A few examples outside of normal folding, just to get your imagination going.
Big mid-side PWM sound
Connect a sine audio signal to IN.
Set OffN and OffP in the center position. This sets both offsets to 0V.
Connect two different LFOs to P and N set to sine wave.
Adjust the P and N knobs clockwise till the FoP and FoN LEDs barely stops flashing.
This is the way to get as wide PWM as possible out from FoP and FoN.
Connect the FoP output to to the right in your mixer and FoN to the left.
Left in the OUT jack you now have the folded signal without FoP and FoN. Put the signal from OUT in the
middle of the mix.
You now have a mid side wide sound with two completely independent PWM signals on the left and right.
Letting two different ADSR control the VCA for the mid and sides of the mix is nice too.
Audiorate on top of ADSR
Envelope in on IN. Connect OUT to the frequency CV input to a VCF. Run some audio through the VCF.
Set OffP close to the top of the envelope. You can now fold down the top of the envelope with Mod.
Connect an LFO to P and set the amount of modulation that will be applied on the top of the envelope with
the P knob.
Connect the FoP out to resonance of the VCF. You can now set the level of resonance during the time that
the positive folder is active or not active with the FoP knob depending on which way you turn it.
Connect an LFO or audio rate signal to Lim or Dist via the E-1 expander. It will affect the OUT connected to
frequency on the VCF and could produce a bubbling or metallic sound from the filter depending on settings.
The negative folder is not yet used. You could set it up so FoN is adding stepped offset to the OUT signal.
Or even an other LFO in to N.
Pulsating audiorate modulation
Connect a sine audio signal to IN and set the OffP to 3 oclock.
Connect a slow sine from an LFO in to P and set the P knob to full clockwise.
Connect an audio rate signal to N and set the N knob to 3 oclock.
Set the Sym switch on.
You now have a sound that is the original sine wave in and at the rate of the LFO the audiorate modulation
comes down and cuts in to the sine wave. A pulsating sound.
The reason for the pulsating sound is that the LFO and the audio signal on P and N are added together when
the Sym switch is on, and the LFO carries the modulating audio and offset threshold in and out of range of
the folder.
Compressor - brick wall limiter - folder
You can side chain control where the compressor knee is via P and N.
Setting the Sym switch on will give a symmetrical compression, with Sym off you can set it asymmetrically.

With Mod set from off to middle position the WF-1 can act as
a compressor. On the picture you can see how the
amplification of the triangle wave decreases after a set value
at OffP and OffN.
Mod at middle position it will act like a hard brick wall limiter.
Mod above middle position will put it in to folding.
When used as a compressor you should know that there is
no makeup gain in the module. That has to be done with a
VCA after the WF-1.
