Waveshare RP2040 Matrix MIDI Monitor

Following on from my ESP32C3 OLED Mini MIDI Montor and Waveshare Zero, Pimoroni Tiny, and Neopixels this project uses a Waveshare RP2040 mini Matrix display. This is largely the same pinout as the other Waveshare boards, but includes a 5x5 programmable LED (i.e. neopixel-like) matrix. https://makertube.net/w/cdxAJJvsqsPKrzVg6xWodD Warning! I strongly recommend using old or second hand equipment for … Continue reading Waveshare RP2040 Matrix MIDI Monitor →

ESP32C3 OLED Mini MIDI Montor

I've picked up a couple of really neat, small, ESP32C3 based boards with a built-in 0.42" OLED display and so whilst wondering what to do with them, I thought a small MIDI note monitor might be a bit of fun. https://makertube.net/w/3KWE9QUD2Qs9chcWwpX99R Warning! I strongly recommend using old or second hand equipment for your experiments. I … Continue reading ESP32C3 OLED Mini MIDI Montor →

Forbidden Planet “Krell” Display – MIDI Notes – Part 2

As I mentioned in Forbidden Planet “Krell” Display – MIDI Notes I'm building a simple (in function, not in execution it would seem) MIDI note display out of my Forbidden Planet “Krell” Display. The first attempt showed there is potential, but I was rapidly reaching the limits of what an Arduino could do for me using … Continue reading Forbidden Planet “Krell” Display – MIDI Notes – Part 2 →

Forbidden Planet “Krell” Display – MIDI Notes

This is my first attempt at some kind of MIDI related visualisation for my Forbidden Planet “Krell” Display. I thought I'd start easy and simply map MIDI notes onto the segments and create a simple display. That turned out to be an awful lot more involved than I imagined... In fact, this is quite sub-optimal … Continue reading Forbidden Planet “Krell” Display – MIDI Notes →

ESP32 Simple MIDI Monitor

This project started as a bit of a test for my ESP32 WROOM Mozzi Experimenter PCB but ended up a little more functional, so I thought it worth writing up in its own right. Warning! I strongly recommend using old or second hand equipment for your experiments. I am not responsible for any damage to … Continue reading ESP32 Simple MIDI Monitor →

Simple MIDI Serial Monitor – Part 3

This is a follow-up to the following posts: Simple MIDI Serial Monitor - which shows how to use SoftwareSerial as a MIDI port to allow monitoring over the default serial port. Simple MIDI Serial Monitor – Part 2 - which shows how to use SoftwareSerial as the monitoring serial port instead. This post takes one of my … Continue reading Simple MIDI Serial Monitor – Part 3 →

XIAO SAMD21, Arduino and MIDI

I've had a few Seeedstudio XIAO SAMD21 boards (previously known as the Seeeduino XIAO) for a while but haven't really done much with them. I had a brief go with Circuitpython to build a CircuitPython USB to Serial MIDI Router but that is all so far. Having been inspired by a recent post on the … Continue reading XIAO SAMD21, Arduino and MIDI →

Simple MIDI Serial Monitor – Part 2

In this second part of my Simple MIDI Serial Monitor I show how to use MIDI callbacks to handle the data and show how an independent serial interface could be used as the diagnostic port, thus allowing the hardware serial port to be used with MIDI. Warning! I strongly recommend using old or second hand equipment … Continue reading Simple MIDI Serial Monitor – Part 2 →

Simple MIDI Serial Monitor

This blog is full of MIDI projects, but I've just realised that I've never really done a "MIDI Data Dumper" type project, so building on my Simple MIDI Monitor and using the many MIDI transport options from Arduino Multi MIDI Merge, here is a serial MIDI data dumper. In Part 2 I show how to do the … Continue reading Simple MIDI Serial Monitor →

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 →
