WF-1 & E-1 Bundle

New SOLD OUT WF-1 & E-1 Bundle


DPW Design WF-1 & E-1 Bundle - Wavefolder and Expander


WF-1 is a Eurorack format wavefolder with some extra functions. It can used for audio signal manipulation or as a utility module for control voltages.


It has an IN signal that can be affected by the two control voltages P and N. The main output volume is controlled by the orange OUT knob.


The lines of the front panel are not just decoration. The are there to help understand the function of the module.


White lines show the clean signal path from IN that can be blended in to the main mix out on OUT. The level of clean signal is set on Clean.


Yellow lines show the modulation signal path. P is the folding of the positive side o the IN signal and N is the folding of the negative side.


Both sides have the same controls.


OffP is the offset signal, or threshold where the positive folding starts. Turned fully clockwise it will be above +5v and not affect an audio signal on the input. In the middle position it will start folding from 0v. Turning it further anticlockwise will make the positive folding start on the negative side, can be set all the way down to -5v.


OffN has the same function but is of course polarity switched compared to OffP. This means that turning both OffP and OffN max clockwise there will be no folding.


Knob P and N are attenuverters for adding CV control on top of the offsets OffP and OffN. Green / red LEDs show what are being added by the attenuverters.


The over all control of the amount of modulation is controlled by Mod. A green / red LED after the Mod control is showing the total combined modulation from the P and N side.


The switch Sym can chance asymerical to symerical modulation. That is when Sym on all modulation on P will be copied over to N and vice versa. In Sym mode OffN is disconnected, it would otherwise be in conflict with OffP.


FoP and FoN are logical signals that goes high when folder P respective N is active. Indicated by green / red LEDs. These signals are +/- 5v so they can be used as audio signals. This is not a clean square wave, it has been shaped to sound better.


The red knobs FoP and FoN are attenuverters. The output from them are normalised to the main mix OUT. This means that you could add or subtract square waves tat coincides with the folding.


With all the folding and adding of signals the output can easily end up with more the +/- 5v so a limiter / distortion switch is added to limit the maximum volume out and to add some extra sonic possibilities. This affects the signal going out to the SUM output.


The function of the Lim/0/Dist switch is:


Middle position 0, bypassed. The output volume control has a range of 0 to 1 times amplification.


Lim position, a soft stepped limiter that adds a lot of harmonics. Not made to be transparent. The volume control has a range of 0 to 5 times amplification to be able to drive signals harder in to the limiter.


Dist position, almost Fuzz type of distortion, frequency dependent. The highs are rolled off a bit. The volume control has a range of 0 to 20 times amplification so it can be driven really hard in to the distortion.


Both the limiter and distortion are DC coupled and of course works with control signals.


When something is connected to FoP or FoN that signal is disconnected from the main mix at SUM. This makes it possible to patch the three outputs from the module in many creative ways. As an example OUT can be a mono signal and FoP an FoN be treated as a stereo out for very big sounds.


The Wavefolder Expander E-1 allows you to CV control on and off of the Lim and Dist functions. One way to use this is as two types of CV controlled accent to the main output of the WF-1. You can actually turn it on and off at up to about 1.5 kHz speed giving a sort of frequency modulation effect.
