XIAO SAMD21, Arduino and MIDI – Part 5

This part looks at USB host device support on the SAMD21 based XIAO. This means that rather than plug the XIAO into something else, like a computer, instead other things, like USB MIDI keyboards and controllers, can be plugged into the XIAO. Unfortunately this wasn't as smooth and successful as other posts, but there still … Continue reading XIAO SAMD21, Arduino and MIDI – Part 5 →

Arduino and USB MIDI

I've been dabbling for a while with USB MIDI on an Arduino, but I've never really walked through all the options available or pulled together in a single place all the projects I have, so this post looks at all that in a bit more detail. Warning! I strongly recommend using old or second hand … Continue reading Arduino and USB MIDI →

Arduino Multi MIDI Merge

I've already had a basic MIDI merge project, combining USB MIDI and serial MIDI into a single serial MIDI out (see Arduino USB MIDI Merge). This project takes that forward to provide the options for a whole range of MIDI IN interfaces merging to a single MIDI OUT. In Part 2 I develop the code … Continue reading Arduino Multi MIDI Merge →

Arduino USB MIDI Merge

This project uses two off-the-shelf Arduino shields to provide a USB and Serial MIDI merge to a single Serial MIDI OUT. https://youtu.be/AB49UNDIrcM Warning! I strongly recommend using old or second hand equipment for your experiments. I am not responsible for any damage to expensive instruments! These are the key Arduino tutorials for the main concepts … Continue reading Arduino USB MIDI Merge →

SAMD51 USB MIDI Multi-Pot Mozzi Synthesis

When I left my Trinket USB MIDI Multi-Pot Mozzi Synthesis – Part 3 I had the following: Mozzi synthesis on the Trinket M0 board (that uses the SAMD21 Cortex M0+ processor core at 48MHz). Four note polyphony. USB device functionality - it can be controlled via MIDI over USB from a PC. USB host functionality - … Continue reading SAMD51 USB MIDI Multi-Pot Mozzi Synthesis →

USB-MIDI to MIDI Revisited

Ever since building my Mini USB-MIDI to MIDI I've wanted something a little more self contained. Most of these projects have been built with 8-bit microcontrollers, but the costs of more powerful microcontrollers is coming down all the time and you can now get very powerful 32-bit ARM based boards for really not very much so … Continue reading USB-MIDI to MIDI Revisited →

USBMIDI to MIDI Shield

I've been using my Korg Minikeys for testing a number of these projects, which usually means breaking out my Mini USB-MIDI to MIDI converter, but that means I need to find jumper wires, power, etc, so I thought it would be interesting to mount the appropriate components onto an Arduino pro-shield to create an entire "USB … Continue reading USBMIDI to MIDI Shield →

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 USB MIDI VS1053 Synth

This project builds on the Arduino MIDI VS1053 Synth but introduces a neat little module from Hobbytronics.co.uk that lets you use a range of USB MIDI controllers with the Arduino. Warning! I strongly recommend using an old or second hand keyboard for your MIDI experiments. I am not responsible for any damage to expensive instruments! These … Continue reading Arduino USB MIDI VS1053 Synth →
