Toy Keyboard USB Matrix Decode with the Pi Pico

I never really got back to looking at my "Toy Keyboard" - I wanted to do the same as the Vintage Phone - create a USB MIDI version with Circuitpython. Well now I have. Here is the result. https://youtu.be/VNmp3-mwysI Warning! I strongly recommend using old or second hand equipment for your experiments. I am not … Continue reading Toy Keyboard USB Matrix Decode with the Pi Pico →

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 →

Vintage Phone USB MIDI Controller

This is the USB MIDI controller version of the Vintage Phone MIDI Controller. As the USB MIDI support is much easier in CircuitPython than MicroPython, this is also a version of the keypad controller code for CircuitPython too. Warning! I strongly recommend using old or second hand equipment for your experiments. I am not responsible for … Continue reading Vintage Phone USB MIDI Controller →

DIY MIDI Interfaces

This page is a mixture of beginner and advanced, DIY options covering MIDI in (receive), MIDI out (send), and USBMIDI to MIDI conversion for non-Arduino like microcontrollers. Here are some other pages of interest: Ready-Made MIDI Modules - a range of modules for "ready to go" MIDI IN and OUT for both 5V and 3V … Continue reading DIY MIDI Interfaces →

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 →

LOLShield MIDI Lighting Effects

This project goes back to the LOLShield and uses it to trigger some LED animations in response to MIDI events. https://www.youtube.com/watch?v=Hu4hc7NGaGI&feature=youtu.be 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 are the key Arduino tutorials for the main concepts … Continue reading LOLShield MIDI Lighting Effects →

PC USB to DIN MIDI IN

My PC USB MIDI interface is wired into my LoFi Orchestra at present and I don't have another one, but having already done the hard part of getting the software USB MIDI stack up and running I thought it would be fairly easy to add an actual MIDI DIN plug to create a (one-way - … Continue reading PC USB to DIN MIDI IN →

PC USB to Arduino Serial MIDI – Part 2

Having built a stand-alone PC USB to Arduino Serial MIDI link, I thought it might also be useful to have a shield that allows a direct PC USB link to the Arduino too. Warning! I strongly recommend using an old or second hand keyboard for your MIDI experiments. I am not responsible for any damage to … Continue reading PC USB to Arduino Serial MIDI – Part 2 →

PC USB to Arduino Serial MIDI

Whenever I've needed to get a computer to drive my MIDI setup I've wheeled out my Roland UM-ONE PC USB MIDI interface which gives my laptop a MIDI IN and OUT DIN plug. But if I want to get my PC to drive the Arduinos I need to then plug the UM-ONE into one of … Continue reading PC USB to Arduino Serial MIDI →

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 →
