What is a prototype?

A prototype is a preliminary model of something. Projects that offer physical products need to show backers documentation of a working prototype. This gallery features photos, videos, and other visual documentation that will give backers a sense of what’s been accomplished so far and what’s left to do. Though the development process can vary for each project, these are the stages we typically see:

Proof of Concept

Explorations that test ideas and functionality.

Functional Prototype

Demonstrates the functionality of the final product, but looks different.

Appearance Prototype

Looks like the final product, but is not functional.

Design Prototype

Appearance and function match the final product, but is made with different manufacturing methods.

Production Prototype

Appearance, function, and manufacturing methods match the final product.

Our UNCPROP FamilyTool makes use of the genius DFAM, Mother-32, or any other semi-modular synthesizer and aims to make them even greater. The FamilyTool consists of a unique MULT-OR-SWITCH module and a powered 20hp black extruded aluminum case with wooden end cheeks – the UNCPROP case. The FamilyTool combo is exclusive to this Kickstarter campaign – it will not be sold as a unit afterwards!    

It will ship ready to play starting approximately July 2019. And here’s what it does:

 1. MULT-OR-SWITCH Module    

  • 6 A/B switches for up to six switchable routings
  • 2 of which are OR-logic mixers
  • No external power source needed*
  • Passive MULT (1:4 or 2x1:2)
  • Patching fun with 24 I/Os

2. powered UNCPROP Case

  • Fits eurorack modules up to 20hp and 35mm depth (e.g. Clouds and MATHS)
  • Perfectly fits DFAM/Mother-32 and
  • Is a great addition to any other semi-modular synth
  • For heavy users & beginners
  • internal PSU
  • works as a 20hp standalone eurorack case/effects unit
  • Handcrafted wooden panels (walnut)
Case and module are now also available separately – we have added these two new rewards to the campaign.
The MULT-OR-SWITCH module operates passively. To power other eurorack modules, we have implemented an internal PSU (Power Supply Unit) for all backers.

The FamilyTool will be assembled by hand in Munich, Germany.

We are Uncertain Proportions and now we’re building uncertain props – UNCPROPS. We’ve been building, modding and –most importantly– playing all sorts of synths for over ten years now. There’s a deep fascination for these delicate and monstrous machines that captured us right from the start. Besides jamming in our studio we compose music for performing arts, play live and host soldering workshops. Our professional background besides musical education includes communication design, architecture and conceptual design – with the FamilyTool we want to give a useful piece of gear to a community that has presented us with nothing but love and support from day one. We’re proud to be part of the modular world and hope you fancy our addition to it.

Millions of possibilities – new sounds. We want you to benefit from the eurorack system without the necessity to start a whole rack. Within minutes you’ll now be able to massively extend the functionality of two of the best synthesizers ever built (or really any other semi-modular synth).

The FamilyTool includes a 20hp extruded black anodized aluminium body to fit the eurorack standard. With its two wooden side panels the UNCPROP case attaches perfectly to your DFAM and Mother-32 synthesizers or stands boldly next to any other semi-modular synth, extending them in space and functionality.  With its built-in PSU you can power up to 3 eurorack modules within the 20hp space.

The lightweight UNCPROP case can be fixed with a couple of screws on either side or in-between two DFAM/Mother-32. The slightly adjusted shape of our UNCPROP case provides space for any eurorack module up to 35mm in depth.

The PSU is powered by the DFAM / Mother-32 internally or by a separate DC plug*

Live gig or jam session – now better than ever. Our FamilyTool module itself combines the best tools available for a passive prop.

The MULT-OR-SWITCH module offers:

  • 6 A/B switches including two OR-mixers
  • Passive MULT
  • Double, triple or quadruple your inputs - millionize your creative output
  • Attenuated switching between two sources to one dedicated out – or vice versa
  • Up to six switchable routings allow to prepare multiple patches at the same time
  • Switch modulation destinations and sound sources immediately - whenever wanted
  • Control the amount of your sources or mute them instantly

Two of the six A/B switches offer a passive OR-logic mixer that gives you control of the rectified sum of the A and B input – or just one of them. The new type of sounds you can come up with and the versatility you gain by switching between them give you more control – especially cool when playing live!

On the left side of the module you’ll find a passive MULT which allows you to multiply a signal four times or to duplicate two individual inputs.   

The intuitive and functional design provides instant access to all parameters quickly.

Welcome to the family!

Updated Rewards!

We're just getting started!

1) Side panel variety: Choose between different side panel options. Upon reaching a financing volume of EUR 32.000 (approx. USD 36.500) we will offer additional materials and finishes for the side panels for you to choose from. Any affected backer will be able to choose their favorite before shipping without any additional cost.

2) Cables: 6 patch cables (15cm) included when total backing reaches EUR 28.000 (approx. USD 32.000).

Please note: DFAM is a trademark of Moog Music Inc. We are neither affiliated with nor in any way endorsed by Moog Music Inc or any other shown manufacturer. We just love what they do and want to compliment them.

* DC plug not included.


International backers outside of the EU: Please be aware that you might have to pay customs fees when receiving your order form Germany. We will declare everything accurately in the shipping documentation.


Risks and challenges

A working prototype has already been built and works reliably. In a next step the design will be finalized and readied for production.

The most cost-intensive part of this venture is the aluminium body of the case which requires a set of expensive tools in order to be manufactured. Luckily, we already have a manufacturer in place.

The other components of the project are also planned and some of them secured. After this campaign ends, we will be able to negotiate the final contracts with our suppliers and set up a waterproof timeline for production and shipping.

Due to our previous experience and given the high level of preparation prior to this campaign, we are very confident to meet timelines for production and delivery.
