Modulation is the core concept of modular synthesis: parameters changing over time, adding movement and musical interest to what would otherwise be merely static sounds. Being able to control the amplitude of signals throughout a patch is therefore essential, and one can never have too many voltage controlled amplifiers (VCAs).
Designed as a fully-featured modulation hub for Eurorack synthesisers, Morph 4 takes the basic concept of the multi-VCA module to the next level.
Four linear amplitude modulators are controlled by a master ‘morph’ parameter. The response of each modulator to this parameter is completely variable, both manually and under voltage control, and can be overridden if desired. Each response is triangular, with the ‘position’ parameter setting the maximum point along the morph axis, while ‘span’ determines the width of the triangle’s base.
In addition to separate signal inputs and outputs, a variety of combined outputs is available as well: A+B, C+D, add (unity gain) and averaging mixes, and instantaneous minimum and maximum. Input normalisation makes it easy to send the same signal to multiple modulators, while output and modulator response LEDs provide essential visual feedback.
The combination of master control, fully flexible modulators and multiple combined outputs creates a module truly embodying the spirit of ‘patch programmable’ modular synthesis. Use Morph 4 as a voltage controlled mixer, dual crossfader, dual panner, interpolating scanner, interpolating distributor, quad VCA, quadraphonic controller, slope modifier, rectifier, complex waveshaper or something in between any of those—the choice is yours.

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.

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.
