Music Thing - Chord Organ

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 black 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.

Music Thing - Mikrophonie

This kit contains all parts to build the module, right down to the power cable and the screws. These kits ship with a white knob (not black as shown in some older photos). Internal contact mic is included. External contact mic must be built or purchased separately (see below).

 

Tom Whitwell the designer of Mikrophonie describes the module thus: “Mikrophonie is a microphone preamp with a piezo contact mic built into the panel. It is an easy way to bring environmental noise and feedback into a modular system, inspired by the early days of electroacoustic music in Paris and Cologne, and by the contact microphone and phonograph cartridge experiments of John Cage, Gordon Mumma, Robert Ashley and Nicholas Collins. Here is a wonderful film from 1966 of Stockhausen & Co performing Mikrophonie 1. The panel is PCB with no soldermask. The raw PCB fibreglass has quite a nice rough texture – rubbing it with a finger or a plectrum creates quite a wide range of sounds. The back of the panel is plated and grounded for shielding; the peizo microphone can either be soldered directly to the copper or stuck on with epoxy glue.”

 

The module will work with both DIYed contact mics made from inexpensive piezo transducers or the more professional and fully shielded Exploding Shed contact microphone.

Music Thing - Magnetophon

This is a full kit to build the module. It comes with two tapeheads, so you have an extra tape head to DIY a ‘wand’ as shown in this video. The Tapehead mounted into the module itself is of limited use compared to a wand. With a mono cassette head in the panel and a NAB equalised amplifier circuit, Magnetophon is a cassette player without the transport mechanism. Try rubbing old cassette tapes on the panel, or attach a head on a wire to recreate Nam June Paik’s Random Access or Laurie Anderson’s Tape-Bow Violin.

Music Thing - Startup

Startup is a headphone amp, six-input mixer, tap tempo clock, divider & multiplier in 4hp. It's the perfect way to start a small Eurorack case. Full DIY Kit.

Startup is designed to be the best way to start a small Eurorack case, featuring a Mixer, Clock & Headphone Amp. This is a really easy project for DIY newcomers, all the SMD components come pre-soldered and the PCB is programmed and testing prior to shipping. You just need to solder the buttons, jacks and pot. The Music Thing Modular ‘Startup’ is designed to be the best way to help start a small Eurorack case.

 

This 4HP module does three things:

1) It’s a 5 channel output mixer, with a spare channel for stereo signals (like a Korg Volca or a phone).

2) It’s a nice clean headphone amp with two outputs.

3) It’s a useful tap-tempo clock, with a second channel giving divided or multiplied clocks.

The best way to understand Startup is with with the Quick Start Manual.

 

This thing is super! See more backgound info and details on the Music Thing Website here. There are 2 instagram videos by Tom Whitwell here and here.

  • Current draw: 40mA
  • Width: 4 HP, Depth: 25mm

Music Thing - Spring Reverb mk2

This is a full kit that includes everything you need to build a 6hp Eurorack module, except the spring tank or digital brick. The Music Thing Spring Reverb Mkii is a flexible, easy-to-build voltage controlled DIY mono spring reverb module. Traditional guitar reverbs are tuned to the sound of the guitar and the amplifier it is played through. This circuit is different; designed to be relatively clean and high-fi, with a lot of bass response. Use real spring reverb tanks, or solid state reverb bricks.

 

New Features of the Spring Reverb mk2 include:

-Internal Feedback control with CV input, dedicated attenuverter and with invert switch for maximum feedbackiness

-Wet out and feedback in sockets for more flexible patching

-3HP Expander – allows for instant switching between reverb brick and spring tank – or set a blend between the two

-Expander also allows for front panel send and return to spring tank. You can get it from Thonk.

-New improved circuit

 

More Features

-Works with a variety of spring reverb tanks (optional), or with the Accutronics BTDR-2 reverb ‘brick’ designed by Brian Neunaber (optional)

-Vactrol (VTL5C3) crossfade between dry and wet (vactrol circuits are variable in their ability to go completely 100% wet, like the Make Noise Echophon for example)

-Tilt EQ on the reverb send to tune the voice of the reverb

-X-Fade input so the module can also be used as a standalone vactrol crossfader (crossfade demo)

-Feedback circuit with positive and negative phase

-Attenuverter on the crossfade CV input

-6hp wide (NB: If using the brick, mounted horizontally, the brick extends 5mm over the PCB to the left of the module, around 25mm back from the front panel, so mount the reverb next to a shallow module)

-Expander with Front panel mount Phono sockets & Crossfade between reverb types.

 

More background infos can be found on the Music Thing website. Here is a DivKid Video about it and here is a build video by Markus Fuller.

 

We provide genuine Accutronics/Belton Spring Reverb Tanks separately. They produce high quality and springy responses! All reverb tanks include 1M RCA cable.

Medium – 8EB2C1B  Springs: 3, Delay Type: Medium, Tank Dimensions: 23.5 x 8.5 x 3.3cm, Input Impedance: 800 Ohms, Output Impedance: 2575 Ohms, Mounting: Horizontal Open Side Down, Connectors: Input Insulated – Output Grounded

Large – 9EB2C1B Springs: 3, Delay Type: Medium, Tank Dimensions: 42.5 x 12 x 3.3cm, Input Impedance: 800 Ohms, Output Impedance: 2575 Ohms, Mounting: Horizontal Open Side Down,

Connectors: Input Insulated – Output Grounded

Instead of the reverb tanks you can use a digital brick, which you can find at Banzai Music.

Music Thing - Simple EQ

This full kit is great for learning SMD/Surface mount soldering. Build a super skiff friendly and great sounding EQ module. Music Thing have produced a new revision of this MTM board which includes a few through hole parts such as the electro caps to make this an easy way into surface mount soldering. It’s really not a hard kit if you’ve done a handful of through hole soldering projects previously. It includes a full and in-depth build doc for complete SMD beginners too. All parts are individually bagged and labelled and we’ve included extra parts for practice. More background infos can be found on the Music Thing website.

 

Simple EQ – Learn SMD soldering by building two channels of the kind of tone controls you’d find on an old hifi. No voltage control, but just enough range to push sounds into distortion. Works well in a feedback loop.

  • Current draw: 20mA @+/-12V
  • Width: 4 HP, Depth: 25mm

Building instructions can be found here. DIY level: easy/medium. SMD soldering is not recommended for complete beginners! Make sure your soldering iron has a good fine tip before attempting this build. A flux pen is also recommended.

Music Thing - Turing Machine mk2

Random Looping Sequencer

This kit includes everything you need to build the Mkii version of the Turing Machine. You just need to provide the tools and solder. Comes with 10 HP Aluminium Eurorack panel. Since it was launched in June 2012, the Turing Machine has become one of the most popular Eurorack DIY projects. It is a random looping sequencer that spits out basslines and melodies. It generates strings of random voltages that can be locked into looping sequences. These sequences can be allowed to slip, changing gradually over time. This module was inspired by the long history of shift register pseudorandom synth circuits, including the Triadex Muse, Buchla 266 Source of Uncertainly and Grant Richter’s Noisering.

 

The 2016 revised Turing Machine has many improvements:

-Rotary loop length switch

-Pulse out

-Two boards, includes Backpack circuit to drive expanders (compatible with old Music Thing expanders)

-Easier to build: a larger PCB in the same width, clock and noise circuits are more robust

-Noise level trimmer & reduced voltage in noise circuit to make circuit more robust with different noise transistors

-Compatible with existing expanders (Pulses, Voltages, Vactrol Mix) but not the BYTES expander.

 

Background infos can be found on the Music Thing website. Here's a DivKid video about it. Technical support and info via Github.

  • Current draw: 40mA @+12V
  • Width: 10 HP, Depth: 33mm
