ESP32C3 OLED Mini MIDI Montor

I've picked up a couple of really neat, small, ESP32C3 based boards with a built-in 0.42" OLED display and so whilst wondering what to do with them, I thought a small MIDI note monitor might be a bit of fun. https://makertube.net/w/3KWE9QUD2Qs9chcWwpX99R Warning! I strongly recommend using old or second hand equipment for your experiments.  I … Continue reading ESP32C3 OLED Mini MIDI Montor

Arduino Euclidean Gate Sequencer – Part 4

In this posts I describe a version of the Arduino Euclidean Gate Sequencer that implements the same user interface and most of the features of HAGIWO's brilliant build. Part 1 covered all the theory and main functions of the code. Part 2 included some hardware suggestions for connecting it to other devices. Part 3 added a rotary encoder … Continue reading Arduino Euclidean Gate Sequencer – Part 4

Arduino Euclidean Gate Sequencer – Part 3

This is another variant of my Arduino Euclidean Gate Sequencer this time using a rotary encoder and I2C display rather than a potentiometer for control. Part 1 covered all the theory and main functions of the code. Part 2 included some hardware suggestions for connecting it to other devices. Part 3 added a rotary encoder and I2C display … Continue reading Arduino Euclidean Gate Sequencer – Part 3

Arduino Clock Generator Shield PCB

This is an Arduino Uno shield design that can be used to provide up to six clock generator outputs for a sequencer. I've built it to use with my Arduino Euclidean Gate Sequencer. Arduino Clock Generator Shield PCB Build Guide Warning! I strongly recommend using old or second hand equipment for your experiments.  I am not responsible … Continue reading Arduino Clock Generator Shield PCB

XIAO SAMD21, Arduino and MIDI – Part 6

This post looks at a series of relative straight forward MIDI control projects using the Seeedstudio XIAO SAMD21 and the XIAO Expansion Board.  The projects should work with either USB MIDI or serial MIDI via an external MIDI module. Other parts in this series: Part 1 - Introduction to the XIAO SAMD21 and some projects … Continue reading XIAO SAMD21, Arduino and MIDI – Part 6

XIAO SAMD21, Arduino and MIDI

I've had a few Seeedstudio XIAO SAMD21 boards (previously known as the Seeeduino XIAO) for a while but haven't really done much with them.  I had a brief go with Circuitpython to build a CircuitPython USB to Serial MIDI Router but that is all so far.  Having been inspired by a recent post on the … Continue reading XIAO SAMD21, Arduino and MIDI

Arduino MIDI Slider OLED R2R Waveform Generator

This project moves on a step from my Arduino MIDI Slider R2R Waveform Generator and adds a small 0.96" OLED I2C display. https://youtu.be/MGwdu017e00 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 projects for the main concepts used … Continue reading Arduino MIDI Slider OLED R2R Waveform Generator

OLED MIDI Display – Part 2

As I mentioned in my previous post, it should be possible to connect multiple displays to the same microcontroller. This projects looks into that in a bit more detail. Spoiler - it almost works, but has software limitations!  Read on for details. Warning! I strongly recommend using an old or second hand keyboard for your MIDI … Continue reading OLED MIDI Display – Part 2
