CircuitPython USB to Serial MIDI Router

I've indirectly used USB and Serial MIDI with CircuitPython a few times now, but haven't explicitly shown how to use it as a simple USB (device) to serial MIDI converter. This project shows how to do that. Any CircuitPython device should be usable like this, but I've used this as an excuse to do something … Continue reading CircuitPython USB to Serial MIDI Router →

Yet Another Toy Keyboard USB MIDI Controller – Part 2

So this follows on from the first part and adds MIDI, some buttons to control the keyboard and gives it a voice of its own. https://youtu.be/NUaCPR0LRTM Warning! I strongly recommend using old or second hand equipment for your experiments. I am not responsible for any damage to expensive instruments! If you are new to microcontrollers, … Continue reading Yet Another Toy Keyboard USB MIDI Controller – Part 2 →

Yet Another Toy Keyboard USB MIDI Controller

Ok, I admit, there is a bit of a theme to some of my projects, but this keyboard that I found in a charity shop was such a dinky thing that I had to do Just One More (TM). Warning! I strongly recommend using old or second hand equipment for your experiments. I am not … Continue reading Yet Another Toy Keyboard USB MIDI Controller →

Arduino USB MIDI Mux Pot Controller

The other application I wanted for my Arduino USB MIDI Mux Step Sequencer is as a general purpose MIDI controller. In this case with 16 potentiometers mapped to MIDI CC messages. This is building on the following previous projects: Arduino USB MIDI Mux Step Sequencer Arduino and USB MIDI “Bare Metal” Raspberry Pi Synth – Part … Continue reading Arduino USB MIDI Mux Pot Controller →

Arduino USB MIDI Mux Step Sequencer

This post revisits an older project - the Arduino MIDI Mux Step Sequencer. Or more specifically, part 2 of that project that used an off-the-shelf 16-potentiometer shield for an Arduino Uno. Except this time, I've paired it with the "upgrade" to my Arduino Uno to make it USB MIDI compliant. https://youtu.be/amagp7ANns4 Warning! I strongly recommend using … Continue reading Arduino USB MIDI Mux Step Sequencer →

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 →

Raspberry Pi Pico MIDI Pedal Keyboard

Quite a number of years ago, I found an old set of organ pedals and MIDI'd them up by the crude method of wiring the pedal switches onto the connectors for the keys of an old Amstrad MIDI keyboard... It was the technology and expertise I had at the time! I stumbled across them a … Continue reading Raspberry Pi Pico MIDI Pedal Keyboard →

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 →

PC USB-MIDI to MIDI Revisited

This is another take on the PC USB to Arduino Serial MIDI once again taking the Pro Micro I used in part 2. Recall that the Pro Micro board (not to be confused with the Arduino Micro or the Pro Mini) is an Arduino Leonardo compatible smaller board, using the ATmega32U4, which means it has a … Continue reading PC USB-MIDI to MIDI Revisited →

Toy Keyboard USB Matrix Decode with the Pi Pico – Part 2

Having added USB MIDI to my "Toy Keyboard" - I wanted the option to choose either USB or serial MIDI as the output. This returns to the Toy Keyboard USB Matrix Decode with the Pi Pico project to add a serial port option. Warning! I strongly recommend using old or second hand equipment for your experiments. … Continue reading Toy Keyboard USB Matrix Decode with the Pi Pico – Part 2 →
