Arduino Multi MIDI Merge – Part 2

I've built a number of MIDI merge projects so far (for Arduino and Pico), but they've always taken a relatively simple approach to the merge. They had all ensured that MIDI messages won't be corrupted as they are merged - i.e. only complete messages will be passed on - but they've done nothing to interpret the … Continue reading Arduino Multi MIDI Merge – Part 2 →

Raspberry Pi Pico SysEx “Librarian”

I've seen a few dedicated units for sending and managing patches for older synths and whilst they look really neat, I thought it would be worth me having a go and seeing what I could do myself. This is my first attempt at pretty much the simplest hardware "patch librarian" I could imagine - it … Continue reading Raspberry Pi Pico SysEx “Librarian” →

Pi Pico MIDI Button Voice Select

This is an alternative take on my Arduino MIDI Button Voice Select this time combining it with both my Pi Pico MIDI Button Controller with a hint of the CircuitPython USB to Serial MIDI Router too. The end result is a voice and bank selector that will also act as a USB MIDI to serial MIDI converter. In … Continue reading Pi Pico MIDI Button Voice Select →

Arduino MIDI Button Voice Select

Having got as far as an Arduino MIDI Button Bank Selector I went off an ordered some cheap 8-way button pcbs so I can start to experiment with a voice selector too. As I think I mentioned before, I'd really like a set of buttons like you'd find on a real synth 🙂 This is the … Continue reading Arduino MIDI Button Voice Select →

Arduino MIDI Multi MUX Step Sequencer

This applies the same extension from the Arduino MIDI Multi MUX Controller to the Arduino MIDI Mux Step Sequencer showing how it could be expanded to support 32 potentiometers or more in a MIDI step sequencer. Warning! I strongly recommend using old or second hand equipment for your experiments. I am not responsible for any damage … Continue reading Arduino MIDI Multi MUX Step Sequencer →

Arduino MIDI Multi MUX Controller

This project revisits my Arduino MIDI Mux Step Sequencer showing how it could be expanded to support 32 potentiometers or more in a MIDI controller. Warning! I strongly recommend using old or second hand equipment for your experiments. I am not responsible for any damage to expensive instruments! These are the key Arduino tutorials for the … Continue reading Arduino MIDI Multi MUX Controller →

“Bare Metal” Raspberry Pi MiniDexed DX7

One project I've had my eye on for some time is Dexed: "Dexed is a multi platform, multi format plugin synth that is closely modeled on the Yamaha DX7". More specifically I noticed there was a version for the Teensy called microDexed that I really wanted to try; that it is also one of the synth … Continue reading “Bare Metal” Raspberry Pi MiniDexed DX7 →

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 Slider Phased Rhythms

There is an interesting video going around social media of someone playing a simple drum beat at 120bpm, 119bpm and 121bpm and you can hear the rhythms going in and out of phase, so I thought it perhaps time to update my Arduino Mux Slider Phased Relays to actually play a rhythm. https://youtu.be/hpoJ7eNfn_8 Warning! I … Continue reading Arduino Slider Phased Rhythms →
