Freq out

A souped-up emulation of AD’s Eurorack module of the same name, Freqshift adds or subtracts frequencies to/from the source signal in order to create spectral modulation and pseudo-pitching effects. The Shift knob lowers the signal by 1kHz when fully anticlockwise and raises it by 6kHz fully clockwise, but switching to bi-directional mode flips the right channel so that it shifts down as the left shifts up and vice versa – stereo fun aplenty. Routing the output back to the input with the Feedback knob results in all manner of mental internal modulations, while the LFO sweeps the shift up and down at anywhere from 0.010-1Hz – evidently, it’s meant for slow timbral shifts rather than fulltilt oscillation.

Freqshift is a wonderfully experimental effect, delivering a wealth of strange chorusing, thickening, repitching, filtering and FM-style noises. We do wish the LFO range extended beyond 1Hz, though.
