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 →

Arduino MIDI Logic Analyser

After having a few issues debugging the MIDI connection for my Multi-Mode MIDI Step Sequencer I started wondering about the possibility of building a simple Arduino-based tool to help debug MIDI serial links. I'm thinking something like a MIDI "logic analyser". This is the result. Warning! I strongly recommend using old or second hand equipment … Continue reading Arduino MIDI Logic Analyser →

TFT MIDI Display – Part 3

This display is inspired by the sound and light show at the end of Close Encounters of the Third Kind. It uses the TFT MIDI Display once again. https://youtu.be/hEpZ7Zy03Vo 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 … Continue reading TFT MIDI Display – Part 3 →

OLED MIDI Display – Part 2

As I mentioned in my previous post, it should be possible to connect multiple displays to the same microcontroller. This projects looks into that in a bit more detail. Spoiler - it almost works, but has software limitations! Read on for details. Warning! I strongly recommend using an old or second hand keyboard for your MIDI … Continue reading OLED MIDI Display – Part 2 →

OLED MIDI Display

Following on from my experiments with colour TFT displays, this project takes a cheap monochrome OLED display and puts it to use with MIDI. In Part 2 I almost manage to get two displays working! https://youtu.be/Ayp-f-wmYkE Warning! I strongly recommend using an old or second hand keyboard for your MIDI experiments. I am not responsible for … Continue reading OLED MIDI Display →

TFT MIDI Display – Part 2

Building on my previous project adding a colour display to an Arduino, I thought I'd use the graphics a little by adding one of those "show the note on the stave" displays you quite often get on modern keyboards. In Part 3 I preset an alternative visualisation. https://youtu.be/p_eLd95G4zc Warning! I strongly recommend using an old or … Continue reading TFT MIDI Display – Part 2 →

TFT MIDI Display

This project uses a cheap 1.8" colour 128x160 TFT display based on a ST7735 driver chip which is available very cheaply in the usual places. The display links up to an Arduino using the SPI bus as described here and there is a nice little library to talk to it provided by Adafruit for use … Continue reading TFT MIDI Display →
