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 →

EuroRack 6HP Daisy Seed MCU PCB Design

Having recently acquired a Daisy Seed to play with, it seemed natural to produce an MCU board for use with my EuroRack 6HP MCU Experimenter Module. EuroRack 6HP Daisy Seed MCU PCB Build Guide. Warning! I strongly recommend using old or second hand equipment for your experiments. I am not responsible for any damage to expensive instruments! If … Continue reading EuroRack 6HP Daisy Seed MCU PCB Design →

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 →

MiniDexed EuroRack PCB Design

I've seen a number of EuroRack format MiniDexed versions now, from 3D printed panels and designs, right through to commercial modules. It's something I've been meaning to do for a while, so this is my first attempt at a take on a 8HP EuroRack format MiniDexed using a Raspberry Pi Zero 2 W. This is … Continue reading MiniDexed EuroRack PCB Design →

Waveshare Zero, Pimoroni Tiny, and Neopixels

I want to revisit my Forbidden Planet “Krell” Display looking at an alternative way to do the electronics. In particular, I'm looking at how I might embed a microcontroller in each display. This post is a short diversion into the world of some Waveshare "Zero" format devices and a bit of background on driving programmable … Continue reading Waveshare Zero, Pimoroni Tiny, and Neopixels →

Forbidden Planet “Krell” Display – MIDI CC Controller

This takes my Forbidden Planet “Krell” Display and adds some potentiometers to turn it into a MIDI CC message controller.

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 →

Raspberry Pi 2,3,4 A+/B+ Synth Cases

As a prelude to building a case for some of my MiniDexed synth PCBs I was looking for a good starting point for a Raspberry Pi 3D printed case. I've found two, but neither was quite what I wanted, so I took inspiration from the two I found and created my own. This will go … Continue reading Raspberry Pi 2,3,4 A+/B+ Synth Cases →
