Lo-Fi Orchestra – Serenade

The Lo-Fi Orchestra presents Derek Bourgeois wonderfully quirky Serenade.  Who doesn't love a piece of music with a stylistic direction of "piacevole" in time signatures of 11/8, 13/8, an occasional 7/8 and finishing with a bar of 3/8. This piece features the Arduino PWM MIDI Synthesis with Mozzi and the Arduino MIDI R2R Digital Audio with a … Continue reading Lo-Fi Orchestra – Serenade →

Analog Keypad Tone Controller

I've picked up a couple of cheap 3x4 keypads so thought I'd look at its potential as a music controller. https://youtu.be/C1n5NBVvfLg 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 main concepts used … Continue reading Analog Keypad Tone Controller →

200th Post!

This is the 200th post on this blog! As I've recently celebrated 1 year of posts, rather than a new project for this occasion, I thought it might be interesting to look back over some of the past 199 posts and pull out a few of my favourites. A good number of posts have been … Continue reading 200th Post! →

Toy Keyboard USB Matrix Decode with the Pi Pico

I never really got back to looking at my "Toy Keyboard" - I wanted to do the same as the Vintage Phone - create a USB MIDI version with Circuitpython.  Well now I have.  Here is the result. https://youtu.be/VNmp3-mwysI Warning! I strongly recommend using old or second hand equipment for your experiments.  I am not … Continue reading Toy Keyboard USB Matrix Decode with the Pi Pico →

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 →

Arduino USB MIDI Merge

This project uses two off-the-shelf Arduino shields to provide a USB and Serial MIDI merge to a single Serial MIDI OUT. https://youtu.be/AB49UNDIrcM 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 main concepts … Continue reading Arduino USB MIDI Merge →

Arduino MIDI Logic Analyser

After having a few issues debugging the MIDI connection for my Multi-Mode MIDI Step Sequencer I started wondering about the possibility of building a simple Arduino-based tool to help debug MIDI serial links. I'm thinking something like a MIDI "logic analyser".  This is the result. Warning! I strongly recommend using old or second hand equipment … Continue reading Arduino MIDI Logic Analyser →

Multi-Mode MIDI Step Sequencer – CDR Format – Part 2

Part 3 details the design of a panel using a PCB manufacturer. https://youtu.be/YmQ7j-tDudk Warning!

These are the key Arduino tutorials for the main concepts used in this project: Arduino Analog Input Arduino Digital … Continue reading Multi-Mode MIDI Step Sequencer – CDR Format – Part 2 →

Multi-Mode MIDI Step Sequencer – CDR Format

When I put together the Multi-Mode MIDI Step Sequencer it was with an eye to creating some kind of "modular" style panel format.  This post documents the building of a "CDR format" (CD Rack Format) panel version. Part 1 (this post) details the build and testing of the panel. Part 2 updated and enhanced the Multi-Mode … Continue reading Multi-Mode MIDI Step Sequencer – CDR Format →
