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 →

Pi Day MIDI Sequencer

If you write your dates month first, then 14th March is recognised as Pi day i.e. 3.14.(2022) in this case. I've long had the idea of doing something MIDI or sequencer related to number sequences. I'd like to do something with the Online Encyclopedia of Integer Sequences (OEIS) at some point, but as it is … Continue reading Pi Day MIDI Sequencer →

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 →

Pico Dual-core MIDI Visualisations

I started this project as I had just bought two new toys from The Pi-Hut: Waveshare RGB Full-colour 16x10 LED Matrix Panel Waveshare 4-Digit 8-Segment Display Module My initial thinking was to re-run the Pico Unicorn MIDI Visualiser and the Arduino MIDI 7 Segment Controller with these new devices and a Pico. But whilst playing around, I … Continue reading Pico Dual-core MIDI Visualisations →

MIDI IN for the Raspberry Pi Pico

I was in need of another MIDI IN device, so I thought it would be useful to have another "pack" style interface that supported MIDI IN for new MIDI monitoring type projects. You can see all the other DIY options for Pico MIDI interfaces here: DIY MIDI Interfaces. Warning! I strongly recommend using old or second … Continue reading MIDI IN for the Raspberry Pi Pico →

Raspberry Pi Pico MIDI Channel Merger

This is my second try at using the Raspberry Pi Pico Programmable Input Output (PIO) peripherals. My previous attempt was for a MIDI channel router. This time, I'm building a MIDI channel merger. The basic idea is to use the Raspberry Pi PIO to create 8 MIDI IN ports and merge them all into a … Continue reading Raspberry Pi Pico MIDI Channel Merger →

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 MIDI LED Step Sequencer with MCP3008

Having now experimented with an SPI eight-way analog to digital converter in the shape of the MCP3008, I wanted to build a step sequencer where the type of analog input was configurable. This project allows you to choose between the following options for controller the steps of the sequencer: The native analog inputs on the … Continue reading Arduino MIDI LED Step Sequencer with MCP3008 →
