5U MFOS Synth Modules

With thanks to our friends at MFOS & Synthcube, these wonderful analog synth projects are once again available from the UK. For many years, Soundtronics supplied the PCBs, kits, panels and technical support to customers across Europe and beyond. Now trading as Sonic Synths, the PCBs are manufactured by us under licence to the original PCB designs.

Over time, we will add kits of parts, components and panels based on demand. If you can't find on our website what you need for your MFOS project, contact us and we will endeavour to assist.

Some projects may also be suitable for Eurorack applications largely depending on PCB size as the supply voltages are also +/-12V except for a few battery powered Lo-Fi noises boxes.

If you want to use these modules on +/-15V, check out the MFOS website for guidance, where possible, it may require component value changes.
