USBMIDI to MIDI Shield

I've been using my Korg Minikeys for testing a number of these projects, which usually means breaking out my Mini USB-MIDI to MIDI converter, but that means I need to find jumper wires, power, etc, so I thought it would be interesting to mount the appropriate components onto an Arduino pro-shield to create an entire "USB … Continue reading USBMIDI to MIDI Shield →

TFT MIDI Display – Part 2

Building on my previous project adding a colour display to an Arduino, I thought I'd use the graphics a little by adding one of those "show the note on the stave" displays you quite often get on modern keyboards. In Part 3 I preset an alternative visualisation. https://youtu.be/p_eLd95G4zc Warning! I strongly recommend using an old or … Continue reading TFT MIDI Display – Part 2 →

TFT MIDI Display

This project uses a cheap 1.8" colour 128x160 TFT display based on a ST7735 driver chip which is available very cheaply in the usual places. The display links up to an Arduino using the SPI bus as described here and there is a nice little library to talk to it provided by Adafruit for use … Continue reading TFT MIDI Display →

Simple Synth IO Shield

I have a range of synthesizer chips and modules and some of those come on shields but I needed a way to hook up some potentiometers in a simple manner for testing and playing around. To date I've build separate modules (some examples here and here). One thing I often find is that music shields … Continue reading Simple Synth IO Shield →

WS002 – MIDI In, MIDI Monitors and Effects

This second worksheet looks at projects related to receiving and processing MIDI messages, providing a single list of parts and a suggested "building order". This worksheet links together the following projects: Simple MIDI Monitor Simple MIDI Monitor - part 2 Arduino MIDI Note Monitor Arduino MIDI Channel Monitor Arduino MIDI Tone Module Arduino Multi MIDI … Continue reading WS002 – MIDI In, MIDI Monitors and Effects →

Mozzi Output Circuit – Part 2

The simple Mozzi Output Circuit is fine for experimenting but when it comes to combining signals it can really do some damage - I may have trashed the small amp I was using for my experiments - remember my warning - I strongly recommend using an old or second hand keyboard for your MIDI experiments. I … Continue reading Mozzi Output Circuit – Part 2 →

Arduino MIDI VS1053 Synth – Part 2

I'm planning a use of the VS1053 shield but need to be able to pre-select which instruments to play and which channels to respond to. This revisits the Arduino MIDI VS1053 Synth and adds that functionality. Warning! I strongly recommend using an old or second hand keyboard for your MIDI experiments. I am not responsible for any … Continue reading Arduino MIDI VS1053 Synth – Part 2 →

Arduino MIDI Filter

I am working on something that might allow several of my projects to come together, but one issue I'm having is the overheads of processing unnecessary MIDI traffic are causing delays in playing for some of the modules. So I thought I'd create a MIDI filter that can be used to see all the traffic … Continue reading Arduino MIDI Filter →

Arduino MIDI R2R Digital Audio

With all the excitement of experimenting with Mozzi, I never really finished my R2R digital audio series. This final part adds MIDI to the R2R shield I built in Arduino R2R Digital Audio – Part 3. https://youtu.be/i6Y9QiTxTeQ Warning! I strongly recommend using an old or second hand keyboard for your MIDI experiments. I am not responsible for … Continue reading Arduino MIDI R2R Digital Audio →

Mozzi Output Circuit

As part of the Arduino Multi-pot Mozzi FM Synthesis project I put together a simple Mozzi output filter circuit, but it stopped working. After having a bit of a look and poke about it it turns out that the jack socket was faulty, so I ordered a different type of socket and started again. This is … Continue reading Mozzi Output Circuit →
