Raspberry Pi Pico MIDI Channel Merger

This is my second try at using the Raspberry Pi Pico Programmable Input Output (PIO) peripherals. My previous attempt was for a MIDI channel router. This time, I'm building a MIDI channel merger. The basic idea is to use the Raspberry Pi PIO to create 8 MIDI IN ports and merge them all into a … Continue reading Raspberry Pi Pico MIDI Channel Merger →

Raspberry Pi Pico MIDI Channel Router

Ever since I got hold of a Raspberry Pi Pico microcontroller I wanted to try out the Programmable Input Output (PIO) peripherals. I've also been on the lookout for microcontrollers with more serial ports than the usual one or two. The best I've found so far are ATmega2560 boards with four and the Teensy range … Continue reading Raspberry Pi Pico MIDI Channel Router →

Single Pin MIDI Channel Selector – Part 2

As I mentioned in the Single Pin MIDI Channel Selector it would be nice to use a "DIP switch" on a small circuit board to give me my MIDI channel selection switch. Here is a small board that can plug directly into an Arduino's headers. Warning! I strongly recommend using old or second hand equipment for … Continue reading Single Pin MIDI Channel Selector – Part 2 →

Single Pin MIDI Channel Selector

One thing that has been missing from all of my MIDI projects so far is some means of configuring the MIDI channel without having to reload code. There are a number of approaches, but I wanted one that used the minimal amount of IO. This documents one option. In part 2 I build this into … Continue reading Single Pin MIDI Channel Selector →
