Eurorack modular synthesizers have been growing in popularity over the last few years. Eurorack modular synths are relatively inexpensive, compared to larger formats, and pack a lot of functionality into a small space.

There are now over fifteen companies making Eurorack synth modules, giving Eurorack owners more options than just about any other modular synth platform. If you’re planning a Eurorack synth, there’s an online modular synth planner you should check out – the Mega Modular Planner.

Here’s a list of active Eurorack modular synthesizer manufacturers, along with links to recent coverage of their synths at Synthtopia:

The EuroRack Monster Planner is an online application that lets you make your plans to rule the world with synth power!

It’s the crack cocaine of synth fantasies, because you can use the Regular 12U Planner to design a relatively reserved modular synthesizer or you can choose the Monster Planner and plan your TyrannoSynth.

Bwa-ha-ha-ha!

There are some great examples of what you can do with the EuroRack Monster Planner at MusicOfSound.

And if you use the EuroRack modular planner to create an awesome modular synth of your own, put a link to it in the comments!

In the interview, Biddulph discusses why he got started making synth kits:

I first became interested in electronics when at High school back in England. I had just become aware of an electronics magazine called Practical Electronics when they published a design for the PE Sound Synthesiser. As that time I was also taking piano lessons and the synthesiser seemed the obvious hobby to incorporate both of my interests. With the aid of a friend I built the PE Synthesiser, the project was not only interesting because of the electronic/music combination but also because it was a complete stripboard design and proved to be a great introduction in how to prototype designs. 

An off-the-cuff visit to a record shop resulted in me coming across Walter Carlos. At that time I bought Switched-On-Bach and then my interest in electronic music was given a healthy boost. Jean Jarre and Mike Oldfield have been inspirations for me since then.

Some years later I was somewhat frustrated having bought a Christmas present for my son to find, on Christmas day, that not only did the unit require a power supply and/or a battery but it needed cables for connecting to a computer and came with software that did not work with the OS we had at the time. As my, then, job was with an e-Commerce company and I was involved with the main day-to-day duties of running the business, I saw the opportunity to offer a `full’ kit for the product that include all the `missing parts’ along with an improved manual and a series of projects notes. The unit was the `HotChip’ from Dick Smith Electronics, an ATMEL AT90S8535 based core module.

Shortly after offering this kit I came across the ASM-1 by Gene Stopp and saw an immediate problem (certainly here in Australia) in getting all the parts together to build the unit plus I realised that again there was a need to `complete the manual’. Conversations with Gene eventually resulted in me taking over the project and I started offering component kits for the ASM-1. Some design guides were created withe the ASM1-Genie being the first solution offered as a complete ASM-1.

When the stocks of ASM-1 boards ran out I took the opportunity to release the ASM-2 which included some additional modules to help make a more complete synth-on-a-board.

Having now started sourcing components for the ASM-1/ASM-2, it seemed an obvious step to see what else was being offered in a PCB-only option and I was pleasantly surprised to come across the Cat-Girl Synth from Ken Stone – a locally based person. When I first spoke it Ken it was with regards offering component and hardware kits for his designs as they stood on his website. These kits are still offered and, hopefully, I have helped some budding electronic-music enthusiasts to achieve their aspirations of building a synth with some exotic modules. 

Check out the full interview at the Vicmod site. 

Elby Designs has introduced a new line of Eurorack format synth modules, based on Ken Stone’s Catgirl synth designs.

The range will consist of completely re-designed PCB’s adapted for the smaller format of the EuroRack system. We will be offering both fully-assembled modules as well as Component and Hardware Kits.

In addition to the CGS modules we will also be including a number of other designs.

Panther modules will be offered in the following options:

• A fully assembled and tested module ready to plug directly in to your EuroRack system. Power supply connection is via a Doepfer A-100 compatible connection.
• A COMPLETE component kit. This includes the all board for the module, a Front Panel and all the components required to fully dress the board(s).
• The Front Panel. A high-quality 2mm aluminium panel with photo-etched black printing
• PCB Set. A full set of PCBs as required to construct the Panther module

Details at the Elby site.

The world of Eurorack modules is getting crowded!
