Duppa I2C MIDI Controller – Part 1

I've had my eye on Duppa's rather neat looking I2C LED rings and rotary encoders for some time and finally pushed "go" on getting a couple. I want to use them as the basis for a MIDI controller but this post is just my "getting to know them" post. Part 1 - getting to know the … Continue reading Duppa I2C MIDI Controller – Part 1 →

Almost “All in one” MiniDexed IO Options

As I was browsing around I happened to notice a couple of interesting add-on boards that comprise a OLED display, rotary encoder and some buttons. With the addition of a I2S DAC (or just using the existing PWM output) these make a really interesting option for MiniDexed IO. Warning! I strongly recommend using old or … Continue reading Almost “All in one” MiniDexed IO Options →

Simple MIDI Touch Button Keyboard

I've grabbed some very cheap TTP223-based touch pad PCBs so this is showing how they can be used as a replacement button in a simple Arduino MIDI controller. 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 … Continue reading Simple MIDI Touch Button Keyboard →

Simple MIDI Transpose

I've done a number of MIDI processing projects, but was always planning to go back and build up some kind of catalogue of common actions that could be taken. But so far I've not done it, but when a question came in asking about the possibility of a MIDI transpose function, I thought I'd put … Continue reading Simple MIDI Transpose →

EuroRack 6HP Daisy Seed MCU PCB Build Guide

Here are the build notes for my EuroRack 6HP Daisy Seed MCU PCB. Please Note: At the time of writing this has shown to be able to power up and nothing more. None of the IO or audio functions have been tested yet! I'll update this post once I have some test applications to show … Continue reading EuroRack 6HP Daisy Seed MCU PCB Build Guide →

Waveshare RP2040 Matrix MIDI Monitor

Following on from my ESP32C3 OLED Mini MIDI Montor and Waveshare Zero, Pimoroni Tiny, and Neopixels this project uses a Waveshare RP2040 mini Matrix display. This is largely the same pinout as the other Waveshare boards, but includes a 5x5 programmable LED (i.e. neopixel-like) matrix. https://makertube.net/w/cdxAJJvsqsPKrzVg6xWodD Warning! I strongly recommend using old or second hand equipment for … Continue reading Waveshare RP2040 Matrix MIDI Monitor →
