WRINKLER USER GUIDE
Getting Started
Installation
1. ⚠ WARNING! Always make sure your eurorack system is turned off before installing a
new module. To be on the safe side, pull the plug before you start!
2. The 10-pin connector should already be connected to the Wrinkler with the red stripe on
the power cable oriented towards the bottom, matching the white line and -12V marking.
3. Connect the free end of the power cable to the 16-pin Eurorack header on your power
supply system. The red stripe on the cable should match the white line (-12V marking)
on the bus board.
4. Attach the module to the rails of your case using the included screws.
5. Power on your Eurorack system. You can now start using the Wrinkler.
Introduction
The Wrinkler consists of a primary wavefolder circuit and a secondary “creaser”, both
controllable via knobs and CV. Generally wave folders only work with low harmonic content
such as sine or triangle waveforms but this one comes with circuitry that can fold and wrinkle
ANY waveform you feed into it, including square waves! An offset function adds some extra
sonic abilities to the mix. The Wrinkler got two outputs; one with the folded signal and one with
a “squarified” version of the folds. Perfect for creating harsh, metallic sounds.
❶ Audio In / Contents
Generally wave folders work best with low harmonic audio content such as sine or triangle and
will typically start folding the wave into itself, producing rich overtones. However, square and
pulse waves will not behave in the same way. Typically with a common wave folder you’d
experience no change to the sound or even no sound at all. The good news is that the Wrinkler
has a switch (Contents) with which you can activate a circuit that actually will bend anything,
even the squares! And the sound it can create from a regular square will probably surprise you.
❷ Fold
The Fold knob basically controls the number of folds you want to add to your waveform. When
turning this knob (from zero), the wave starts completely flat (and silent), then it gradually
begins bending the wave, adding more overtones for every new fold. In a way it acts like a filter
in reverse but instead of cutting away frequencies it adds harmonic content.
The folding can also be controlled with CV via the Fold Mod jack. The Mod Level attenuates the
incoming signal so you easily can tune the effect to your liking. Works great with an envelope
generator for example.
❸ Crease
Just like Fold, the Crease function adds harmonics to your waveform. Crease, however, has a
more subtle expression since it only operates on every second fold (from the bottom and up).
This is useful when you just want to add some extra timbral brightness to the sound. Crease
also produces extra pulses, see Pulses output below.
❹ Offset
The Offset knob determines where on the waveform the folding should take place. This has a
great impact on the sound character and can also be controlled via CV. In a way it resembles
PWM and it’s perfect to animate with an LFO to get a rich moving sound.
❺ Outputs - Pulses and Waves
There are two outputs on the Wrinkler: Pulses and Waves. Output amplitude for both jacks are
controlled with the Level and Dry Level knobs.
❻ Dry Level
When folding a waveform you add a lot of harmonic overtones to it. Unfortunately in the
process, the fundamental gets weaker and you will lose some of its original low end content.
With the DRY LEVEL knob, Wrinkler lets you blend the original waveform with the folded content,
preserving all the lower frequencies.
