Raspberry Pi Pico MIDI Channel Muter

This project uses a Pimoroni RGB Keypad with a Raspberry Pi Pico to create 16 "mute" switches for MIDI, one for each MIDI channel. https://youtu.be/8KiXT91sSk8 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 tutorials for the … Continue reading Raspberry Pi Pico MIDI Channel Muter →

Trinket M0 USB MIDI Interface for the Shruthi Synth

I managed to pick up a Shruthi synth second hand a while back and so far, I really like it, but I've not really had a chance to properly explore it yet. One thing I'd like to do is build some kind of control interface for it so I'm not having to navigate all the … Continue reading Trinket M0 USB MIDI Interface for the Shruthi Synth →

Getting Started with the Raspberry Pi Pico C/C++ SDK and TinyUSB MIDI

I've been meaning to take a proper look at the Raspberry Pi Pico C/C++ SDK for quite some time, but have been putting it off. With good reason it would appear! But I've finally got to the start of being able to build the Tiny USB test MIDI application myself and so have a good … Continue reading Getting Started with the Raspberry Pi Pico C/C++ SDK and TinyUSB MIDI →

Arduino VS1053 General MIDI Synth – Part 3

Having prototyped a patch changer for my Arduino VS1053 General MIDI Synth this shows how that can be achieved in a slightly more useful manner using a shift register to control the 7-segment display. It also follows through a build using my Arduino MIDI Proto Shield PCB. Warning! I strongly recommend using an old or second hand keyboard … Continue reading Arduino VS1053 General MIDI Synth – Part 3 →

Raspberry Pi Pico MIDI Splitter (TTL)

This is a version of my Raspberry Pi Pico MIDI Splitter that omits the MIDI sockets and instead provides a 5V UART TX style output for use directly with 5V microcontrollers. Update: Find the Build Guide here: Raspberry Pi Pico MIDI Splitter (TTL) - Part 2 Tutorials used in this project: Raspberry Pi Pico MIDI Channel Router … Continue reading Raspberry Pi Pico MIDI Splitter (TTL) →

Arduino VS1053 General MIDI Synth – Part 2

Another I've wanted to do with my Arduino MIDI Proto Shield PCB is link it with my Arduino VS1053 General MIDI Synth to provide a means of selecting the voice from the shield itself. As I almost always pair my VS1053 shield with an off the shelf MIDI module to use it, this seems like a natural thing … Continue reading Arduino VS1053 General MIDI Synth – Part 2 →
