The Tiptop Audio Fold Processor Eurorack module is a sound processing powerhouse, capable of producing beautifully animated folding sounds from standard sine, triangle, sawtooth, and square waves. The module works by folding the incoming waveforms, adding odd harmonics and generating four more sounds spaced one octave apart through its subdivide generator. The versatility of the module stems from its voltage-controlled Inject feature that alters the bias point, creating a vast range of soundscapes.
One of the standout features of the Fold Processor module is its ease of use. The CV input comes with an attenuator that makes it incredibly simple to create complex, animated folding sounds. The module's flexibility is further enhanced by its adjustable voltage-controlled Inject feature, which introduces a different texture to each waveform, giving rise to a wide palette of sounds.
The subdivide generator is responsible for creating the additional four sounds, spaced one octave apart. Each generated waveform has its own gain knob, which can be mixed into the Subdivide output jack, resulting in anything from discordant square wave swarms to sweet harmonic oscillator stacks. The mixing of the four generated waveforms can produce a stable square version of the folded wave or freaky PLL-like glitched slides.
Overall, the Tiptop Audio Fold Processor Eurorack module is an instrument that allows you to create beautifully animated sounds with ease. It is a true multi-faced devil, delivering both sweet and evil sounds, and its versatility is perfect for anyone who loves exploring the full potential of sound processing.
Example Usage
To create a simple folding sound with the Tiptop Audio Fold Processor, start by patching an oscillator into the "In" jack and then patching the "Subdivide" output into an amplifier or VCA. Adjust the "Gain" knob for each sub-octave sound until you find a pleasing blend. Finally, use the "Inject" knob to adjust the bias point of the folded waveform to taste. Experiment with different waveforms and CV inputs for even more interesting results!
An intermediate-level usage example would be to use the Tiptop Audio Fold Processor Eurorack module to add some texture and depth to a simple melody. You can take a basic sawtooth wave from your oscillator and run it through the fold processor. Then use the CV input with an attenuator to create a sweeping animation. Next, try using the adjustable voltage-controlled Inject to change the bias point to create different variations of the sound. Finally, use the subdivide generator to add some sub-octave frequencies and gain knob to mix them. You can experiment and create new interesting sounds by adjusting the controls and CV.
Further Thoughts
One creative usage of the Tiptop Audio Fold Processor Eurorack module is to take a simple sine wave and pass it through the wave folder with a slow-moving CV input. Then, connect the folded signal output to the subdivide generator, which will square the wave creating four new sounds spaced one octave apart. Using the output mixer, adjust the gain of each channel to create a complex and evolving sound. Finally, connect the Subdivide output to a delay or reverb effect to add even more depth to the sound. This technique can result in beautifully animated folding sounds that are perfect for ambient and experimental music.
