Arduino MIDI Interfaces

This are a mixture of beginner and advanced, DIY and off-the-shelf, options covering MIDI in (receive), MIDI out (send), and USBMIDI to MIDI conversion. All link into the RX and TX pins of your Arduino or other microcontroller. All are designed for 5V logic signals. Here are some other pages of interest: Ready-Made MIDI Modules … Continue reading Arduino MIDI Interfaces →

Arduino PWM MIDI Synthesis with Mozzi

This project uses an off the shelf synthesis library to create complex sounds using pulse-width-modulation (PWM) on one of the Arduino's output pins. For further Mozzi experiments, you can take a look at Arduino FM MIDI Synthesis with Mozzi. Warning! I strongly recommend using an old or second hand keyboard for your MIDI experiments. I am not … Continue reading Arduino PWM MIDI Synthesis with Mozzi →

Arduino MIDI Delay

As mentioned when I made my MIDI In-Out Half-Shield, there are some neat opportunities for MIDI related effects, so this is my MIDI delay implementation. https://youtu.be/rnUY4i4nMPE This is marked "beginner" from the point of view of "just download the code and use it", but if you want to dig into the code it is really in … Continue reading Arduino MIDI Delay →

MIDI In-Out Half-Shield

I have an idea for a project that only uses part of the Arduino's IO so that got me wondering if I could fit a full MIDI shield into half the space of a full shield. Its more of an idle curiosity really as shields will stack and as I've already shown MIDI circuitry can … Continue reading MIDI In-Out Half-Shield →

Arduino Multi MIDI Tone Module – Part 2

So, this is a stripboard version of the Arduino Multi MIDI Tone Module. Code and functionality is exactly the same, but I've built a "holder" for four Arduino Nano boards with common power, linked RX and TX, and built-in resistors for speakers. Warning! I strongly recommend using an old or second hand keyboard for your MIDI experiments. … Continue reading Arduino Multi MIDI Tone Module – Part 2 →

Arduino Multi MIDI Tone Module

Looking back at the Arduino MIDI Tone Module one of the key limitations was its inability to play more than one note at once. So why not string a few of them together to give you Arduino MIDI Tone polyphony! In Part 2 I commit this to stripboard. https://youtu.be/mGESRYY3CGc Warning! I strongly recommend using an old … Continue reading Arduino Multi MIDI Tone Module →

Mini USB-MIDI to MIDI

This is essentially a remake of my Simple USB-MIDI to MIDI but using a mini MIDI Host Shield and an Arduino Pro Mini, which I've not used before, with a home-made MIDI out interface to make a simple "all in one" unit. https://youtu.be/mHmNyse8uJ0 Warning! I strongly recommend using an old or second hand keyboard for your MIDI … Continue reading Mini USB-MIDI to MIDI →

Simple USB-MIDI to MIDI

Having experimented with the Hobbytronics USBMIDI device, I always wanted to see if it was possible to build my own using an Arduino. And it turns out to be a lot simpler than I expected, as least to use the USBMIDI keyboard for MIDI OUT to another device. Warning! I strongly recommend using an old or … Continue reading Simple USB-MIDI to MIDI →

Arduino MIDI Channel Monitor – Part 2

I liked the way my Arduino MIDI Channel Monitor turned out so much that I decided to tidy it up and commit it to stripboard after all and I'm pretty pleased with the results. https://youtu.be/mgPapCQgJ7g In the video you can see the LED for channel 10 lighting up when the drums are played and the LED … Continue reading Arduino MIDI Channel Monitor – Part 2 →

Arduino MIDI Channel Monitor

Whilst messing about with MIDI drums at one point it would have been really useful to be able to check which MIDI channels had messages, so I thought it would be useful to have a simple MIDI channel monitor. The idea is that you have 16 LEDs, one for each MIDI channel, and if any … Continue reading Arduino MIDI Channel Monitor →
