Arduino MIDI Telephone Ringer – Part 2

Following on from part 1, I've added BT style sockets and upgraded the ringer to ring two phones. Polytelephony if you will. In part 3, I switch to an Arduino Nano and put all the circuitry into a box. https://youtu.be/IBBd9z4hKYw Warning! I strongly recommend using old or second hand equipment for your experiments. I am … Continue reading Arduino MIDI Telephone Ringer – Part 2 →

Arduino Serial MIDI Program and Control Messenger

I believe I have all the components of both sending and receiving MIDI Program and Control messages over the full range of serial interfaces from previous projects, but I'm not sure I've ever written it down in those terms. So this project aims to put that right! Warning! I strongly recommend using old or second … Continue reading Arduino Serial MIDI Program and Control Messenger →

Arduino MIDI Telephone Ringer

One thing I love about those vintage rotary telephones is the characteristic ring. But making them do that outside of being plugged into the PSTN isn't easy. But I wanted to see if I could make it work over MIDI, so this is my approach. In part 2 I add some BT style sockets and … Continue reading Arduino MIDI Telephone Ringer →

Yet Another Toy Keyboard USB MIDI Controller – Part 2

So this follows on from the first part and adds MIDI, some buttons to control the keyboard and gives it a voice of its own. https://youtu.be/NUaCPR0LRTM Warning! I strongly recommend using old or second hand equipment for your experiments. I am not responsible for any damage to expensive instruments! If you are new to microcontrollers, … Continue reading Yet Another Toy Keyboard USB MIDI Controller – Part 2 →

Simple MIDI Serial Monitor – Part 2

In this second part of my Simple MIDI Serial Monitor I show how to use MIDI callbacks to handle the data and show how an independent serial interface could be used as the diagnostic port, thus allowing the hardware serial port to be used with MIDI. Warning! I strongly recommend using old or second hand equipment … Continue reading Simple MIDI Serial Monitor – Part 2 →

Simple MIDI Serial Monitor

This blog is full of MIDI projects, but I've just realised that I've never really done a "MIDI Data Dumper" type project, so building on my Simple MIDI Monitor and using the many MIDI transport options from Arduino Multi MIDI Merge, here is a serial MIDI data dumper. In Part 2 I show how to do the … Continue reading Simple MIDI Serial Monitor →

Yet Another Toy Keyboard USB MIDI Controller

Ok, I admit, there is a bit of a theme to some of my projects, but this keyboard that I found in a charity shop was such a dinky thing that I had to do Just One More (TM). Warning! I strongly recommend using old or second hand equipment for your experiments. I am not … Continue reading Yet Another Toy Keyboard USB MIDI Controller →

Vintage Rotary Phone MIDI Controller – Part 7

Having built my adaptor into a small box, I've gone back to add a mode button so I can include all the different applications into a single sketch. This builds on the previous parts in this series. Part 1 - Understanding the telephone hardware and interfacing to an Arduino. Part 2 - Decoding the rotary … Continue reading Vintage Rotary Phone MIDI Controller – Part 7 →

Arduino Timed Relay

I've an idea for a project that needs to wait for a certain length of time and then trigger a relay. So whilst this isn't a specifically musical post at present, this is the detail of how I got that part of the project ready to go. Warning! I strongly recommend using old or second … Continue reading Arduino Timed Relay →

Arduino Slider Phased Rhythms

There is an interesting video going around social media of someone playing a simple drum beat at 120bpm, 119bpm and 121bpm and you can hear the rhythms going in and out of phase, so I thought it perhaps time to update my Arduino Mux Slider Phased Relays to actually play a rhythm. https://youtu.be/hpoJ7eNfn_8 Warning! I … Continue reading Arduino Slider Phased Rhythms →
