The Viking's user interface

The Viking is a free software synthesizer available as a standalone application. It is portable, requiring no installation. On Windows, simply unzip the .zip file and run the executable inside; on Mac, just unzip and run the app.

The Viking uses additive synthesis to produce Dynamic Tonality tunings and timbres. Scale pitches result from successive additions and subtractions of a period (e.g., an octave) and a generator (e.g., a perfect fifth). The period and generator can be set to any size, making a wide variety of microtonal tunings easily accessible.

Version 2.0 was rebuilt from scratch for efficiency, cross-platform capability, and new functionality. It allowed full manual control of partial amplitudes, it also features a new morphing capability that allows you to create two different amplitude configurations, and morph between them using any combination of a slider, envelope, and LFO modulation.

Version 3.0 introduces a number of enhancements. These include: richer sounds achieved by doubling the number of partials in the additive oscillators; up to 9 simultaneous oscillators, which can be variably detuned to create deep chorusing; a large number of new temperaments (tuning systems and mappings between the sounds' partials and those tuning systems); improved reverb.


The Viking is a portable standalone application distributed in a zip file. The latest Windows and macOS versions (3.0.2) were uploaded on 20th April 2020.

Possible issues on macOS:

  • On first run, you may need to right-click (control-click) the app and select 'Open'.
