As well as Oscillator mode, Freak also features a Sidechain input mode for modulation via the input or an external signal, and the unique Radio mode, emulating the sound of an AM radio.
In Sidechain mode, the directly analysed modulation signal can be blended with the output of an envelope follower, for a highly shapeable response, with a band-pass filter on call for narrowing the modulation frequency range. It brings a useful dynamic control aspect to Freak, and also makes us wonder why the other two plugins weren’t similarly equipped, for modulation of saturation amount, sample rate, etc.
In Radio mode, two Demodulation circuit types emulate an envelope detector and a product detector, the latter being the more spectacularly ‘resonant’ of the two. The Carrier knob sets the demodulation carrier frequency (increase for higher fidelity), and ‘dialling in’ the radio is done using the Tuning knob, with interference increasing to either side of the centre point. The demod circuit band-pass filter is also adjustable, for balancing resonance and noise.
Radio mode is tricky to get a handle on, but the evocative retro and extraterrestrial ‘broadcast’ sounds it makes are absolutely awesome.
