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 Dual MIDI Carrier

I mentioned in Raspberry Pi Pico Multi MIDI Router - Revisited that I have several dual-MIDI interfaces for a Raspberry Pi Pico designed by @VE7FIM from Twitter. In that post I built a simple proto-board carrier for the Pico. In this post I have a pcb design for something to do the same. This is definitely … Continue reading Raspberry Pi Pico Dual MIDI Carrier →

Zynthian Revisited – Part 3

Following on from my prototype IO boards for my Zynthian, here is a PCB design that will hopefully work much better. Update: Find the Build Guide here: Zynthian Revisited – Part 4 Warning! I strongly recommend using old or second hand equipment for your experiments. I am not responsible for any damage to expensive instruments! … Continue reading Zynthian Revisited – Part 3 →

Raspberry Pi v1 Model B Synth Board – Part 2

This is a bespoke PCB design for my Raspberry Pi v1 Model B Synth Board which I was using with my "Bare Metal" Raspberry Pi Synth. Update: Build Guide here: Raspberry Pi v1 Model B Synth Board – Part 3 Warning! I strongly recommend using old or second hand equipment for your experiments. I am not responsible … Continue reading Raspberry Pi v1 Model B Synth Board – Part 2 →

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) →

Bill of Materials The Raspberry Pi Pico Multi MIDI Router PCB (GitHub link below) Raspberry Pi Pico 6x H11L1 optoisolator 6x 470Ω resistors 6x 220Ω resistors 6x 33Ω resistors … Continue reading Raspberry Pi Pico Multi MIDI Router – Part 5 →

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 →

Arduino MIDI Rotary Encoder Controller – Part 2

Having just received back my Arduino MIDI Proto Shield PCBs I was thinking of a project to use them on and decided that a rotary encoder patch changer would be ideal, so this is a rebuild of my Arduino MIDI Rotary Encoder Controller using my MIDI proto shield. https://youtu.be/88TgJZBtC_8 Warning! I strongly recommend using an old or second … Continue reading Arduino MIDI Rotary Encoder Controller – Part 2 →
