Teensy 3.6 as standalone mediator between USB MIDI and Eurorack

Sebastian writes: USB MIDI controllers (such as Launchpad Mini Mk II for example) are common and often quite low in cost. To interface such a controller with a Eurorack synth system, often a host computer and a MIDI to CV interface might be used. The host computer would take USB MIDI data from the MIDI […]

Traktorino, an open source DIY MIDI controller

Here’s an Arduino based open source MIDI controller by Musico Nerd, the Traktorino: The Traktorino is a powerful low-cost DIY MIDI Controller. It is based in the Arduino platform and it comes in DIY kit, or assembled. In its core, there’s a shield that connects to an Arduino Uno, which uses open-source code, making it […]

Building a Midi hat and jukebox using the Raspberry Pi

Dr. Scott M. Baker has published a new build: I picked up a Roland SC-55 to use with my retrocomputer setup recently, and I figured it would be cool to turn the thing into a standalone midi jukebox, so that no “computer” is required. I also figured this would be relatively easy, using a raspberry […]

Vintage MIDI: Roland MT-32, Roland SC-55, HardMPU, and an Xi 8088

Dr. Scott Baker writes: In this video, I decided to upgrade my home built PC from AdLib sound to MIDI. I tried out a couple different midi modules, the Roland MT-32 and the Roland SC-55. I learned that I’d need an MPU-401 or compatible ISA interface, and I explored the alternatives, eventually settling on the […]

Video: Talk MIDI with the Bus Pirate on Talk Like a Pirate Day

Here’s a video tutorial on how to set up the Bus Prate for the MIDI protocol from Bent-Tronics: Until now there hasn’t been much on the interwebs on how to set up the Dangerous Prototypes Bus Pirate for decoding MIDI data. Here’s my contribution, which happens to be on International Talk Like a Pirate Day. More […]

Make the world’s cheapest MIDI tester

Jesse from Bent-Tronics has posted a tutorial on how to make a DIY MIDI tester: A quick and dirty (and cheap) MIDI tester.  Sometimes you just need to know if a MIDI controller is outputting anything. Even many high-end MIDI modules/boxes will have a “MIDI Activity” light, just to let you know something is being transmitted/received. That’s […]

MIDI OUT for vintage Korg CX-3

Michael from AcidBourbon writes, “This project is about adding a MIDI output to a vintage organ, the Korg CX-3 (famous Hammond compact organ clone). My Korg was built in 1979, so before the introduction of the General Midi standard. But tapping into the right (only three) conducting paths on the main PCB and using a […]

Making MIDI hi-hat controller from unused bass drum pedal

Hwmayer documented his DIY MIDI hi-hat controller from unused bass drum pedal: Recently one of my friends bought an electronic drum set made by polish manufacturer “DIG DRUM”. The drum set is very good and combined with the Alesis triggerIO works really well. Unfortunately the pedal for controlling the hi-hat open/close signal was not included […]

Digitaly enhanced vintage music box

A digitally-enhanced vintage music box: “Digital Enhancement” is an interactive sound installation consisting of an electrified Symphonion Brevet No. 28, a synthesizer, an amplifier and four headphones. The Symphonion musical box dates back to the beginning of the last century and its mechanical workings are combined with digital technology to convert it into a MIDI […]

PreenFM open source FM sound module

According to its developer, French software engineer Xavier Hosxe, “PreenFM is a set of electronic components and C++ files that, when put together become a Frequency Modulation sound module.” It’s designed around a Leaflabs Maple Mini (available from Seeedstudio) and a collection of supporting components including EEPROMs, optocouplers, shift registers and op amps complemented by […]

Android Arduino MIDI sequencer

Here’s a project from SuLuLab using an Android smartphone to send commands via WiFi to an Arduino board in order to control a MIDI sequencer. It uses the new Processing 1.5 which provides Android support. SuLuLab writes: The first application developed to study the new Processing mode is a graphical interface for the simple MIDI […]

Arduino MIDI RGB display interface

Here’s a MIDI keyboard interface project from SuLuLab. It uses an Arduino, MIDI Shield, addressable RGB LED strip based on chip HL1606, 5VDC 1.5A PSU for strip supply (USB port current is not enough), and the Arduino’s FastSPI_LED library. MIDI messages from the keyboard (real or simulated on PC) enter the MIDI Shield’s MIDI IN […]
