A dramatic upgrade from 2015’s Graillon, version 2 sees the addition of real-time repitching to Auburn Sounds’ vocal frequency shifter. The Pitch-Tracking Mod section is still in place – mixing four pitch-tracking, fixed-ratio ring or frequency-modulated copies of the input signal for the creation of really weird ‘robot voice’ effects – but now sits alongside new Pitch-Shift and Correction sections.
The spectral pitchshifter enables up to 12 semitones of adjustment up or down, with the Preserve Formants knob doing a good job of maintaining the gender and characteristics of the source vocal – to an extent, of course. The Correction section is used to snap the pitch of the incoming signal to discrete note pitches of your choice by deactivating/activating the graphical keys. Clicking a key turns it red and ‘kills’ that pitch – the source signal repitches constantly to the nearest blue note. The Correction Amount knob increases the depth of the repitching, while Inertia, Smooth and Snap Range control the ‘stickiness‘ and speed of correction, and the width of influence for the enabled notes. The circular indicator on top of the waveform display very effectively visualises the remapping of pitch as it happens. The waveform display itself doesn’t serve any practical purpose, though.
As well as all that, Graillon 2 also includes a rather filthy bitcrusher. It’s comparatively viable for real-time use, too, thanks to the introduction of just 23ms of latency when used on a live input signal.
At its low asking price, Graillon 2 not only applies relatively natural-sounding pitch correction when used with care and consideration, but – more importantly, we’d say – serves as a quite brilliant creative effect, bringing pitch correction and shifting together with frequency modulation in an interesting way that we’ve not seen or heard before.
