Music Thing Modular - Radio Music

Product information "Music Thing Modular - Radio Music"
1) Radio Music is a virtual radio module, so it behaves a bit like a radio. It is designed to be a source of unexpected audio, not a drum loop player or a sample mangler. That said, plenty of people enjoyed it for playing drum loops or mangling samples.
2) Radio Music has been a popular DIY project since 2014, and has been used by Chris Carter, Russell Haswell, Richard Devine, and Robin Rimbaud.
3) In 2017, the module's firmware was completely rewritten and updated, bringing new features including pitch shifting, .wav file support and a new way to configure settings on the module. You can download the latest firmware here, which will run on any Radio Music module.
4) On the same site you can configure your Radio Music, changing various internal settings.
5) It's a well documented project, with a lengthy Radio Music Wiki and an active issues list for people seeking help with a build.
6) The wiki also contains a huge suggested audio bank containing lots of interesting things.
7) Like a radio, the module works on a series of banks and stations. Each of the 16 banks can contain many different stations. Each station is an audio file stored in a folder on the SD card. Choose a bank by pressing and holding the RESET switch. Choose a station by turning the STATION knob or plugging a voltage into Station.
8) Because the audio streams from the SD card, it can handle long files easily. In the default setting, it switches between long recordings just as if they were radio stations — as if the audio was playing in the background.
9) Radio Music runs on a Teensy 3.1 (or 3.2) microcontroller, which is programmed by USB and runs a very well documented Arduino-like language, so it's easy to hack.
10) There are multiple alternative firmwares for Radio Music documented in the github, and on Voltage Control Lab including:
- Chord Organ is just an alternative firmware for Radio Music, but is also available as a separate module. You can turn a RM into a CO (or vice versa) at any time using a normal Micro USB cable.
- Telharfauxnium is an additive synthesis firmware.
- James Carruthers has written several different firmwares, including a cool 808 drum machine
- I often use this Loop Divider firmware to sync everything to loops in a small case.

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.

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.
