From sweet sub-octaves to wicked multiplier madness, Tiptop Audio's Fold Processor packs a ton of 'tude in a 12HP Eurorack module. It's a classic diode-based harmonic generator that "folds" an input signal and multiplies it before subdividing it to create cool square-wave subharmonics. Sweetwater Eurorack addicts tend to hang on to the Fold Processor because it can do amazing things to even the simplest signal you feed it ? all by simply generating standard sine, triangle, sawtooth, and square waves.

Fold in simple waves for complex results





The Fold Processor takes up to two inputs. Step one, your signal hits the fold circuit, which lays on one of the basic waveforms ? sine, triangle, sawtooth, or square, and anything in between. What's awesome about this circuit is that you can control the fold waveform via CV, allowing you to craft continuously morphing tones. Sweetwater synth geeks particularly like the results of feeding this CV in sample and hold.

Inject your tone with bias point manipulation





Simply adjusting the bias point of your signal can have a dramatic effect on your tone. With the twist of a knob, the Tiptop Audio Fold Processor can take your sound from gentle and smooth to hairy and a bit rude. Add CV control, and you get a whole extra palette of sound manipulation. Any way you apply it, the Inject phase of the Fold Processor preps your sound for the glorious sub-harmonic stage to come.





4-stage subharmonics add richness and depth





Each of the four subharmonic stages of the Fold Processor affects the signal one octave apart. You can blend and mix these harmonic generators to develop everything from ultra-fat bass patches to epically glitchy effects. And if you dig square lead tones, then you'll love what this Eurorack module can do for your rig. Add to that a separate Subdivide output, and you can take this tone back to the rest of your synth for extra manipulation.
