clipping

New in version 1.1.2:

  • Fixed LFO Rate modulation bug
