Often considered to be the opposite of filters within a modular system, wavefolders are designed to fold a signal over itself multiple times. This generates additional harmonics, resulting in rich timbres.
While there is a bewildering array of filter types within the synthesiser world, most wavefolders fall within only a few categories. Diode wavefolders in particular come in just two variants: series and parallel circuit topologies. Choosing a specific folder also means being limited to specific sounds and capabilities.
For the first time, Fold 6 puts forward a 6-stage hybrid series/parallel topology, yielding a greater sonic palette than ever in just 4 HP. Having both main (series) and alternate (parallel) outputs means a single module now gives access to just about all wavefolding tones imaginable.
To take things even further, an integrated symmetrical soft clipper limits the output signals to approximately 10 Vpp, keeping the amplitude within typical Eurorack levels and making it easier to create overdriven sounds at high fold ratios. This clipping stage can be driven continuously using the shape parameter, smoothly transforming the folded waveforms into pulse waves for even more harmonic content.
Two signal inputs are included, to mix audio signals or add in a DC voltage for asymmetric folding. The symmetry can also be manually controlled using the dedicated knob. Of course, both fold and shape parameters feature voltage control, to enable continuous timbral modulation.
Moving beyond simple signal processing, Fold 6 also lends itself perfectly for feedback patching, CV folding or frequency multiplication; its modest size belies the sonic capabilities within.

Poland orders:
- Standard shipping is free on orders over 250 PLN. Express shipping is free on orders over 500 PLN.
What about local taxes?
By default prices on the site include sales tax at 20%. The precise sales tax rate for your country will be calculated at checkout.
Do you ship to my country?
We ship to all EU member states from our warehouse in Warsaw, Poland. Add an item to your cart and enter your country and postcode to see the available shipping options and prices for your location. If you have any questions about shipping to your country, drop us an email at info@signalsounds.eu and we'll be happy to help.
Shipping methods
All EU orders are shipped via UPS. We offer two service levels:
- UPS Standard – our default shipping option. Delivery times vary by country (see estimated delivery times below).
- UPS Express Saver – next business day delivery to most EU destinations.
Each product page shows the estimated delivery time for your location, so you'll always know what to expect before you order.
Estimated delivery times (Standard shipping)
The times below are estimates in working days from dispatch, based on UPS Standard service. Express Saver delivers by the next business day to most destinations.

| Spain | 4 |
| Sweden | 3–5 |
These times are estimates and are not guaranteed. Delivery may occasionally take a little longer due to customs processing, local conditions, or carrier delays.
Dispatch times
Orders placed before 15:00 CET (Central European Time) on a working day are normally dispatched the same day. Orders placed after 15:00 CET, or on weekends and public holidays, will be dispatched on the next working day.
If you have an urgent order, please email us at info@signalsounds.eu before placing your order and we'll do our best to accommodate you.
Pre-orders
If a product is listed as a pre-order, it means we've ordered it from the supplier but it's not physically in stock yet. The product listing will include an estimated shipping date based on the best information we have from the supplier, but do bear in mind this is subject to change and is not a guaranteed date.
If you place an order containing a mixture of in-stock and pre-order items, we'll normally hold off on shipping anything until the pre-order item(s) have arrived, rather than splitting it into multiple shipments. If you need the in-stock items sooner, we'd recommend placing separate orders. As always, please get in touch at info@signalsounds.eu if you have questions.
