Music Thing Modular - Chord Organ
Product information "Music Thing Modular - Chord Organ"
Chord Organ is the easiest way to get chords from a modular synth!
• It's perfectly possible to create chords on a modular synth, but its a pain - lots of tuning and messing about. I wanted to create something as simple as a home organ with chord buttons. Chord Organ is exactly that; the top knob chooses a chord shape, the bottom a root note.
• The full story of Chord Organ, including how it was inspired by a Bontempi Organ found in the street, is in this article over on Medium.
• Chord Organ and Radio Music are identical modules; you can convert one to the other by installing new firmware over USB - details on how to install the firmware - and go back just as easily.
• This video shows what you can do with a Chord Organ in a simple little case. Here the chord shape and root note are sequenced by an expanded Turing Machine and filtered through a God's Box Humpback Filter.
• The top knob chooses the chord shape (Major, Minor, Drop 3 9th). The bottom knob chooses the root note. Both can be CV controlled.
• The latest firmware now includes:
• A choice of 12 waveforms (the original just had four) Program chords by uploading MIDI files Easy to use configuration page. Alternative tuning support by dropping standard Scala files onto the SD card (installation details).
• There’s a long history of press-button-to-get-chord instruments; accordions, the Suzuki Omnichord, the Autoharp, or all those auto-accompaniment electronic keyboards that you used to see.
Basically Chord Organ is a new firmware for the Music Thing Modular Radio Music module. It gives the module a completely different function. Instead of playing samples from the SD card, it synthesises chords. This is the full Chord Organ kit with dedicated Chord Organ silver Alu panel and button.
Note: you need to purchase a MicroSD card and a Micro-B USB Cable elsewhere to set up this module. The Micro-B cables are the smallest type shipped with Kindles and many Android phones. You also need a card reader to write files to the SD card, many laptops and desktops already have them built in now. The very cheap $2 MicroSD cards are not worth the trouble they will cause you, buy genuine SanDisk or Kingston branded MicroSD cards from Amazon or elsewhere. 32Gb maximum… that’s 108 hours of lossless audio in 16bit 44.1khz. Total file limit per card is 1200 files.
Features:
For the build guide the process is identical to Radio Music, you just program with a different hex file – http://github.com/TomWhitwell/RadioMusic
Chord organ now tracks 1v/Oct if you use the latest software downloaded here! – http://polyfather.com/chord_organ/
Details on how to load firmware onto the module can be found under the Software header here – https://github.com/TomWhitwell/RadioMusic/wiki/Preparing-the-Teensy
DIY-Kit-Type:
THT-Kit-1. This is a Do-It-Yourself kit, not an assembled module. The kit includes all parts to build the module. Only trough-hole parts to solder. Make sure to check the build guide before you buy. For build guide, more info, videos etc. please check the buttons below.

Product Safety Information
Eurorack DIY Kits
Important Notice & Intended Use
Please read this safety guide before installation or use. This kit is intended for adult users experienced in electronics and modular synthesis. Assembly, including soldering, is required. Proper testing and installation are essential to ensure safe and functional operation. The completed module is intended for installation in a Eurorack-compatible synthesizer system powered by ±12V and +5V.
General Warnings
1. Electrical Hazards:
• Ensure the power supply matches the module’s specified voltage and current ratings (refer to the product manual). Incorrect voltage can damage the module and pose a safety risk.
• Never connect or disconnect the module while the Eurorack system is powered on.
• Wrong polarity can damage your module or system. Make sure the module is connected with correct polarity.
2. Heat Generation:
• The module may generate heat during operation. Ensure proper ventilation within your Eurorack case to prevent overheating.
3. Sharp Edges:
• The module’s faceplate and components may have sharp edges. Handle with care to avoid cuts or scratches.
4. Small Parts:
• Contains small parts that could cause a choking hazard. Keep away from children and pets.
5. Compatibility:
• This module is designed specifically for Eurorack-compatible systems. Connecting it to non-compatible systems may result in damage or malfunction.
Assembly Requirements
• Soldering skills are required to complete the module.
• Ensure a clean, well-lit and ventilated workspace free of flammable materials during assembly.
• Use appropriate tools and safety equipment, such as eye protection.
Testing
• Test the module thoroughly for shorts or incorrect assembly before powering it in your Eurorack system. When the unit has malfunctions due to incorrect assembly, the entire Eurorack system might be damaged. It's a good idea to test it in a separate case with only that single module.
• Use a multimeter or other appropriate tools to confirm proper functionality.
Installation and Use
• Mount securely in a Eurorack case using the provided screws.
• Use only the included or manufacturer-recommended power cable.
• Connect only when the power is off.
• Follow the module's user guide for instructions on operation. Do not exceed the input/output limits specified.
Responsibility
Users are solely responsible for proper assembly and testing. Contact manufacturer support for assistance if needed.
Environmental Safety
• Dispose of the module, its components, and packaging in accordance with local electronic waste regulations.
Liability Disclaimer
• The manufacturer or distributor is not responsible for any injury, damage, or malfunction resulting from improper installation, use, or modification of this product.

Manufacturer "Music Thing Modular"
Eurorack Modular Synth format. They are designed in Herne Hill, London by Tom Whitwell.
I’m a former journalist and magazine editor (Mixmag & The Face). In the noughties I ran the Music Thing blog, before working at The Times. Got into DIY electronics after attending a workshop with Tom Bugs, reading Handmade Electronic Music, playing with Arduino and building guitar pedals.
Contacting me directly is rarely a quick way to get help with a project or a technical problem. GitHub issue lists are a good place to start (Turing Machine, Radio Music), a search of MW DIY will often find answers, as will looking at the Facebook Synth DIY group.
