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 Button Bank Select

Having tried this with a Raspberry Pi Pico (and had some odd issues with a RPi V4) I wanted to give it a go with an Arduino too. The basics have already been covered before, so this is relatively quick to set up. Warning! I strongly recommend using old or second hand equipment for your … Continue reading Arduino MIDI Button Bank Select →

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 →

Pi Pico MIDI Button Controller

Having played with MiniDexed a little now, I really wanted something that could select the different banks of voices for me. This is how I've used a Raspberry Pi Pico as a set of "bank select" switches, but the switches could be used to send any MIDI change control messages. https://youtu.be/if0iKuHCkE4 Warning! I strongly recommend … Continue reading Pi Pico MIDI Button Controller →

Raspberry Pi Pico Multi MIDI Router – Part 3

The obviously missing part of my Raspberry Pi Pico Multi MIDI Router is the use of USB MIDI. The Pico should support both USB host and device functionality, but I think you need to get into the C software development kit to do that properly, something I've not looked at yet. One of the easiest ways … Continue reading Raspberry Pi Pico Multi MIDI Router – Part 3 →

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 →

Arduino Serial MIDI Program and Control Messenger

I believe I have all the components of both sending and receiving MIDI Program and Control messages over the full range of serial interfaces from previous projects, but I'm not sure I've ever written it down in those terms. So this project aims to put that right! Warning! I strongly recommend using old or second … Continue reading Arduino Serial MIDI Program and Control Messenger →
