WOK has announced the release of BFS-1, a virtual recreation of the Bode Frequency Shifter. The original unit was available as an expensive module for the Moog modular system.

Wok’s frequency shifter is not a pitch shifter, which changes frequencies by a multiplication. Instead it shifts all frequencies/harmonics by adding a fixed amount.  Unlike a ring modulator, the frequency shifter is capable of changing the signal by a low amount, e.g. 1 Hz, to obtain effects known as “Barberpole flanging”.

This plugin has some additional features like delays for each section, an LFO (all host synced), an envelope with MIDI trigger and an envelope follower to modulate shift and/or volume.

BFS-1 is available now, as a Windows VST, for 33 EUR.
